A previously healthy 30-year-old African American male presented to our hospital with diabetic ketoacidosis as his first manifestation of diabetes. A transthoracic echocardiogram (TTE) was performed with contrast, which showed isolated noncompaction of the left ventricular myocardium (INVM). The case presented here is followed by an extensive review of the available literature.

The PLAATO device decreases the risk of stroke in a high-risk cohort of AF patients. Furthermore, the safety of this device is confirmed during this long-term follow-up study. A larger trial is needed to validate these findings.

Background: The prognostic value of peak cardiac troponin (cTn) in different types of acute myocardial infarction (AMI) under the universal clinical classification is unknown. Hypothesis: We tested the hypothesis that the prognostic value of cTn varies with its peak level and type of AMI. Methods: We studied 345 consecutive patients with AMI with mean follow-up of 30.6 months according to quartiles of peak cTn level (QPTL) and the type of AMI. The study outcomes were the major adverse cardiovascular events (MACE; composite of all causes of mortality and recurrent AMI) and the individual components of MACE. Results: The study included patients with AMI Type 1 (n = 276), type 2 (n = 54), ST-segment elevation myocardial infarction (STEMI; n = 159), and non-ST-segment elevation myocardial infarction (NSTEMI; n = 186). Overall, peak cTn level was an independent predictor of MACE (hazard ratio [HR]: 1.001, 95% confidence interval [CI]: 1.000-1.003, P = 0.01) and death (HR: 1.002, 95% CI: 1.001-1.004, P = 0.003), but not of recurrent AMI. The highest risk of MACE and death was in the highest QPTL (61.6%, P = .016 and 66.3%, P = 0.021, respectively) while the highest risk of recurrent AMI was in the lowest QPTL (83.7%, P = 0.04). Quartiles of peak cTn level were significantly associated with increased risk of MACE and death in patients with Type 1 (all P = 0.01) and STEMI (P = 0.01 and P = 0.02, respectively), but no association existed in type 2 or NSTEMI patients. Conclusions: Overall, peak cTn predicts the risk of MACE and death but not the risk of AMI. While in Type 1 and STEMI patients, QPTL are associated with risk of MACE and death, no association exists in type 2 or NSTEMI patients. IntroductionThe universal clinical classification (UCC) of acute myocardial infarction (AMI) recommends cardiac troponin as the preferred biomarker of cardiomyocyte necrosis.
