Cardiovascular medicine looks at diseases of the circulatory system, including hypertension, heart failure, arrhythmias, coronary heart disease, cardiomyopathy, and heart valve disease. Cardiovascular medicine belongs to a branch of the internal medicine system that deals with the circulatory system, including diseases caused by abnormalities in the structure and function of the heart and its vascular nerves. Heart failure is a structural or functional disease of the heart that leads to a decrease in the pumping function of the heart, which is unable to meet the metabolic needs of the organism and triggers insufficient blood perfusion to the tissues. Arrhythmia is a disease caused by abnormalities in the frequency, rhythm, pacing site, and conduction rate of the heartbeat. Coronary heart disease is a disease caused by atherosclerosis of the coronary arteries, resulting in narrowing or blockage of the coronary arteries. Cardiomyopathy is a disease caused by mechanical and/or electrical dysfunction of the heart, often characterized by hypertrophy or dilatation of the ventricles. Heart valve disease is a disease caused by narrowing and/or incomplete closure of the heart valves. Cardiovascular medicine involves more diseases, if you have heart discomfort, panic, chest pain and other symptoms, it is recommended to seek timely medical treatment, standardized treatment.
