Thyroid gland diseases directly alter the normal functioning of the heart causing significant complications. Muscular chambers which are present in heart contract and cause circulation of blood around the body.

Blood circulates normally in one direction because of valves with in your heart. Through veins, blood returns to the heart. Right ventricle and right atrium of the heart pump the blood into the lungs. Blood returns from the lungs to left ventricle and left atrium from which it is ejected into the arteries. Arteries distribute blood to various parts of the body.

Thyroxine, which is released from thyroid gland, in increased levels stimulates the heart to beat more strongly and quickly. If the fast heart rate becomes severe, then palpitations can be observed. It is sometimes noticed by normal people and can be caused by too much exercise or drinking to much caffeine.

Today is world heart day. It is celebrated annually on the last Sunday of September. World heart day encourages awareness of healthy heart. Heart disease and stroke are the world’s largest causes, claiming millions of lives every year.

World heart day began in 1999 in an effort to create awareness and educate risk factors for heart disease and stroke in the public to promote preventive measures. World heart day activities include public talks, free screenings, walks, runs, fitness events, scientific forums and exhibitions.

The theme of the world heart day is to “Team Up For Healthy Hearts”. The aim of this day is to encourage people to join together and create heart-healthy communities.

Role of heart in daily life is: physically it beats 70 times per minute and plays an important role in body functions and mentally, it shows kindness, generosity and sympathy in nature.

The causes of heart diseases and stroke in people include obesity, cigarette smoking and food habits. Lack of physical activity and improper diet can lead to obesity and it in turn increases the chances of heart disease. Intake of fatty and junk foods in large quantities also increases the risk of heart failures.

Heart attack is the leading cause of death of men and women in United States. Heart attack is a permanent damage to the heart muscle. There are many risk factors associated with heart attack. Know and identify the risk factors associated with heart attacks to prevent before you become a victim [Prevent heart disease risk factors].

Risk factors associated with heart attack:

Smoking and heart attack:

Smoking is a major cause of heart attack. Smoking damages heart and blood vessels.

Most heart attacks are caused by atherosclerosis. Atherosclerosis is a condition in which the arteries become hard and clogged.

Clogged arteries prevent in getting enough blood and oxygen to the heart and can cause chest pain or angina.

When a blood clot is formed, it cuts off the blood flow suddenly in the artery and cause heart attack.

Smoking speeds up the process of atherosclerosis by damaging the cells lining the blood vessels and heart. Smoking increases the risk of blood clots because of atherosclerosis and it also causes the blood platelets to clump together.

Heart stopping news for women:

Estrogen hormone provides some protection in women from heart disease. Therefore, most women have heart attacks after menopause, especially ten years after menopause due to the decrease of estrogen in their body.

Congenital Heart Disease (CHD), also known as congenital heart defects, is a type of heart disease that occurs in newborns.

This condition results from the structural defects of the heart or the major blood vessels close to the heart during the pregnancy, before the baby’s birth.

Heart, an essential part of the body, is a hollow muscular organ that is responsible for the blood circulation throughout the body.

The blood is circulated all over the body through tubes called blood vessels.

Congenital heart disease is also known as cyanotic heart disease or congenital cardiovascular malformations. It is one of the most common types of birth defects in infants. It is found that eight out of every thousand newborns, in the United States, are affecting with CHD. Yearly, over thirty-five thousand babies are born with congenital heart disease.

The congenital heart disease or defects of the heart takes place during the first eight weeks of the pregnancy. This condition is usually recognized within one week from the childbirth.

Congenital heart diseases are of several types. The types range from trouble-free defects with no signs to very complex defects with severe and life-threatening signs. Most of these types block the blood circulation in the heart or the vessels near the heart, or allow an unusual flow of blood through the heart.

Hypertension of high blood pressure increases the risk of heart failure.

The risk of heart failure is two times higher in men and three times higher in women than in people with normal blood pressure levels.

When heart loses the ability to pump enough blood throughout the body, heart failure occurs.

The heart failure severity depends on how much pumping capacity is lost. High blood pressure is a major factor that contributes to the risk of heart disease. When high blood pressure is left untreated, it will cause the heart to overwork itself to the point where serious damage can occur.

Hypertension leads to stiffened or hardened arteries that causes reduced blood flow to the heart muscle and other parts of the body. Angina, which means chest pain or damage to the heart muscle due to lack of blood carrying oxygen to the heart muscle can result due to reduced blood to the heart muscle. Reduced blood to the heart muscle also leads to heart attack, which is caused by chronic spasm or blood blockage and oxygen to the heart.
