What is the pain in the left side of the back, chest and shoulder?

When people exercise, they must protect themselves and not overdo it. Moderate exercise is very beneficial to the health of the body. But what is causing the pain in the left side of my back, chest and shoulder? This is a question many people want to know. Back pain is often related to improper exercise, while chest pain needs to be distinguished as muscle pain or heart pain, and one should be more alert to the occurrence of coronary heart disease.

Ten major causes of coronary heart disease

If we want to cure coronary heart disease, we must first analyze what causes it. Only when we find the cause can we have a better treatment method. After research, it was found that the main causes of coronary heart disease are as follows:

1. Age-related

The main group of people affected by coronary heart disease are middle-aged and elderly people over 40 years old. The disease progresses faster after the age of 49. However, in recent years, the incidence of coronary heart disease has tended to become younger.

2. Gender-related

Among multiple races in the United States, the coronary heart disease mortality rate among men is significantly higher than that among women. In our country, the male-to-female ratio is about 2:1. However, after menopause, the incidence of coronary heart disease has a clear upward trend due to the significant decrease in estrogen levels. Relevant treatments have shown that women over 60 have more coronary heart disease than men.

3. Occupation-related

Those who do mental labor generally outnumber those who do physical labor because they are under a long-term sense of oppression.

4. Diet-related

People who often eat high-calorie diets, more animal fat and cholesterol are prone to this disease; therefore, to control the incidence of coronary heart disease, in addition to controlling the intake of high-fat diets, it is also necessary to pay attention to controlling food intake.

5. Related to obesity

Obese people who exceed the standard weight are prone to coronary heart disease, especially those who gain weight rapidly. However, it is currently believed that more attention should be paid to studying methods for evaluating body weight. Don't just look at the body mass index, but measure the thickness of subcutaneous fat. Existing prospective research data show that people with central obesity are at greater risk.

6. Related to blood pressure

Increased blood pressure is an independent risk factor for coronary heart disease. The harm caused by atherosclerosis due to high blood pressure is 4 times that of patients with hypertension as compared to those with normal blood pressure.

7. Related to smoking

Smoking is the main risk factor for coronary heart disease. Compared with non-smokers, the incidence and mortality of this disease in smokers are 2 to 6 times higher, and are directly proportional to the number of cigarettes smoked per day.

8. Related to blood lipids

Dyslipidemia is caused by genetic factors, excessive fat intake, or lipid metabolism disorders. If total cholesterol, triglycerides, LDL, and VLDL increase, while HDL decreases, one is prone to this disease.

9. Related to diabetes

It is generally acknowledged that diabetes mellitus is susceptible to cardiovascular disease. Data show that the incidence of this disease in diabetic patients is twice that of non-diabetic patients.

10. Related to genetics

If there is someone in the family who is prone to this disease at a young age, the chance of his or her close relatives suffering from the disease may be five times that of a family without this condition.

Clinically, coronary heart disease is divided into five types: latent type, angina pectoris type, myocardial infarction type, heart failure type (ischemic cardiomyopathy), and sudden death type. The most common type is angina pectoris, and the most serious types are myocardial infarction and sudden death. Let’s learn about the classification of coronary heart disease.

Coronary heart disease classification

1. Hidden type

The patient has coronary artery sclerosis, but the lesions are mild or have better collateral circulation, or the patient has a high pain threshold and therefore has no pain symptoms.

2. Angina pectoris

A clinical syndrome of acute and transient myocardial ischemia and hypoxia caused by increased myocardial load on the basis of coronary artery stenosis.

3. Myocardial infarction

On the basis of coronary artery lesions, the coronary blood supply is sharply reduced or interrupted, causing severe and persistent acute ischemia of the corresponding myocardium and leading to myocardial necrosis.

4. Heart failure

(Ischemic cardiomyopathy) Myocardial fibrosis, long-term insufficient blood supply to the myocardium, nutritional disorders and atrophy of the myocardial tissue, or after a large area of ​​myocardial infarction, resulting in proliferation of fibrous tissue.

5. Sudden death

The patient's cardiac arrest occurs due to coronary artery spasm or embolism on the basis of atherosclerosis, which leads to acute myocardial ischemia, local electrophysiological disorders, and temporary severe arrhythmias.

If we want to stay away from coronary heart disease, we should have good living habits and have regular physical examinations to achieve early detection and early treatment. For those who engage in mental work for a long time, we must learn to relax appropriately and not put ourselves under long-term stress.
