Pre-exertional prophylaxis of anginal pain

Pre-exertional prophylaxis of anginal pain refers to the preemptive clinical management of predictable episodes of myocardial ischemia precipitated by anticipated physical exertion or emotional stress Pre-exertional prophylaxis aims to preserve the balance between myocardial oxygen supply and demand immediately prior to high-demand activities, thereby preventing the onset of ischemic symptoms

This condition primarily affects the cardiovascular system in individuals with underlying coronary artery disease or chronic stable angina, where fixed atherosclerotic stenosis limits coronary blood flow Pathophysiologically, heightened physical effort abruptly increases myocardial oxygen consumption through elevations in heart rate, blood pressure, and left ventricular wall tension, outpacing limited coronary oxygen delivery and triggering retrosternal pressure, tightness, or pain Pre-exertiona...
