RAE, RVH, RBBB, marked clockwise rotation of heart, a QS pattern in leads III and aVF, LAD, PACs, and SVTs were significantly more prevalent in patients with severe COPD than in patients with mild or moderate COPD.

An elevated triglyceride (TG)/high-density lipoprotein (HDL) ratio has been described as a predictor of insulin resistance and cardiovascular events. We evaluated whether a TG/HDL ratio > or = 3.5 was associated with the burden of coronary artery disease (CAD) on cardiac catheterization. A retrospective chart review of 156 consecutive adults presenting to the Montefiore Medical Center Emergency Department with symptoms of unstable angina and no known history of CAD who underwent cardiac catheterization as part of their index hospitalization was performed. TG and HDL data were available in 100 patients within 6 months prior to admission and no more than 24 hours after presentation. A priori, a burden of CAD score was developed. On multivariate analysis, a TG/HDL ratio > or = 3.5 was associated with the burden of CAD (odds ratio, 2.87; 95% confidence interval, 1.03-7.96; p = 0.04). Further study is warranted.

SummaryBackgroundSome patients with right heart failure develop cardiac hepatopathy (CH). The pathophysiology of CH is thought to be secondary to hepatic venous congestion and arterial ischemia. We sought to define the clinical and hemodynamic characteristics associated with CH.Material/MethodsA retrospective cross sectional analysis was performed in which subjects were identified from our institutional cardiology database if echocardiography showed either right ventricular (RV) hypokinesis or dilatation, and was performed within 30 days of right heart catheterization. A chart review was then performed to identify patient clinical characteristics and to determine if the patients had underlying liver disease. Subjects with non-cardiac causes for hepatopathy were excluded.ResultsIn 188 included subjects, etiology for right heart dysfunction included left heart failure (LHF), shunt, pulmonary hypertension, mitral- tricuspid- and pulmonic valvular disease. On multivariate analysis, higher RV diastolic pressure and etiology for RV dysfunction other than LHF were both associated with CH. Low cardiac output was associated with CH only amongst those without LHF.ConclusionsCH is most often seen in subjects with elevated RV diastolic pressure suggesting a congestive cause in most cases. CH associated with low cardiac output in patients without LHF suggests that low flow may be contributing to the patophysiology in some cases.
