Ischemic heart disease/repetitorium

Myocardial blood supply disorders
Important terms: anatomy of the coronary arteries, regulation of blood flow.


 * Causes
 * 1) Increasing coronary artery resistance
 * 2) * Functional: vasoconstriction
 * shortening of diastole
 * 1) * Anatomical: thickening of the vessel wall (atherosclerosis)
 * thrombi, emboli
 * 1) * Combination of both
 * 2) Decrease in driving pressure: drop in (diastolic) BP in the aorta
 * increase in right atrial pressure


 * Vasodilator treatment – stealing phenomenon
 * Invasive treatment

Ischemic heart disease (IHD)

 * Causes: Limited blood flow in coronary vessels
 * Consequences of ischemia: impaired contractility, arrhythmia, angina pectoris, necrosis
 * Manifestations of myocardial ischemia on EKG
 * Biochemical manifestations of ischemia


 * Symptoms:
 * 1) Angina pectoris'
 * 2) * Stable
 * 3) * Unstable
 * 4) * Prinzmetal's
 * 5) Heart-attack
 * 6) * Subjective symptoms
 * 7) * ECG: T inversion, ST elevation, deep Q
 * 8) * Biochemical tests in acute myocardial infarction
 * 9) * Possibly sudden death


 * Principles of treatment and prevention
