The American College of Physicians (ACP) guideline recommends that all patients first be evaluated with the modified cardiac risk index by Detsky.13 [Evidence level C, expert opinion] Patients stratified as Class I are considered low risk but should be further stratified with low-risk variables identified in separate studies.14,15 [Reference 14Evidence level B, retrospective study] Patients stratified as Class II or Class III on the modified cardiac risk index are at high risk for perioperative cardiac events (Figure 2).8,1315. A reinfarction rate of 27 to 37 percent occurred in patients who underwent surgery within three months of infarction. This cluster of abnormalities include abdominal obesity (seen either by a large waist circumference or a high body mass index [BMI]), high blood pressure, high triglycerides, low HDL cholesterol (the good cholesterol) and high fasting blood sugar. METs_max = (4.38 * T - 3.9) / 3.5 For men: METs_max = (14.8 - (1.379 * T) + (0.451 * T) - (0.012 * T)) / 3.5 where T is the time the subject spent on the treadmill running. eating, dressing, bathing, using the toilet No (0) Yes (+2.75) 2 Walk indoors No (0) Yes (+1.75) 3 Walk 1-2 blocks on level ground No (0) Yes (+2.75) 4 Climb a flight of stairs or walk up a hill No (0) Yes (+5.5) 5 Run a short distance No (0) Yes (+8) METs, or the rate at which someone burns calories, are calculated by calculating an individuals calorie burn rate. The reinfarction rate remained stable (5 percent) for patients who underwent surgery more than six months after MI.
