Latest updates on the coronavirus and heart disease
Smoking is estimated to cause nearly 10 per cent of cardiovascular disease (CVD) and is the second leading cause of CVD, after high blood pressure.1 The impact of tobacco smoke is not confined solely to smokers. Nearly 6 million people die from tobacco use or exposure to secondhand smoke, accounting for 6 per cent of female and 12 per cent of male deaths worldwide, every year. By 2030 tobacco-related deaths are projected to increase to more than 8 million deaths a year.1 Smoking is, however, avoidable and advancing a tobacco-free world is a key strategic priority for the World Heart Federation.
Tobacco acts in a number of ways to cause CVD. Its use, whether by smoking or chewing, damages blood vessels, temporarily raises blood pressure and lowers exercise tolerance. Moreover, tobacco decreases the amount of oxygen that the blood can carry and increases the tendency for blood to clot. Blood clots can form in arteries causing a range of heart diseases that ultimately result in a stroke or sudden death.
