The occurrence of cardiovascular disease can cause a series of heart and vascular lesions, in addition to palpitations, precordial pain and other obvious symptoms, there are some skin, limbs, respiratory signs on the body surface in the early stages of cardiac pathogenesis, understanding these signs, help the early diagnosis of cardiovascular disease. If one or several fingers (toes) experience the process of changing from white to purple to red, it is a typical symptom of Raynaud’s syndrome. Starting from the finger (toe) artery, to the capillaries and small veins, spasm or functional occlusion occurs successively, thus the local skin is pale. In thrombo-occlusive vasculitis, the patient’s skin is mildly flushed in the early stages and may become pale or cyanotic as the disease progresses. When vasospasm occurs, the affected limb may be suddenly and severely painful, and the skin is cold and pale. If the face is dark red, it may be suffering from rheumatic heart disease or mitral stenosis, said the doctor. If it is pale, it may be a sign of mitral valve closure insufficiency. When the face is gray and purple, the expression is indifferent, or the symptoms of advanced heart disease, need to pay attention to treatment. 2. Breathing Difficulty and shortness of breath are usually the first signs of a series of heart attacks. When doing some light activities or in a quiet state, if shortness of breath occurs, but not with coughing or coughing, this is likely to be a sign of left heart insufficiency. Usually when the heart is not functioning well, blood and oxygen cannot be delivered to the heart well, which leads to breathing difficulties. 3. Ears Heart patients have varying degrees of tinnitus in the early stages. In addition, if a coherent fold appears in the earlobe, it is most likely due to coronary artery sclerosis; if a tendon as thick as a pinky finger is raised from the clavicle to the earlobe, it is likely to be a precursor of right heart insufficiency. 4. Extremities When middle-aged and elderly people suffer from heart disease, they often have edema in the lower extremities, which is a manifestation of obstructed venous blood return due to cardiac insufficiency. In addition, the ends of the fingers or toes are obviously thick and the nail surface is raised like a drumstick, which is common in patients with chronic pulmonary heart disease or cyanotic congenital heart disease. Special reminder: If the above-mentioned physical features appear and persist, you should pay some attention to them and go to the hospital for examination in time. Early symptoms on the body surface can be helpful in the diagnosis of cardiovascular disease, but further hospital visits are needed to confirm the diagnosis.
