Heart Disease and Stroke
Why Heart Disease and Stroke Matter
Globally, more people die from cardiovascular diseases (CVDs) each year than from any other cause. In 2008, about 17.3 million people died from CVDs, or about 30% of all global deaths. About 7.3 million of these deaths were due to coronary heart disease and 6.2 million to stroke. CVDs are projected to remain the single leading worldwide cause of death, reaching 23.3 million deaths annually by 2030. Risk factors that can be modified through lifestyle changes include unhealthy diet, tobacco use, physical inactivity, and harmful alcohol use. An aging population and rising rates of obesity, diabetes, hyperlipidemia, and hypertension all contribute to escalating CVD deaths.
UNC is working with nine other universities across the United States on a massive two-decade study to better understand CVD and its risk factors within four communities in Maryland, Minnesota, Mississippi and North Carolina. U.S. deaths from CVD have dropped by more than half in the past 30 years, largely due to declines in smoking and improvements in treating high blood pressure and cholesterol levels. But it is uncertain whether these gains will continue, and more research on causes and prevention is critical. This study and others are yielding enormous insights on the impact of race, socioeconomic differences, genetic factors and health problems such as gum disease on CVD risk.
