Smoking and Heart Disease

Another word used to describe a heart attack is myocardial infarction, cardiac infarction and coronary thrombosis. A heart attack is the death of a part of the heart caused by the loss of blood supply. The blood supply is usually gone due to a coronary artery being blocked by a blood clot. When a part of a heart artery breaks a blood clot forms around the piece. This blood clot can block the blood flow through the heart muscle. When the heart muscle needs oxygen it is called ischemia. When damage of a part of the heart muscle happens it’s called a heart attack. During a heart attack damage occurs depending on the size of the area blocked by the blood clot as well as the time between the actual heart attack and the treatment. Even though the heart may be hurt, the rest of the organs work with no problems. However, it will not pump as much blood as it used to in order to supply the same amount of blood to all of the parts of the body.

     Nicotine has many various effects on the body. In small doses nicotine can serves as a stimulant, entering the bloodstream and promoting the flow of adrenaline, a stimulating hormone. It also raises the blood pressure and reduces the appetite, and it may cause nausea and vomiting.

1). Another study shows that nicotine stimulates the adrenal medulla to secrete hormones such as epinephrine and norepinephrine which are responsible for the increase in the pulsation rate (George, "Effects of smoking on cardiovascular function: the role of nicotine and carbon monoxide", 2015, pp. 278-280).

A heart attack occurs when an artery that supplies blood to the heart becomes blocked. The loss of oxygen and nutrients damage the heart's muscle tissue, causing the remaining healthy tissue to pump even harder to keep up.

lives. A simple definition of a heart attack is a sudden failure of the heart

Once nicotine is in the blood stream it flows almost immediately to the brain. The carbon monoxide that is inhaled through the use of a cigarette reduces the amount of oxygen the blood can carry. The reduced amount of oxygen and the effects of nicotine delivered to the brain cause an imbalance of the amount of oxygen that is demanded and the amount of oxygen supplied. As a result of a reduced amount of oxygen in the blood stream the heart rate increases, because the heart has to increase the flow of blood to deliver the amount of oxygen that is required throughout the body. The body’s blood pressure also increases when nicotine is introduced into the body. Nicotine stimulates the adrenal gland which releases adrenalin and noradrenalin. The release of these hormones can have numerous effects on the body’s vascular system and cause an increase in blood pressure.

     Heart attack occurs when a blood clot suddenly and completely blocks a diseased coronary artery, resulting in the death of the heart muscle cells supplied by that artery. Coronary and Coronary Thrombosis 2 are terms that can refer to a heart attack. Another term, Acute Myocardial Infarction 2, means death of heart muscle due to an inadequate blood supply.

A heart attack, also known as a myocardial infarction, usually occurs when a blood clot forms inside a coronary artery at the site of an atherosclerotic plaque. The blood clot severely limits or completely cuts off blood flow to part of the heart. In a small percentage of cases, blood flow is cut off when the muscles in the artery wall contract suddenly, constricting the artery. This constriction, called vasospasm, can occur in an artery that is only slightly narrowed by atherosclerosis or even in a healthy artery. Regardless of the cause of a heart attack, the oxygen deprivation is so severe and prolonged that heart muscle cells begin to die for lack of oxygen. About 1.1 million people in the United States have a heart attack every year;

Myocardial infarction is the technical name for a heart attack, is the damage and death of heart muscle from the sudden blockage of a coronary artery by a blood clot. Coronary arteries are blood vessels that supply the heart muscle with blood and oxygen. Blockage of a coronary artery deprives the heart muscle of blood and oxygen, causing injury to the heart muscle. Injury to the heart muscle causes chest pain and chest pressure sensation. If blood flow is not restored to the heart muscle within 20 to 40 minutes, irreversible death of the heart muscle will begin to occur. Muscle continues to die for six to eight hours at which time the heart attack usually is "complete." The dead heart muscle is eventually replaced by scar tissue.

The role of smoking in Coronary Heart Disease: Inhaling tobacco smoke causes several immediate responses within the heart and its blood vessels. Within one minute of starting to smoke, the heart rate begins to rise: it may increase by as much as 30 percent during the first 10 minutes of smoking. Nicotine raises blood pressure: blood vessels constrict which forces the heart to work harder to deliver oxygen to the rest of the body. Meanwhile, carbon monoxide in tobacco smoke exerts a negative effect on the heart by reducing the blood's ability to carry oxygen (ASH, 2004).

Another cardiovascular malfunction that cigarette smoking may cause are strokes. A stroke is damage to the brain caused by leakage from a ruptured blood vessel or an interruption in blood supply. Nicotine and carbon monoxide in cigarette smoke affect the adhesives of blood platelets, the main clotting factor in blood. This can cause blood vessels to harden and form blood clots that can flow to the brain, a major cause of strokes. Nicotine can also cause the blood vessels to constrict. When a smokers arteries become too constricted,

Heart attacks , we have all seen them played out on our favorite drama shows but these shows do not address the real severity of an actual heart attack despite the great acting skills portrayed . A heart attack can also be known as a myocardial infarction (MI), acute myocardial infarction (AMI), acute coronary syndrome, coronary thrombosis, or coronary occlusion, either way it is not good news. Over 1.2 million people in American have heart attacks with many of them resulting in death (Heart attack, 2011). A heart attack is a serious life threatening condition that needs to be treated quickly.

Additionally, nicotine tightens the blood vessels which slows down blood flow. The health effects of smoking are frightfully damaging and in many cases, deadly. The chemicals in tobacco smoke are breathed in into the lungs and then travel throughout the body.

To begin with, nicotine is a stimulant drug which found in not only regular cigarette but also, electronic cigarettes. Nicotine is an highly addictive substance that effects the brain. Research has shown that nicotine in a persons body gives them a sense of pleasure. The addictiveness of nicotine in ones body causes that person to crave even more drugs. According to Elliot Antman MD, president of American Heart Association, "Nicotine is known to increase heart rate and increase blood pressure" for instance, breathing during a physical activity such as, cross-country or even volleyball, the physical activity becomes more difficult due to smoking causing your lungs

As soon as you begin to smoke, you cause immediate health risks. Within one minute of smoking, the heart rate rises significantly, as much as 30% in the first 10 minutes. Nicotine also raises blood pressure. Blood vessels constrict, forcing the heart to work harder. This makes it more difficult for the oxygenated blood to be pumped efficiently to the rest of the body. Carbon monoxide in tobacco smoke also diminishes the blood's ability to carry oxygen in the blood. It attaches itself to hemoglobin much more easily than oxygen does. Hemoglobin is what carries oxygen in the blood. Also, Smoking decreases HDL, or good cholesterol. It also increases LDL, bad cholesterol. The more
