A recent study has made a shocking discovery that people suffering from poverty and social deprivation are more likely to develop a serious heart disease called endocarditis. This disease occurs when an infection spreads to the inner part of the heart, especially the valves. If not diagnosed and treated promptly, it can be fatal for the heart. According to experts, this infection usually occurs when bacteria or germs enter the blood and reach the heart. Often, these germs enter the body through teeth, skin or a wound and then form clusters on the heart valves, which affects blood flow.
