Chapter 34: Common Cardiovascular Complaints

Common Cardiovascular Complaints systematically examines six cardinal cardiovascular complaints encountered in primary care practice and establishes frameworks for distinguishing between benign and pathological etiologies. Chest pain assessment requires detailed characterization of symptom quality, duration, and modifying factors, with recognition that ischemic presentations may manifest as tightness or fullness rather than pain itself. Angina pectoris typically manifests as brief retrosternal discomfort lasting 1 to 10 minutes, whereas acute myocardial infarction produces prolonged symptoms exceeding 20 minutes and frequently includes dyspnea, diaphoresis, nausea, and radiation to the jaw or arms; atypical presentations in women, older adults, and diabetic patients necessitate heightened clinical suspicion. Palpitations reflect patient awareness of cardiac rhythm and warrant investigation for thyroid dysfunction, electrolyte abnormalities, anemia, and arrhythmias including atrial fibrillation, the most prevalent sustained rhythm disturbance. Syncope represents a critical symptom indicating abrupt loss of consciousness from severely reduced cerebral perfusion, with cardiac causes such as arrhythmias and outflow obstruction carrying elevated mortality risk, distinguishable from noncardiac etiologies through careful history and diagnostic testing. Dyspnea functions as both a direct cardiac symptom and anginal equivalent in vulnerable populations, with orthopnea and paroxysmal nocturnal dyspnea serving as hallmark indicators of heart failure pathology. Peripheral vascular disease manifesting as leg discomfort requires differentiation between arterial insufficiency from atherosclerotic disease and venous compromise from valvular dysfunction or chronic insufficiency. Peripheral edema in dependent extremities demands systematic investigation to identify underlying causes including cardiac decompensation, venous disease, renal dysfunction, hepatic disease, or medication-induced fluid retention, with appropriate diagnostic evaluation incorporating laboratory studies and imaging modalities to prevent tissue ischemic complications and guide targeted management strategies.
