What are the symptoms of heart disease?

People should be very familiar with diseases in their lives. There are many factors in people's daily lives that can cause diseases in the human body. Heart disease is a typical disease. Many people are not sure whether some of their symptoms are caused by heart disease when they are sick. So, what are the symptoms of heart disease?

First, what are the symptoms of heart disease?

Coronary heart disease is the abbreviation of coronary artery heart disease, which is the most common heart disease. It refers to myocardial dysfunction and/or organic lesions caused by coronary artery stenosis and insufficient blood supply, so it is also called ischemic cardiomyopathy. Coronary heart disease is a heart disease caused by organic stenosis or blockage of the coronary arteries (atherosclerosis or dynamic vasospasm), resulting in myocardial ischemia and hypoxia (angina pectoris) or myocardial necrosis (myocardial infarction), also known as ischemic heart disease. The occurrence of coronary heart disease is closely related to the degree and number of coronary artery stenosis caused by atherosclerosis. At the same time, diseases such as hypertension, diabetes, excessive obesity, and bad living habits are the main factors that induce the disease. Coronary heart disease is one of the diseases with the highest mortality rate in the world. According to a 2011 report by the World Health Organization, the number of deaths from coronary heart disease in China ranks second in the world.

Second, angina pectoris type: manifested as a feeling of squeezing and stuffiness behind the sternum, accompanied by obvious anxiety, lasting for 3 to 5 minutes, often radiating to the left arm, shoulder, mandible, throat, back, and can also radiate to the right arm. Sometimes these parts may be involved without affecting the area behind the sternum. Angina pectoris that occurs when exertion, emotional excitement, cold, full meals, etc. increase myocardial oxygen consumption is called exertional angina, which can be relieved by rest and sublingual nitroglycerin. Sometimes angina pectoris is atypical and may present as shortness of breath, fainting, weakness, and belching, especially in the elderly. Depending on the frequency and severity of attacks, angina pectoris is divided into stable and unstable angina pectoris. Stable angina pectoris refers to exertional angina pectoris that lasts for more than one month. The site of attack, frequency, severity, duration, the amount of exertion that induces the attack, and the amount of nitroglycerin used to relieve the pain are basically stable. Unstable angina refers to an increase in the frequency, duration, and severity of the original stable angina, or a new onset of exertional angina (occurring within 1 month), or angina at rest. Unstable angina is a precursor to acute myocardial infarction, so if you find it, you should go to the hospital immediately.

What are the symptoms of heart disease? Myocardial infarction type: There are often prodromal symptoms about a week before the infarction, such as angina pectoris at rest and during slight physical activity, accompanied by obvious discomfort and fatigue. Infarction is manifested by persistent and severe pressure, stuffiness, and even knife-like pain behind the sternum, often affecting the entire chest, with the left side being more severe. In some patients, the symptoms may radiate downward along the ulnar side of the left arm, causing numbness and tingling in the left wrist, palm, and fingers. In some patients, the symptoms may radiate to the upper limbs, shoulders, neck, and mandible, mainly on the left side. The pain was located in the same area as previous angina pectoris, but it lasted longer and was more severe, and was not relieved by rest or sublingual nitroglycerin. Sometimes it manifests as upper abdominal pain, which can easily be confused with abdominal diseases. Accompanied by low fever, irritability, sweating and cold sweat, nausea, vomiting, palpitations, dizziness, extreme fatigue, difficulty breathing, and a sense of impending death, which can last for more than 30 minutes and up to several hours. If you find this happening, you should see a doctor immediately.
