2. Anterior heart pain: the heart is mainly supplied by the coronary arteries, when coronary artery sclerosis or spasm, etc., will be due to insufficient blood supply from the coronary arteries leading to myocardial ischemia, anterior heart pain, and when myocardial oxygen consumption is increased, the symptoms of pain will also occur.
3. Difficulty in breathing: heart disease is serious to a certain extent will lead to heart failure, resulting in patients with symptoms of dyspnea, mainly due to the decline in the contractility of the heart muscle, affecting the pulmonary circulation of blood, so that the blood in the lungs stagnation.
