THE ESSENCE OF DIAGNOSIS OF ANGINA PECTORIS
• Tightness or pressure as pain, retrosternal or easy to left (“heart hurts”). Occurs quickly during exertion, can extend and lose after the break.
• After light exercise in 70% of patients abnormal ECG is diagnosed, others 30% have a normal ECG.
GENERAL DISCUSSION OF ANGINA PECTORIS
Angina pectoris is usually caused by arteriosclerotic heart disease, but in some cases there is no significant coronary artery disease and angina pectoris is a result of severe aortic stenosis or insufficiency, increased metabolism, as is the case with hyperthyroidism or after thyroid treatment, indicated anemia and tachycardia with a rapid ventricular beats. The essence of the mechanism is in the discrepancy between requirements of myocardial in oxygen and the amount passed through the coronary arteries.
