Obese patients are always at risk of getting ischemic heart disease because of fatty plaques narrowing their coronary vessels. Physicians will now be able to predict the incidence of ischemic heart diseases among obese patients through a newer technique in the form of stress Cardiac magnetic resonance (CMR) imaging, which is quite different from the alternative imaging techniques in the form of PET and SPECT which are more expensive and expose the patient to a greater dose of radiations as compare to Stress CMR imaging. Stress CMR has the added advantage that it has more temporal and spatial resolution as compared to the older imaging procedures.
A cohort study was conducted over 285 individuals having a BMI greater than 30 and who were suffering from suspected MI. The basic goal of this study was to see whether stress CMR gives a true prediction about the incidence of myocardial infarction among obese patients or not. The major predictor for any adverse cardiovascular event was CMR induced ischemia which was seen among these patients. The patients were then followed for a median 2.1 years after which it was concluded that patients who had no induced ischemia with stress CMR showed no incidence of any cardiac illness in the next 10 years. However, those patients who suffered stress CMR induced ischemia, or who were already suffering from some kind of heart illness, such patients showed rapid progression in their cardiac issues and even some of them suffered deaths as well.
Since obesity has been on rising since last few decades, imaging techniques in the form of stress CMR would really benefit the mankind by predicting the ischemic event long before it would really occur in the individual thus alarming him about his health.
