Myocarditis is an inflammatory disease of the heart muscle that can be caused by infectious or non-infectious triggers. It has a variable clinical presentation ranging from mild symptoms to life-threatening conditions. The diagnosis is challenging due to the heterogeneity of symptoms but can involve electrocardiogram, cardiac biomarkers, echocardiogram, cardiac MRI and endomyocardial biopsy. About half of acute cases resolve in 2-4 weeks but some develop heart failure or arrhythmias. Treatment focuses on supporting heart function and managing symptoms while the disease runs its course.
This document defines heart failure and discusses its key characteristics. It describes how heart failure occurs when the heart is unable to pump enough blood to meet the body's needs due to problems like abnormal heart muscle function or excessive loads on the heart. The document outlines the pathophysiology and progression of heart failure, including ventricular dilation and hypertrophy as compensatory mechanisms that ultimately fail. It also covers the clinical features, diagnostic tests, medical management, and nursing care considerations for patients with heart failure.
An aortic aneurysm is a localized sac or dilation formed at a weak point in the aortic wall. They most commonly occur in the abdominal aorta and can be caused by conditions like hypertension, atherosclerosis, and smoking. Aortic aneurysms are classified as either saccular or fusiform based on their shape and size. Untreated aneurysms risk rupture, which can cause massive hemorrhage and death. Surgical treatment involves replacing the diseased aortic segment with a synthetic graft to prevent rupture.
This document discusses ischemic heart disease and coronary artery disease. Coronary artery disease is caused by atherosclerosis which develops due to risk factors like smoking, high blood pressure, high cholesterol, and diabetes.

Arrhythmogenic right ventricular cardiomyopathy primarily affects the right ventricle and can cause arrhythmias or sudden death.
Heart failure is a condition where the heart cannot pump enough blood to meet the body's needs. It has many potential causes, but is often due to problems with the heart muscle itself or valves. Treatment focuses on managing symptoms with diuretics, and slowing progression with ACE inhibitors, beta-blockers, and aldosterone antagonists. Other therapies aim to improve heart function or treat underlying causes. Prognosis depends on severity but ranges from 5-50% annual mortality.

Angina pectoris, also known as angina, is a clinical syndrome characterized by chest pain or discomfort due to reduced blood flow to the heart muscle. The reduced blood flow results in decreased oxygen supply to the heart in response to physical or emotional stress. Angina is caused by coronary artery disease which can result from atherosclerosis, spasm, blood clots, or other conditions. Risk factors include increasing age, family history, hypertension, smoking, and high cholesterol. Treatment involves lifestyle changes, medications to reduce symptoms and risk factors, and sometimes surgical procedures like stenting or bypass surgery.

Lifestyle changes such as quitting smoking, diet, exercise, and weight control also help manage the disease.
Coronary artery disease (CAD) is the most common type of cardiovascular disease. It is caused by plaque buildup in the coronary arteries that supply blood to the heart. This restricts blood flow and oxygen supply to heart muscle. Symptoms include chest pain and discomfort known as angina. Diagnosis involves electrocardiograms, stress tests, imaging like angiography and echocardiograms. Treatment focuses on lifestyle changes and medications to control symptoms and risk factors as well as procedures like angioplasty and stents to open blocked arteries. High dose thiamine injections showed promise in curing CAD in one research study. Proper management can help cure angina and allow those with CAD to live long, productive lives

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

2. ISCHEMIC HEART DISEASE
• Definition:
• Ischemic heart disease (IHD) is a condition in which there is inadequate supply of
blood and oxygen to a portion of myocardium. It tipically occurs when there is an
imbalance between myocardial oxygen supply and demand.
• It’s the most common, serious, chronic, life-theatening disease in the developed
countries.
• The most common cause is atherosclerotic disease of an epicardial coronary artery.
3. PATHOPHYSIOLOGY OF MYOCARDIAL ISCHEMIA
• Myocardial oxygen supply is decreased
• Narrowed coronary arteries (sclerosis, thrombus, spasmus, coronary embolism,
vasculitis)
• Hypotension
• Severe anemia
• Methemoglobinemia, increased carboxyhemoglobin
• Myocardial oxygen demand is increased
• Left ventricle hypertrophy
• Fever
• Hyperthyroidism
• Tachycardia
15. CLINICAL PICTURE OF IHD IS DIVIDED IN TO
TWO GROUPS:
1. Chronic ischemic heart diseases:
A: Stable angina .
B: Silent myocardial ischemia .
C: Variant or vasospastic angina.
2. Acute coronary syndrome ( ACS ):
a) Unstable angina
b) NSTEMI.
c) STEMI .
17. Silent myocardial ischemia ( no chest pain):
• In elderly patient.
• In diabetic patient.
• In female.
18. Variant or vasospastic angina:
• Vasospasm is present .
• Mostly at night .
• In the absent or present of stenosis.
• Clinical presentation:
- Chest pain .
• ECG:
- ST segment elevation or depression .
19.
20. SUMMARY OF THE CHARACTERISTICS OF
ANGINA PECTORIS
• Typical angina pectoris:
• Retrosternal chest pain (discomfort)
• Complaints occur after exertion or emotional stress
• The pain is relieved by rest and nitroglycerin
• Atypical angina pectoris: only two from three characteristics (especially in
women and diabetics, angina may be atypical in location and not strictly
related to provocing factors)
• Pseudoangina: Only one or no one out of three characteristics.
26. • Beta blocker :
- β₁ receptors( In the heart ).
- β₂ receptors (In bronchus and smooth muscles of vessels ).
- Beta blocker decreased sympathetic activity and reduced the oxygen
consumption of the heart.
27. • Calcium channel blocker (CCB) :
- It is used for variant angina or prenzmintal angina .
- Induce vasodilation in coronary and peripheral vessels .
• Nitroglycerine and nitrates( Isosorbide dinitrate and Isosorbide
mononitrate ):
- Dilate the vessels .
- Decreased preload and afterload .
- Antiplatelet effect .
