What diagnosis is indicated by significant distress and pain after physical activity in an older patient with known risk factors?

The diagnosis of angina pectoris is indicated by significant distress and pain after physical activity, especially in older patients with known risk factors such as hypertension, hyperlipidemia, diabetes, or a history of smoking. Angina pectoris occurs due to the inadequate blood flow to the heart muscle, typically caused by coronary artery disease. During physical exertion, the demand for oxygen increases, and if the coronary arteries are narrowed, patients may experience chest pain or discomfort, which is a classic presentation of angina.

The symptoms of angina often improve with rest or with the use of nitroglycerin, as these actions decrease myocardial oxygen demand and increase blood flow to the heart. In older patients, who may have an increased prevalence of cardiovascular disease, recognizing the signs of angina is crucial for timely intervention and management.

The other potential conditions would present differently or be associated with distinct symptoms that may not be as clearly linked to physical activity and the typical risk factors for coronary artery disease.
