What are the symptoms of insufficient blood supply to the heart?

The heart has a unique ability to circulate blood throughout the body to ensure that nutrients reach every part of the body. In order to accomplish its goals, the heart must have the support of blood, because the heart itself consumes a large amount of blood to maintain its own function. If the heart is not supplied with enough blood, it will affect the body. Let’s take a look at the symptoms of insufficient blood supply to the heart.

Heart activity requires adequate energy supply. The heart's blood supply has two notable characteristics: ① Although the weight of the heart is less than 1% of the total body weight, it requires 20% of the body's blood volume to meet the heart's own blood supply; ② In order to meet the special needs of the heart's blood supply, the human body also has its own coronary artery circulation blood supply system to ensure adequate blood supply.

Myocardial insufficiency often occurs after the age of 40, with an average prevalence of about 6.49%. Currently, the prevalence of myocardial ischemia in our country is increasing year by year. Myocardial ischemia is a common and frequently occurring disease among middle-aged and elderly people. Common symptoms include:

1. When tired or mentally stressed, dull pain or tightening pain may occur behind the sternum or in front of the heart, and radiate to the left shoulder and left upper arm. It lasts for 3 to 5 minutes and then resolves on its own after rest. In severe cases, it may be accompanied by sweating.

2. Chest tightness, palpitations, and shortness of breath occur during physical activity and are relieved on their own during rest.

3. Exercise-related sore throat, burning sensation, tightness, toothache, etc.

4. Chest pain and tightness occur after a full meal, cold weather, or drinking.

5. When the pillow is low when sleeping at night, you will feel chest tightness and shortness of breath, and you need to lie in a high pillow to feel comfortable; if you suddenly have chest pain, palpitations, and difficulty breathing when you are sleeping soundly or lying flat during the day, you need to sit up or stand up immediately to relieve the pain.

6. Feeling anxious, chest tightness, shortness of breath, or chest pain during sexual intercourse or straining to have a bowel movement.

7. Sudden bradycardia, low blood pressure or syncope.

8. There are often no symptoms in the early stages of the disease, but shortness of breath, rapid breathing and increased heart rate gradually appear. If you have paroxysmal chest pain and feel tired and weak, these are obvious symptoms of cardiovascular disease.
