Possible causes of cardiac distress in the elderly include coronary artery disease, arrhythmia, and heart failure. 1. Heart failure: the most common clinicopathologic change in the elderly. Various causes of heart disease will eventually develop into heart failure, causing a decline in cardiac contraction and a decrease in the volume of blood circulating in the body, which in turn leads to cardiac distress. 2. Coronary heart disease: angina pectoris, myocardial infarction and other coronary atherosclerotic heart disease can cause patients with different symptoms of heart discomfort, such as palpitations, severe chest pain, discomfort in the precordial area, chest pressure. 3. Arrhythmia: Various kinds of tachyarrhythmia can lead to tachycardia and cardiac symptoms; slow arrhythmia due to the prolongation of diastolic period, ventricular filling increase and enhancement of the beat, there will be palpitations and other symptoms. Sick sinus node syndrome, atrioventricular block, atrial fibrillation, etc. can also cause cardiac discomfort or a sense of stoppage due to irregular or intermittent heartbeats. In addition to the above reasons, elderly people may also have cardiomyopathy, heart valve disease, pericardial effusion, adrenal pheochromocytoma, hyperthyroidism, biliary tract diseases, etc. It is recommended that patients go to the hospital as soon as possible to find out the cause of the disease and then be treated accordingly.
