In this video, Dr. Viveka Kumar, Senior Director - Cath Lab, Max Super Speciality Hospital, Saket, will discuss the importance of early diagnosis in acute MI. If the treatment is done early, within one hour, the myocardium will be as good as the normal person. This time is known as the golden hour. As the time is delayed the benefits becomes lesser. The acute MI patients should be treated within first 6 hours with thrombolysis and primary PTCA for maximum benefits. Beyond 12 – 24 hours there is no benefit. Primary PTCA can save the life and decrease the mortality.
