The common symptoms of heart disease are chest pain, chest tightness, and palpitations (also called panic attacks). In addition to the above symptoms, the body surface will give out some signals as well. Usually there are signs that occur hours, days or even weeks before a heart attack. For people with a high incidence of heart disease, if you can pay attention to these “call signs”, you can have a head start on timely treatment. 1. Shortness of breath When the patient is in a quiet state or doing some light activities, shortness of breath will appear, but it will not be accompanied by coughing or coughing up phlegm. The above situation may be a manifestation of left heart insufficiency. Some patients may feel weak, and this symptom is more obvious when they move a little, but they will feel better again after resting. If you encounter this situation, you should also be alert to the causes of the heart. It may be that the heart is abnormal and cannot provide enough blood to the whole body, so it feels weak when you move around. 3. Frequent dizziness Heart disease can cause abnormal blood supply to the body, such as low oxygen levels in the blood, or abnormal blood pressure (high or low), which can cause dizziness symptoms. If patients often experience unexplained dizziness, they should also be alert to the possibility of heart disease. 4. Edema or low urine volume Decreased urine volume and edema often occur together, and it is also a distress signal for the heart. When middle-aged and elderly people have edema in the lower extremities, it is often a manifestation of obstructed venous blood return due to cardiac insufficiency. 5. Sweating profusely If a patient suddenly sweats without any obvious reason, resulting in a drenched body or a pale or gray face, this is likely to be a signal of heart abnormalities. Some patients with heart disease may have no obvious symptoms before the onset of the disease. When the above-mentioned discomfort occurs in the body, it is often not associated with heart disease and the best time for treatment is easily missed. Therefore, several of the most atypical symptoms emitted by the body mentioned in the article should draw your attention.
