Since my coronary artery disease, which resulted in a heart attack, has been successfully treated with stents and medication, the support I need is primarily from my own efforts to remain healthy. That means some don'ts (alcohol, nicotine, excessive consumption of red meat, carbohydrates, salt) and some dos (exercise, balanced diet, hydration, semi-annual visits to my cardiologist). Since I'm retired, I also try to maintain a balanced schedule with lots of varied activities. I find that sitting around leads to bad habits, especially dietary.
