Many people ignore the warnings posted before gym sessions that advise them to see a doctor before engaging in strenuous Exercise. Isn`t it true that exercise is healthy for you? Certain diseases, however, may make the higher heart rate associated with exercise harmful.

Researchers from the Indian Institute of Technology Kharagpur found that an elevated heart rate can induce a stroke in patients with highly blocked carotid arteries. Contrastingly, for healthy patients and those with only slightly blocked arteries, exercise is beneficial for maintaining healthy blood flow.
