Three years back, smoking was banned in one city of Colorado and now after three years a considerable decrease in heart attacks hospitalizations has been found there, which indicates how injurious smoking is to health. This Govt. study was the longest running of its kind and it showed that there was 41% decrease in heart attack hospitalization cases within three years after workplace smoking ban in Pueblo, Colo city. The researchers didn’t notice any such drop in two adjacent areas which indicates that it was mainly due to smoking ban.

“The study indicates that one terrible and less-recognized cause of heart problems related deaths is secondhand smoke,” says Terry Pechacek, the lead author of the study.

US researchers say that their tests on mice may help to develop a new drug to cut permanent heart scars that occur due to heart attacks.

In their study, the researchers blocked a particular protein in mice that proved quite sufficient to cut their possible heart damage caused by a heart attack.

The Study, published in the latest issue of the journal Nature Cell Biology, can also prove helpful to employ other treatments like stem cells for a better heart function.

When there isn’t sufficient amount of oxygen in the heart during a cardiac arrest, it becomes the cause of a series of damaging events in the heart.

This injury becomes the cause of inflammation in the heart that may permanently disturb its capability to pump blood in a proper way.

According to a new study, lack of a vitamin D that is received through sunlight can increase the risk of strokes and heart attacks.

Dr. James H. O’Keefe, who led the study, says in this connection: “There are many studies that show link between vitamin D deficiency and higher risk of cardiovascular diseases.”

“Usually risk of high blood pressure, left ventricle stiffening and diabetes are related to vitamin D deficiency. People deficient in vitamin D have higher ratio of inflammation and inflammation is considered quite important for heart disease.”

According to some experts, almost 30% children and teens, and half of adults in the US suffer from vitamin D deficiency.

Data from the Framingham Heart Study shows that people with below 15nanograms/ml blood have two times more risk of having a heart attack or some other cardiovascular disease.
