A 59 year old male is admitted complaining of chest pain and dyspnea. ST elevation and T wave inversion were seen on the EKG in V2,V3 and V4. IV thrombolytic therapy was started in ED. Indications of successful reperfusion would include all of the following except: (A) pain cessation (B) decrease in CK or troponin (C) reversal of ST segment elevation with return to baseline (D) short runs of ventricular tachycardia - ANSWER- (B)Coronary artery reperfusion due to PCI or fibrinolysis results in an ELEVATION of creatinine kinase (CK) or troponin, not decrease. The theory is that the return of blood flow distal to the occlusion can result in 'reperfusion injury' of the muscle, elevating cardiac biomarkers. The other 3 choices are indicators of reperfusion: Pain cessation, reversal of ST segment elevation with return to baseline, short runs of ventricular tachycardia. Which of the following are predominant signs of left ventricular systolic dysfunction? (A) pedal edema, ascites, hepatomegaly, weight gain, ejection fraction less than 40% (B) S4, bibasilar crackles, hypertension, ejection fraction greater than 40% S3, frequent new cough, bibasilar crackles, ejection fraction less than 40% D hypertension, murmur, chest pain, weight gain, ejection fraction greater than 40% - ANSW
