This document provides guidelines for studying ESC or ACC guidelines for cardiology exams. It recommends starting with tables and algorithms, then reading the full text as needed. Numbers in tables and important trials listed in guidelines are important for MCQ exams. Class I and III recommendations are most important to know, followed by Class II. When time is limited, focus on the most recent guidelines.

How to study guidelines?
1. ESC or ACC?
-ESC is more popular especially in Egypt
So it is the main bulk of studying
-You will need to study the ACC if is the most recent
-If you have enough time, study ESC very well, then have a rapid
look on ACC(recommendations only not full text(
2. Pocket or full text?
-MD level, full text is a must to know the trials
-Master level, study tables and algorithms very well then if
something is unclear, see text
3. -Always start first with tables and algorithms, finish them all first,
study them very well, then go to full text as a last step. When you
do this, you will find the text is easier and will answer the
questions that have been raised by your mind after you have
studied the tables
4. Numbers in tables is very important in MCQ exams especially
those which are not popular in practice
5. When to study Full text, you have to Write the most important
notes in a separate paper by yourself
Final revision before exams, you can revise the tables, algorithms
and your notes about the full text
6. ESC site provide a beautiful summary in form of slide set (power
point presentation), it can help you if you are in hurry

4. 3
7. In the ESC guidelines, you will find what's new in these guidelines,
read it rapidly. It is mainly done for those who have read the old
guidelines and they want rapid update. But at exam level, you need
to know mainly the new recommendations
8. You should know the difference between
Class I (it is recommended(
Class III (it is not recommended
Class II-a (should be considered(
Class II-b (may be considered(
As in MCQ, he can give you statement and gives you the above
options
9. You should know very well what is class I and what is class III
recommendations, these are most important, Followed by class II
indications
10.In the beginning of each ESC guidelines, you will find a list with
all trials included in these guidelines
This list is very important, as it will help you you to know the
important trials
11.Do not be surprised when you find a different level of
recommendations for the same statement but in different guidelines
Simply because the writing committee is different
My advice is the study the recommendations in the original topic
12.-Start with the most recent guidelines as these guidelines will not
change before exams

Peripartum cardiomyopathy (PPCM(
1. Defined as unexplained cardiomyopathy, EF less than 45% that
occur in the last month of pregnancy or the first 5 months post-
partum
2. Pathophysiology is thought to be related to prolactin degradation
product which has a myocardial toxicity which explain the benefit
of anti-prolactin which is Bromocriptine
3. Other theories include autoimmune, myocarditis, oxidative stress
4. Predictors of poor prognosis include dilated LVEDD more than 60
mm, EF less than 30% and RV involvement
5. According to the ESC guidelines for heart disease with pregnancy,
Bromocriptine is a class II b indication for PPCM

I-Bromocriptine 2.5 mg once daily for 1 week
II-Bromocriptine 2.5 mg twice daily for 2 weeks then 2.5 mg once
daily for 6 weeks
-The first regimen for uncomplicated cases
-The second regimen is used if the patient is presenting with
cardiogenic shock or EF less than 25%
7. You must give parenteral anticoagulation for patients on
Bromocriptine(either prophylactic or therapeutic(
8. You must continue on ant-failure measures for at least 6 months
after recovery of normal LV function
9. Women who did not recover LV EF above 50% should be
prohibited from further pregnancies
10.Women who have recovered normal LV function still have a
higher risk than those who did have PPCM and risk of recurrence
as well

for two consecutive readings
12.As a general rule, NOACs are stopped 2 days before surgery
(except for dabigatran in patients with CKD, will need longer
interval(
13.As a general rule, you can restore NOACs 3 days after surgery
14.As a general rule, the risk of GIT Bleeding with NOACs is more
than Warfarin except Apixaban 5mg twice or dabigatran 110 mg
twice which have a comparable GIT Bleeding risk similar to

Tips and tricks in management of
Dyslipidemia
1. Atherogenic lipids include LDL and VLDL
2. Apo B is the lipoprotein included in the LDL and VLDL
3. Apo B and Non HDL cholesterol are more representative for
atherogenic risk more than LDL as both of them reflect LDL plus
VLDL
4. Targets in management of dyslipidemia are
LDL
Then non HDL-cholesterol
Then Apo B
5. Lipoprotein(a) is modified form of LDL, level 50 mg or more is
considered risk enhancer, it should be requested in patients with
family history of premature CAD or personal history of
unexplained CAD
6. According to ESC guidelines
-In patients with very high cardiovascular risk, Target LDL
is below 70mg, or if LDL from 70 to 135, Target is 50%
reduction
-In patients with high cardiovascular risk, Target LDL is
below 100, if LDL from 100 to 200, Target is 50%
reduction
-In patients with Moderate cardiovascular risk, Target LDL
is below 115
-Non HDL Target are 30 mg above LDL target
-Apo B Target
Less than 80 mg in very high cardiovascular
Less than 100 in high cardiovascular risk

10. 9
7. According to American guidelines, Patients with 10 year risk of
ASCVD 7.5 % and triglycerides level from 175-499 mg are
indicated for Statin
8. Primary prevention include:
Patients with DM
Patients with LDL level 190 mg or more
Patients with high CVD risk
9. High intensity Statin(50% reduction of baseline LDL) include
Atorvastatin 40-80 mg, Rosuvastatin 20-40mg
10.Moderate intensity Statin(30 to less than 50%) reduction of
baseline LDL: Atorvastatin 10-20 mg, Rosuvastatin 5-10 mg
11.Chronic kidney disease not on dialysis, 10 year risk of ASCVD
more than 7.5% are indicated for statin
12.It is class III to initiate Statin for patients on dialysis
13.It is class II-b to continue Statin for patients who Required dialysis
14.The only Statin which did not need dose modifications in CKD is
atorvastatin
15.Fasting lipid profile is recommended if the patient was maintained
on statins, for diagnosis of familial hypercholesterolemia and if
initial triglycerides more than 400 mg.

calcium handling during the cardiac cycle
3. Type of patient:
HFpEF is typically a disease of elderly women
-More in elderly
-More in female
-Typically associated with AF, hypertension, LVH,
CAD, Obesity, DM, CKD

PCSK9 inhibitors
1. PCSK9 Is proprotein convertase subtilisin kexin 9 enzyme
2. In LDL metabolism, LDL bind with LDL receptor followed by
endocytosis
3. Before lysosomal degradation, unbinding of the LDL receptor from
LDL occur
4. PCSK9 prevent unbinding of LDL from its receptor
5. So, there is a destruction of LDL receptor with a subsequent
increase in LDL level (no receptors to bind with)
6. This finding was observed in patients with Familial
hypercholesterolemia, in whom, there is a gain of function
mutation in PCSK9 which explain the main pathological findings
responsible for hypercholesterolemia in these patients (which is
decreased LDL receptors(
7. So, PCSK9 inhibitors (Alirocumab, Evolocumab) are monoclonal
antibodies results in up regulation of LDL receptors with further
increase in LDL uptake and metabolism
8. The main indications of PCSK9 inhibitors are:
Patients with established ASVCD and LDL above 70mg despite
maximally tolerated doses of Statin and Ezetimibe
Or Familial hypercholesterolemia with failure to reach target LDL
despite maximally tolerated dose of Statin and Ezetimibe
9. Trials:
Odyessy trial (Alirocumab), ACS
Fourier trial (Evolocumab), stable ASCVD
10.Trade name
-Repatha(Evolocumab)
-Praluent(Alirocumab(
Given as SC injection every 2 weeks

Angiotensin receptor-neprilysin inhibitor
(ARNI(
1. ARNI is considered a breakthrough in management of heart failure
2. ARNI is composed of 2 drugs:
Angiotensin receptor antagonist :Valsartan
Neprilysin inhibitor:Sacubitril
3. Neprilysin is an enzyme responsible for breakdown of natriuretic
peptides as well as bradykinin
4. Mechanism of action:
-Inhibition of neprilysin will result in increase in
natriuretic peptides with a subsequent increase in
diuresis and natriuresis and vasodilation
-Valsartan block angiotensin receptor with a subsequent
blockage of RAAS system>> improve myocardial
remodelling and after load reduction
5. Why sacubitril is combined with ARB not ACEI?
-A previous trial of combining neprilysin inhibitor
with ACEI (Omapatrilat) failed and ended with
angioedema as both ACEI and neprilysin inhibitor
prevent breakdown of bradykinin, so resulted in
angioedema
-For the same reason, when you switch from ACEI to
ARNI, you have to wait for 36 hours, while you can
give ARNI in the time of next dose of ARBs if the
patient is previously maintained on ARB

20. 19
6. Evidence of use:
-Paradigm HF trial compared ARNI VS. Enalapril in
Patients with HFrEF, showed 22% reduction in
Composite Endpoint of CV mortality and HF
Hospitalization
-As regard use in HFpEF, paramount trial failed to
Improve outcomes and Paragon trial is ongoing
7. Guidelines:
-ESC recommended ARNI only if patient is still
symptomatic after the standard HF therapy as a
substitute for ACEI or ARBs
-ACC guidelines allowed use of ACEI or ARBs or
ARNI as a first line
8. Contraindications of ARNI:
-History of angioedema
-Liver cirrhosis Child C
-Pregnancy
-Hyperkalemia
9. Dose modifications:
Start with half standard dose (start with 50 mg twice
Daily( in any of the followings:
-CKD, GFR less than 30ml
-Liver cirrhosis Child B
-Patients previously not maintained on ACEI or ARBs
Or maintained but on low doses (not equivalent to
enalapril 10 mg twice)

21. 20
10.Standard dose is 100 mg twice daily, Can be increased after 2-4
weeks interval to 200 mg twice daily
11.Recently, Transition trial, and Pioneer HF trial showed safety of in-
hospital initiation of ARNI for patients admitted with acute
decompensated HF after stabilization of their condition and before
hospital discharge

22. 21
Cardiac amyloidosis
1. Types:
-Primary (AL) amyloidosis due to deposition of Amyloid light
chain most commonly due to multiple myeloma
-Secondary (AA) amyloidosis due to deposition of Amyloid A
protein, in Chronic Inflammatory state Such as rheumatoid arthritis
-Familial Amyloidosis (ATTR) due to deposition of mutated Type
of transthyretin
-Senile systemic amyloidosis (SSA) due to deposition of wild type
of transthyretin
2. One of the most common causes of Restrictive cardiomyopathy
3. ECG:
Low voltage despite increased wall thickness in Echocardiography,
pathological Q waves in absence of ischemia
4. Echo:
-Ground glass appearance of the myocardium with 2 small
ventricles, 2 large atria
-Grade III diastolic dysfunction
-Thickened AV valves
- Thickened interatrial septum
- Marked LA dysfunction that can be manifested as very small A
wave in PW Doppler(called atrial arrest)
-MR, TR, PH
-Pericardial effusion
5. -Diagnosis:
-Abdominal fat aspirate, congo red stain
-Free light chain assay, protein electrophoresis, immune-fixation,
bone marrow aspirate (to diagnose primary amyloidosis(
-Genetic study to diagnose Familial type
-Cardiac-MRI for tissue characterization

23. 22
-Technitium scintigraphy can be used for diagnosis of TTR related
amyloidosis
6. Associated Features:
-Carpal tunnel syndrome
-Postural hypotension (due to peripheral neuropathy secondary to
transthyretin
-Hepatomegaly disproportional to degree of congestion
7. Treatment:
I- Tafamidis is now approved for treatment of Familial type with
autonomic neuropathy based on ATTR-ACT trial, Decrease all-
cause mortality and HF hospitalization.
-There are 2 preparations: Vnydaqel and Vyndamax
Both are contraindicated in Pregnancy
II- Anti-failure measures
-ACEI used cautiously as it can result in profound hypotension
-Beta blocker used cautiously as there is fixed stroke volume and
COP depend mainly on HR
-Better to avoid digitalis due to high incidence of digitalis toxicity
III- Anticoagulation:
For AF regardless CHADS-VASc score due to high incidence of
LAA thrombus due to marked reduction of LA function
IV-Liver transplantation can be considered in Familial type
V-Chemo therapy and steroid for primary type
VI-Immunosuppression and anti-inflammatory in secondary
type

24. 23
10 points to remember about role of
prophylactic revascularization before
elective non cardiac surgery
1- Control of myocardial ischaemia before surgery is recommended
whenever non-cardiac surgery can be safely delayed.
2-There is, however, no indication for routinely searching for the
presence of myocardial (silent) ischaemia before non-cardiac surgery.
3-The main reason for pre-operative myocardial revascularization is the
potential prevention of perioperative myocardial ischaemia that leads to
necrosis or electric/haemodynamic instability at the time of surgery.
4-Coronary pathology underlying fatal perioperative myocardial
infarctions revealed that two-thirds of the patients had significant left-
main or three-vessel disease.
5- Most of the patients did not exhibit plaque fissuring and only one-third
had an intracoronary thrombus.
6-These findings suggest that a substantial proportion of fatal
perioperative myocardial infarctions may have resulted from low-flow,
high-demand ischaemia, owing to the stress of the operation in the
presence of fixed coronary artery stenosis and therefore amenable to
revascularization.
7-In patients who underwent coronary angiography before vascular
surgery, a number of non-fatal perioperative myocardial infarctions
occurred as a consequence of plaque rupture in arteries without high-
grade stenosis.

25. 24
8-These results are not surprising, considering the extreme and complex
stress situations associated with surgery—such as trauma, inflammation,
anaesthesia, intubation, pain, hypothermia, bleeding, anaemia, fasting,
and hypercoagulability—which may induce multiple and complex
pathophysiological responses.

Cardiology pearls (part I)
1. RHD : almost always involve mitral valve with or without
other Valves
2. HF with impaired LV function: Keep serum Potassium
above 4.5meq to avoid precipitation of ventricular
arrhythmia
3. Atrial flutter carries the Same thrombo-embolic risk as AF
and should managed as AF as regards indication of
anticoagulation
4. Always ask for CXR in patient with chest pain and normal
ECG
5. Always check for lead AVR in ECG before interpretation
(you may activate primary PCI cath team based on wrong
ECG(
6. ECG leads V1-V2 in the fourth intercostal space (not the
second space(
7. In left sided infective endocarditis , ask for multislice CT
cerebral angiography to exclude mycotic aneurysm
8. In reading CXR , always look for lung apex it is frequently
missed
9. In infective endocarditis,a always ask for serology for
aspergillus, Bartonella, Brucella, Coxiella, legionella
10.Hypotension after Coronary angiography either due to:
A-Hypovolemic shock:
Bleeding from sheath or retroperitoneal hematoma
B-Cardiogenic shock:

C-Anaphylactic Shock:
From contrast
D: Vasovagal: pain during sheath removal

28. 27
Cardiology pearls (Part II)
1. Any hospitalized patient who develop new onset AF during
hospital stay, you should suspect Pulmonary embolism
2. Enoxaprin is contraindicated if GFR is less than 15 m and if
GFR is from 15-30 we give 1mg/Kg every 24 hours as a
therapeutic dose
3. Any wide complex tachycardia in patient with ischemic
heart disease should be managed as VT until proved other
wise
4. Causes of very high ESR(more than 100 In first hour)
includes:
-TB
-Connective tissue disorders
-Malignancy
5. D-Dimer is a good negative test in pulmonary embolism but
not specific
6. Uro-sepsis is the most common cause of delirium in elderly
7. Anemia in old age carries the possibility of malignancy and
ideally upper and lower GIT endoscopy should be done
8. It is recommended to do lipid profile within 48 hours of
onset of ACS as after that there is a possibility of false low
cholesterol levels due to enhanced sympathetic activity and
lipolysis
9. You can calculate the LDL level from this equation
(LDL=Total cholesterol -(HDL + Triglycerides/5(
10.You can calculate the creatinine clearance from this equation
(140-ageX weight(/72X serum creatinine ,and multiply by
0.85 if female

29. 28
Cardiology pearls (Part III(
1. Metolazone is the only thiazide that can be used in Renal
impairment
2. It better to avoid imipenem(Tienam) and
levofloxacin(Tavanic) in elderly as the former can causes
convulsions and the latter can precipitate encephalopathy
3. The most common congenital heart disease is bicuspid aortic
valve
4. Bicuspid aortic valve can be associated with
-Aortopathy and aortic aneurysm
-Aortic coarctation
-Aneurysm in circle of Willis
5. Never wait for cardiac enzymes in patient with STEMI
6. Congenital complete heart block carries the best prognosis
among the all causes of CHB and sometimes can be
managed conservatively for years
7. Always check for BP equality on both sides in patient with
acute Coronary syndromes to exclude dissection
8. Always ask about history of sildenafil use before using
nitrates
9. Never use sublingual Nifedipine
10.Do not diagnose Rheumatic fever based on arthralgia that is
associated with elevated ESR , You should use modified
Jones criteria

30. 29
Cardiology pearls (Part IV(
1. Diagnosis of DM:
-FBS more or equal to 126 mg/dl in two separate occasions
Or
-Postprandial blood glucose more or equal to 200mg /dl on
two separate occasions
Or
-HbA1c is more or equal to 6.5%

-Pleural fluid protein/serum protein more than 0.5
-Pleural Fluid LDH/Serum LDH more than 0.6
-Pleural fluid LDH more than 2/3 of the upper normal value
for the serum LDH
One criteria is sufficient to diagnose exudate, and all the three
criteria must be negative to say that it is transudate
4. The most common cause of convulsions in elderly is stroke
5. Unilateral Horner syndrome with ipsilateral neck pain is
suggestive of Carotid dissection until proved other wise
6. Mitral valve prolapse should diagnosed only in Parasternal
long axis view not apical 4chamber view

31. 30
7. Drop out of the interatrial septum in Apical 4 chamber is not
suggestive of ASD except after confirmation with color flow
across and further assessment in subcostal view
8. Dynamic LVOT obstruction with significant LVOT gradient
could be seen in elderly dehydrated tachycardiac patients
(especially if hypertensive with LVH and small LV cavity( .
After rehydration and control of HR, The gradient across the
LVOT disappear
9. Verapamil increase the digitalis toxicity and it is better to
combine Diltiazem rather than verapamil with digitalis
10. Digoxin toxicity can occur despite of normal digoxin level
and can be diagnosed only based on clinical basis and ECG

32. 31
Cardiology pearls (Part V(
1. ACE inhibitors can be considered for all patients with CAD if no
contraindications
2. In patients with CHF and there is contraindication for ACE
inhibitors, you can give instead: Hydralazine (Arteriolar dilator)
with isosorbide dinitrate (venodilator(
3. Spironolactone should be given for patients with resistant
hypertension as it act as aldosterone antagonist
4. Spironolactone should be given for patients with right sided HF
(congestive hepatomegaly and Ascites ) as one of the mechanisms
of fluid retention in these patients is failure of the liver to
metabolize the aldosterone , so we give anti aldosterone
5. Enoxaparin should not be given for pregnant women with
prosthesis without monitoring of antifactor X level
6. Lidocaine and phenytoin are the antiarrhythmic drugs of choice in
patients with ventricular arrhythmia secondary to digitalis toxicity
7. Causes of Bidirectional VT are CPVT and digitalis toxicity

Cardiology pearls (part VI(
1. As regard second degree heart block, there is a distinct subtype
called 2:1AV block , Can be either Mobitz type I or type II
-If it improves with atropine and narrow complex,
Most probably it is type I
-If it worsens with atropine or wide complex,
Most probably it is type II
2. Reciprocal ST depression in I and AVL may precedes frank ST
elevation in Inferior MI
3. To diagnose MI in paced rhythm with LBBB morphology, we
apply sgarbossa criteria
4. Anteroseptal STEMI and isolated RV infarction both can causing
ST elevation from V1-V3, But the difference is
- If the ST elevation is maximum in V1 and decreases gradually to
V3, then it is RV infarction
-If the ST elevation is gradually increasing towards V3, then it is
anteroseptal MI
5. -To differentiate Course AF from Atrial flutter with variable block,
You should notice that the flutter waves are identically the same
morphology, so if the atrial activity waves are different, then it is
course AF
6. -In Echocardiography, we assess pericardial effusion in diastole (as
regards measurement(
7. In patient with Interatrial septal aneurysm, you should exclude
PFO
8. Central venous pressure is a poor indicator of volume status and we
should IVC collapsibility index better
9. In assessment of Aortic prosthesis, Dimensionless velocity index is
a useful tool , (LVOT VTI/Aortic VTI) if this ratio is Lee than 0.25
it denote significant stenosis
10.In assessment of mitral prosthesis , MV VTI/LVOT VTI
If this ratio more than 2.5, it denote significant stenosis

Q: Myocardial injury vs. Myocardial
infarction?
-The term myocardial injury should be used when there is evidence of
elevated cardiac troponin values (cTn) with at least one value above the
99th percentile upper reference limit , The myocardial injury is
considered acute if there is a rise and/or fall of cTn values.
-The term acute myocardial infarction should be used when there is acute
myocardial injury with clinical evidence of acute myocardial ischaemia
and with detection of a rise and/or fall of cTn values with at least one
value above the 99th percentile and at least one of the following:
- Symptoms of myocardial ischaemia
- New ischaemic ECG changes
- Development of pathological Q waves
- Imaging evidence of new loss of viable myocardium or new
regional wall motion abnormality in a pattern consistent with an
ischaemic aetiology
- Identification of a coronary thrombus by angiography or autopsy

Case scenario to explain myocardial injury vs.
myocardial infarction
You have been consulted to review a 35 year old male patient, chronic
kidney disease on regular dialysis, hypertension, and blood pressure
160/100.
The resident in charge consulted you as he found that his troponin is
positive. ECG was normal apart from LVH with non- specific ST-T wave
changes. Cardiac wise, the patient is asymptomatic.
How will you proceed?
My approach (according to the ESC guidelines for fourth universal
definition of MI, 2018)
Few steps
1-Positive cardiac biomarker is considered cardiac injury VS. Myocardial
infarction
2-If cardiac biomarker is only positive with no evidence of ischemia by
symptoms; ECG changes; Echo, then it will be considered myocardial
injury
3-Myocardial injury is 2 types: Acute or chronic
4-To differentiate between both, you should ask for second set
If there is at least 20% change, then it is acute injury
If no change or change less than 20%
Then It is Chronic injury
Back to our case
The only available data are symptoms, ECG and one set of enzymes
The best approach is
1-Serial ECG
2-Second set troponin
3-Echo
The investigations were done and showed
1-No significant change of cardiac troponin after 6 hours
2-Echo: hypertensive heart diseases
3-No dynamic ECG changes
Final diagnosis:
Chronic myocardial injury secondary to uremic toxins and hypertension
Management:
BP control, proper management of the renal condition

Answer: Metformin
Q: Why Statin can decrease triglycerides only when it is
below 500 while it is in-effective when TG exceeds 500?
Answer:
1. If the triglycerides level below 500:
The main lipoprotein carrier for triglycerides is VLDL
Statin can reduces VLDL and it is preferred due to pleotropic
effects and mortality benefits of Statin
2. -While if triglycerides are above 500, The main lipoprotein
carrier is chylomicron, Statin cannot reduce chylomicron
So you have to give fibrates and omega 3
Q: Can we see occasional P waves in patients with
