Despite hygienic food, regular exercizes one will not know as to whether his heart is developing coronary artery disease or not. No more! You can get the status of your coronaries to assess whether they are developing plaques (which lead to narrowing and hence ischemic heart disease). Dr Sanjay Gupta in the Time magazine (January 22, 2007) suggests that use of CT Angiography (a kind of CAT scan)- which is non invasive- will tell you of any developing plaque. Thus before you attain the age of 40, get one such scan and then at least you know the exact status of your heart. And the old mantra of being a vegetarian is now fast catching up. Be vegetarian and be more healthy!
