BackgroundEpicardial fat is a visceral thoracic fat and known to be related with presence of dyslipidemia and coronary arterial stenosis. We evaluated the effects and differences of statins on epicardial fat thickness (EFT) in patients underwent successful percutaneous coronary intervention (PCI).MethodsIn this retrospective cohort study, we enrolled consecutive patients underwent successful PCI and scheduled six to eight-months follow-up coronary angiography from March 2007 to June 2009. EFT was measured by echocardiography twice at the time of PCI and the follow-up coronary angiography. We included 145 patients (58 females; mean, 63.5 ± 9.5 years).ResultsOf the 145 patients, 82 received 20 mg of atorvastatin (atorvastatin group) and 63 medicated with 10 mg of simvastatin with 10 mg of ezetimibe (simvastatin/ezetimibe group). With statin treatments, total cholesterol concentration (189.1 ± 36.1 to 143.3 ± 36.5 mg/dL, p < 0.001), triglycerides (143.5 ± 65.5 to 124.9 ± 63.1 mg/dL, p = 0.005), low density lipoprotein-cholesterol (117.4 ± 32.5 to 76.8 ± 30.9 mg/dL, p < 0.001) and EFT (4.08 ± 1.37 to 3.76 ± 1.29 mm, p < 0.001) were significantly decreased. Atorvastatin and simvastatin/ezetimibe showed similar improvements in the cholesterol profiles. However, atorvastatin decreased EFT more significantly than simvastatin/ezetimibe (EFT change 0.47 ± 0.65 in the atorvastatin vs. 0.12 ± 0.52 mm in the simvastatin/ezetimibe group; p = 0.001).ConclusionIn this study, the atorvastatin group showed significant reduction in EFT than in the simvastatin/ezetimibe group. This might be originated from the statin difference. More large, randomized study will be needed to evaluate this statin difference.

In this study, S' velocity measured by TDI showed a significant correlation with three dimensional LVEF and can be used to detect patients with LV systolic dysfunction.

The exact pathogenesis of transient mid- and basal ventricular ballooning, a new variant of transient left ventricular (LV) ballooning, remains unknown. We report two cases of transient mid- and basal ventricular ballooning associated with catecholamines. These cases suggest that catecholamine-mediated myocardial dysfunction might be a potential mechanism of this syndrome.

Cor pulmonale (CP) is defined as the structural and functional alternation of the right ventricle (RV) caused by primary disorders of the respiratory system. We aimed to differentiate acute CP complicated with massive pulmonary thromboembolism (PTE) from the chronic form due to severe chronic obstructive pulmonary disease (COPD) with strain analysis of RV in the emergency department. We included patients showing echocardiographic features of pulmonary hypertension in the emergency department. From March 2005 to July 2006, a total of 52 patients, 24 consecutive patients with acute CP (ten males, mean 69 ± 10 years) and 28 consecutive patients with chronic CP associated with severe COPD (22 males, mean 63 ± 14 years), were included. Echocardiographic data and strain analyses were obtained with GE Vivid 7. There was no statistical difference in age, fractional area change of RV, TR Vmax, and Tei index in both groups. However, more males were included in the chronic group. Midventricular systolic strain of RV was significantly increased in patients with acute CP. Regarding the midventricular systolic strain in the detection of acute CP by the receiver operating curve analysis, the best sensitivity and specificity were obtained when -12.2% was applied as the criterion (more than -12.2% for predicting an acute CP, the sensitivity, specificity, and accuracy were 83.3, 78.6, and 80.8%, respectively). Midventricular systolic strain of RV can be used in the differentiation between acute and chronic CPs in the emergency department.
