Your heart is in your hands

Your heart is in your hands

Do you smoke, drink or lead a sedentary life? Do you have high blood pressure, sugar or cholesterol levels? Are you under stress due to personal or professional problems? Do you think you are suffering from Cardiovascular-Disease (CVD)? These questions are largely applicable to most people but are extremely crucial when it comes to women. 

Why? The answer lies in the exponential increase in the incidence of CVDs among women. The death rate due to cardiac disease among women has increased from 30 per cent in 1997 to 54 per cent in 2009 and the myth that heart disease is a ‘man’s disease’ has been debunked.

Underestimated

Almost half of the 17.3 million annual CVD’s deaths occur in women, though the risk is often underestimated. If you ask women about the greatest health problem they face, the majority would say breast cancer. But it is CVD, which poses the greatest health problem for women today. It claims the lives of more women than all forms of cancer combined.

Children are also at risk since they have little control over their environment and their heart-healthy choices can be limited. The other reason is Congenital heart defect (CHD). This is caused by improper development of the heart during foetal development. Mothers who do not adhere to the special diet necessary to manage the disease during pregnancy have a higher risk of having a child with congenital heart disease. 

Women with insulin-dependent diabetes may have a higher risk of having a child with heart defects. 

The most common cause of CVD is Atherosclerosis (hardening/clogging of arteries caused by the build-up of cholesterol and fatty deposits (called plaque) on the inner walls of the arteries. This restricts blood flow to the heart. 

Without adequate blood, the heart is starved of oxygen and the vital nutrients it needs to work properly. When one or more of the coronary arteries becomes blocked, a heart attack (injury to the heart muscle) can occur.

The most important challenge is to identify the symptoms in women because these are often different (see box). Sixty four per cent of women who died suddenly because of coronary heart disease had no previous symptoms. 

The symptoms may occur with or without chest pain and may come and go.

Risk factors

Older age: When woman reaches the age of 50-52 (the age of natural menopause), the risk of heart disease increases dramatically

Family history: If your parents have CVDs, you have an increased risk of developing it

Race: Risk of CVDs varies with race. For example, Afro-Americans have more severe high blood pressure than Caucasians and are at higher risk of CVDs. This is partly due to higher rates of obesity and diabetes in these populations.

Remember, CVD is largely preventable. You can ensure your heart stays healthy by following a healthy lifestyle. Your heart is in your hands.

Symptoms in women

A feeling of being squeezed or discomfort/pain in the chest, between the breasts or behind the breastbone

Discomfort and/or radiating pain over arms, back, neck, jaw or stomach

Shortness of breath, weakness or fatigue 

Unusual anxiety or nervousness

Indigestion or gas-like pain, nausea

Sudden sweating, dizziness and collapse

What you can do

Be physically active, walk or work out regularly 

Avoid foods full of salt, saturated and trans fats and sugar. Eat lots of fruit and vegetables

Maintain a healthy weight

Quit smoking and avoid respiratory irritants

Limit or stop alcohol use

Stop smoking, avoid products containing tobacco

Those with lung problems should get annual influenza vaccination

World Heart Day: Keep your heart healthy, advise doctors

World Heart Day: Keep your heart healthy, advise doctors

 Indians fall prey to heart diseases more than the people living in western countries. Every year, 17 to 20 lakh people die of heart attack in India reason being lack of physical activity and consuming food having high fat content among people.

As the world observed World Heart Day, city doctors cautioned people and advised to better wake up then never.

Dr Siddhant Jain and Dr Mohammad Ali informed people that every year 1.75 crore people risks various types of cardio-vascular diseases, which is more than the total number of deaths due to malaria, HIV-AIDS and tuberculosis collaboratively.

It is not only men who develop heart disease but out of three women one dies of heart diseases. Even young population too is at risk due to their changing lifestyle.

Doctors suggested few changes which could possibly avert the risk of developing heart disease. They urged people to indulge few minutes daily in physical exercises and get routine health check up done so as to diagnose the rising problem at initial stages.

Vitamin D deficiency ups heart disease risk

Vitamin D deficiency ups heart disease risk
The study involved more than 10,000 Danes and was conducted by the University of Copenhagen and Copenhagen University Hospital.

Vitamin D deficiency has traditionally been linked with poor bone health. However, the results from several population studies indicate that a low level of this important vitamin may also be linked to a higher risk of ischemic heart disease, a designation that covers heart attack, coronary arteriosclerosis and angina. Other studies show that vitamin D deficiency may increase blood pressure, and it is well known that high blood pressure increases the risk of heart attack.
 

Now examined the association between a low level of vitamin D and ischemic heart disease and death in the largest study to date. That low levels of vitamin D compared to optimal levels are linked to 40 percent higher risk of ischemic heart disease, 64 per cent higher risk of heart attack, 57 percent higher risk of early death, and to no less than 81 percent higher risk of death from heart disease.

The higher risks are visible, even after adjustment for several factors that can influence the level of vitamin D and the risk of disease and death. This is one of the methods scientists use to avoid bias.

The population study that forms the basis for this scientific investigation is the Copenhagen City Heart Study, where levels of vitamin D were measured in blood samples from 1981-1983. Participants were then followed in the nationwide Danish registries up to the present.

With this type of population study, we are unable to say anything definitive about a possible causal relationship. But we can ascertain that there is a strong statistical correlation between a low level of vitamin D and high risk of heart disease and early death.

The explanation may be that a low level of vitamin D directly leads to heart disease and death. However, it is also possible that vitamin deficiency is a marker for poor health generally.

The scientists are now working to determine whether the connection between a low level of vitamin D and the risk of heart disease is a genuine causal relationship.
