Any heart attack could potentially mean the onset.
myocardial infarction. Vital functions of all internal organs, including
including the heart, is provided with blood circulation.
Blood vessels and blood is a transport system that
supplies tissues with oxygen, nutrients and building
materials, and also displays decomposition products.

heart attack. With the increase in the weight of the patient, the body occurs

deposited not only in the subcutaneous fat and abdominal
glands, but also on the surface of the heart, which can provoke
mechanical pressure on the coronary arteries.
|Alcohol abuse||Increases blood pressure, constant intoxication

|Smoking||Nicotine significantly reduces the level of oxygen in the blood, forming
pathological compounds with hemoglobin, while the level

attention that there is an external feature – a diagonal fold

his legs, after 1-2 minutes.
- If a patient has a heavy, noisy, bubbling breath, he cannot
stack, as this will aggravate the condition. Such a patient
need to sit down comfortably and securely.
First aid in the ambulance
