ML Kothari et al have highlighted some important facts about heart disease and its treatment. Despite the constant advances in medical science, there are many lacunae in our knowledge of this condition. High technology methods of diagnosis and treatment have not solved questions related to the causes of heart disease. They have also failed to alter the course of disease in many heart patients. Physicians who forget this and advise patients to undergo tests and procedures which will not be beneficial to them are indeed unethical, and the authors should be complimented for reminding cardiologists of the inadequacies in their field.
