Cardiovascular disease is the No. 1 cause of death in the United States, so it makes sense to follow a heart-healthy lifestyle. If you have been diagnosed with cardiovascular disease or have risk factors such as a family history of heart problems or high blood pressure, you probably have a lot of questions and concerns. A free seminar may give you some answers.

"Keeping Your Heart Healthy and Strong," sponsored by ProHealth physicians group, offers tips about medications and advice about diet and exercise from cardiologist Dr. Marie Roethel. After the seminar, there will be time for questions and answers.

The seminar is Thursday at 6 p.m. at ProHealth's Lake Success headquarters. Registration is required. Call 516-608-6840.
