Heart Disease Mortality Slashes Down

For the past decades, mortality rates of heart diseases in US have been a hot issue which alarmed the whole population to take necessary precautions with regards to their health. It was noted today that the figures of deaths from heart diseases are already declining according to the Center for Disease Control (CDC) in US.

Since 1960, there is a steady decline on the number of age-adjusted deaths from coronary heart diseases based on the data analyzed by the Center for Disease Control (CDC). This steady decline is brought about by multiple factors such as the greater control for the risk factors which in return decreased the incidence rates of coronary heart diseases, and improved treatment modalities.

Coronary heart disease (CHD) is a condition in which plaque builds up inside the coronary arteries. These arteries supply oxygen-rich blood to your heart muscle. Plaques are made up of fat, cholesterol, calcium, and other substances found in the blood. When the arteries are filled-up with plaques, it results to blockage of blood supply to the heart muscles, leading to heart muscle damage. Risk factors for this disease include smoking, obesity, and sedentary lifestyle. Awareness of these risk factors, improved the general health condition of the population leading to a decline in coronary heart disease cases.

The Million Hearts national initiative, which can prevent 1 million heart attacks and strokes over the next five years, focuses on actions people can take themselves and actions that businesses, communities and health providers can take to prevent heart attacks and strokes today.” CDC Director Thomas R. Frieden, M.D., M.P.H said.

CDC analyzed data from Behavioral Risk Factor Surveillance System (BRFSS) surveys for the period 2006–2010. BRFSS is a state-based, random-digit–dialed telephone survey of the U.S. civilian, non-institutionalized population aged ?18 years. The group estimated state-specific CHD prevalence by age, sex, race or ethnicity, and education. Findings of the said analysis reported that although there is a general decline of the prevalent cases of CHD of the whole population in US, there are significant differences in the figures by age, sex, race, education and state of residence.

From 2006 to 2010, age-adjusted CHD prevalence in the United States declined overall from 6.7 to 6.0 per cent. There were similar observations across all age group, sex, and education grouping. In addition, declines from 2006 to 2010 were observed among whites revealing 6.4% to 5.8 per cent and Hispanics reaching 6.9 to 6.1 per cent. Also, on the state category, from 2006 to 2010, the greatest statistically significant linear declines in age-adjusted CHD prevalence were 23.1per cent in West Virginia (from 10.4% to 8.0%) and 22.1 per cent in Missouri (from 7.7% to 6.0%).

According to WHO, an estimated 17 million people die of CVDs, particularly heart attacks and strokes, every year. A substantial number of these deaths can be attributed to tobacco smoking, which increases the risk of dying from coronary heart disease and cerebrovascular disease 2–3 fold. Physical inactivity and unhealthy diet are other main risk factors which increase individual risks to cardiovascular diseases.
