Which of the following symptoms may indicate the patient is experiencing a cardiac issue? SELECT ALL THAT APPLY.

A. Fatigue: Reduced cardiac output limits oxygen delivery to tissues, leading to generalized fatigue and decreased exercise tolerance. This is a common presenting symptom in heart failure and other cardiac conditions, especially in older adults. B. Chest pain: Chest pain is a classic symptom of myocardial ischemia and other cardiac events. It results from inadequate coronary perfusion and may signal angina or acute coronary syndrome requiring urgent evaluation. C. Edema: Peripheral edema occurs when impaired cardiac function leads to venous congestion and fluid accumulation in dependent tissues. It is commonly seen in right-sided or advanced heart failure due to increased venous pressure. D. Bilateral tingling in feet: Tingling in the feet is more suggestive of peripheral neuropathy, electrolyte imbalance, or diabetic complications. It is not a typical manifestation of primary cardiac dysfunction.
