The leading cause of death in America is heart disease, which encompasses any ailment that affects the heart or blood vessels. Even though some cardiac conditions run in families, many can be avoided with medication, dietary modifications, and consistent exercise. Since preventive interventions have successfully lowered the risk of heart disease, the focus should now be on improving cardiovascular wellbeing. Even while heart disease may run in families, risk factors may often be easily addressed with diet, exercise, and quitting smoking. Furthermore, individuals can reduce the symptoms of ailments like arrhythmias, which are disorders in which smoking, prior heart attacks, congenital heart problems, or stress disrupt the electrical system that controls heartbeat. Medication, surgery, or the implantation of a cardioverter-defibrillator device are the available treatments for arrhythmias.
