In addition to palpitations, precordial pain and other familiar symptoms, heart disease often has physical signs and symptoms that can be observed to help people detect heart disease in time. These superficial signs are: Jugular varicose vein: a tendon extending from the clavicle to the earlobe, as thick as small fat, mostly caused by right heart insufficiency. Cyanosis: Cyanosis of the skin mucosa and extremities, mostly due to cardiac hypoxia and increased reduced hemoglobin in the blood. Earlobe crease: A coherent crease in the earlobe is most likely due to coronary arteriosclerosis. Mortar and pestle fingers (toes): The ends of the fingers or toes are significantly thicker and the nail surface is raised like a drumstick, commonly in patients with chronic pulmonary heart disease or congenital cyanotic heart disease. Compulsive squatting: frequent palpitations and shortness of breath, relieved only by squatting, is a characteristic manifestation of cyanotic heart disease. Perverted nose: A hard nose indicates too much fat accumulation in the heart; a swollen nose tip indicates that the heart fat may also be enlarging or that the heart lesion is expanding; a red nose is also often indicative of heart disease. Special facial features: a gray and purple face with an indifferent expression is a risky face for advanced heart disease; a dark red face is a characteristic of mitral stenosis in rheumatic heart disease; a pale face is a possible sign of mitral valve incomplete closure. Skin discoloration: The skin of patients with chronic heart failure and advanced pulmonary heart disease may be dark brown or dark purple, and the disaster is related to long-term hypoxia of body tissues and decreased function of adrenal brisket. Lower limb edema: middle-aged and elderly people have lower limb edema, which is often a manifestation of venous blood return obstruction due to cardiac insufficiency. Tinnitus: Heart patients have varying degrees of tinnitus in the early stages of the disease. This is due to abnormal microvascular dynamics in the inner ear, and the inner ear gets an aura signal before the disease causes a systemic reaction. Shoulder pain: This shoulder pain is not related to the climate and is mostly a paroxysmal pain in the left shoulder and the inner side of the left arm. According to the survey statistics, the number of coronary heart patients with shoulder pain accounts for about 65% of the patients. Snoring: Those who snore continuously for a long time have a much greater risk of heart disease than those who snore occasionally. Shortness of breath: Shortness of breath often occurs during light activity or quietness, but is not accompanied by coughing and coughing up sputum, which is likely to be a manifestation of left heart insufficiency.
