3. INTRODUCTION
Heart is the pump that supplies oxygenated blood to
the various organ. Any defect in the heart
immediately affects the all other organs of the body.
Atherosclerosis is the condition which is
responsible for coronary artery disease or ischemic
disease.
24. Ischemic heart disease
A term that describes the effect of a reduction or
complete obstruction of the blood flow & oxygen
transportation through the coronary arteries.
Narrowing occurs as a result of plaque formation
or narrowing of the arteries.
25. definition
IHD is a condition in which there is an adequate
supply of blood & oxygen to a portion of the
myocardium. It typically occurs when there is an
imbalance between myocardial oxygen supply &
demand.
26. Incidence
More common cause of mortality & morbidity.
In US more than 13 mil. People are the sufferers
of IHD.
> 6 mil have angina.
>7 mil have MI.
31. ANGINA PECTORIS:-
Angina pectoris commonly known as angina the
sensation of chest pain , pressure or squeezing on
chest due to ischemia of heart muscle.
The term is derived from the Latin ‘ANGERE’
meaning to strangle & ‘PECTUS’ meaning chest
& therefore can be translated as strangling feeling
in chest.
32. Common risk factors
Exacerbating causes of
angina:-
a. Profound anemia
b. Uncontrolled HTN
c. Hyperthyroidism
d. hypoxemia
Medical problems
a. Tachyarrhythmia
b. Brady arrhythmia
c. Valvular heart disease
d. Hypertrophic
cardiomyopathy
34. Stable angina:-
Also known as effort
angina refers to classic
type of angina related
to myocardial
ischemia.
Symptoms several min
after & recur where &
when activity resumes.
Unstable angina:-
It causes unexpected
chest pain & usually
occurs while resting.
most common cause is
reduced blood flow due
to an atherosclerotic
plaque.
35. CARDIACSYNDNROME X
It is sometime known as micro-vascular
angina & is characterized by angina like
chest pain.
Primary cause is unknown but factors
endothelial dysfunction are likely to be
involved in the
37. DEFINITION
AMI also known as heart attack occurs
when blood flow stops to a part of heart
causing damage to a heart muscle
which is characterized by chest pain or
discomfort which may travel into
shoulder , arm, back, neck or jaw.
38. TYPES
THE EUROPEAN HEART JOURNALM
& THE JOURNAL OF AMERICAN
COLLEGE OF CARDIOLOGY ALONG
WITH A 2007 CONSENSUS PUBLISHED A NEW
DEFINITION OF MI WHICH DESCRIBES 5
TYPES OF ACUTE MI
40. ICD 10 codes
121 Acute MI
121.0 Acute transmural MI of ant
wall
121.1 Acute transmural MI of
inferior wall
121.2 Acute transmural MI of other
sites
121.3 Acute transmural MI of
unspecified sites
121.9 Acute MI unspecified
41. PATHOLOGICAL TYPE
1. TRANSMURAL AMI
2. SUBENDOCARDIAL AMI
3. TRANSMURAL AMI:-
Involves major coronary artery
Sub classifications are-
a. Ant MI d. Lateral MI
b. Post MI e. Septal MI
c. Inferior MI
42. 2. SUBENDOCARDIAL AMI:-
Involves small area in sub- endocardial wall of LV
septum, papillary muscle (more susceptible to
ischemia)
