Study Notes
Definition of Ischemic Heart Disease (IHD)
- IHD refers to a group of related syndromes caused by an imbalance between oxygenated blood supply and myocardial demands.
- Major syndromes include:
- Angina pectoris
- Myocardial infarction (MI)
- Chronic ischemic heart disease (IHD)
- Sudden cardiac death (SCD)
Incidence of IHD
- Age is a significant factor; risk increases notably after 40 years.
- Gender-related differences; males are at higher risk than females, attributed to estrogen's protective effects in women during reproductive years.
Causes of IHD
-
Coronary artery atherosclerosis:
- Primary cause leading to narrowing of coronary arteries due to plaque build-up.
-
Other causes include:
- Emboli
- Vasculitis
- Coronary spasm
- Anemia
- Shock
- Tachycardia
Pathophysiology of IHD
- Significant coronary artery disease occurs when coronary lumen obstruction exceeds 75%.
- This leads to symptomatic ischemia during exertion, commonly manifesting as angina pectoris.
