Investigation of elastic features of aorta and color M-mode flow propagation velocity (APV) of descending aorta in the patients with ischemic and non-ischemic dilated cardiomyopathy.
Aortic flow propagation velocity (APV) is a novel echocardiographic parameter used in coronary artery disease. It has also been used for the evaluation of aortic stiffness. In the present study, APV was measured in patients with ischemic and non-ischemic dilated cardiomyopathy (DCM) and was compared with the parameters of aortic stiffness such as aortic distensibility (AD) and aortic strain (AS). ⋯ APV was found to be significantly correlated with AS (r = 0.645, p < 0.001) and AD (r = 0.604, p < 0.001). In ROC analysis, the area under the curve (AUC) value for APV was 0.999 (p = 0.000) for detection of patients ischemic DCM and non-ischemic DCM. APV may be considered to be a novel and a simple echocardiographic marker, for both, distinguishing ischemic from non-ischemic DCM as well as for the presence of dilated cardiomyopathy with or without critical coronary artery disease.

Comparative Study Observational StudyThe feasibility of tricuspid annular plane systolic excursion performed by transesophageal echocardiography throughout heart surgery and its interchangeability with transthoracic echocardiography.
Tricuspid annular plane systolic excursion (TAPSE) is a robust measure of RV function, but the performance of transesophageal echocardiography (TEE) measured TAPSE during surgery is not well established. We aim to evaluate feasibility of various TEE views before, during and after surgery. Furthermore, we compare performance of individual TEE measurements depending on view and method (AMM- and M-mode as well as 2D) as well as TAPSE measured using TEE with transthoracic echocardiography (TTE) TAPSE. ⋯ TDI demonstrated a high reliability throughout surgery. RV function can be evaluated by TAPSE and TDI using TEE during surgery. TEE values from the transgastric view demonstrated high performance throughout surgery and a good agreement with TTE TAPSE measurements.

Relationship between airflow obstruction and coronary atherosclerosis in asymptomatic individuals: evaluation by coronary CT angiography.
Airflow obstruction is associated with increased cardiovascular morbidity and mortality. However, the causal mechanisms linking airflow obstruction with higher incidence of cardiovascular events remain elusive. We evaluated the relationship between airflow obstruction, a key feature of chronic obstructive pulmonary disease (COPD), and prevalence, extent, and severity of coronary atherosclerosis in a large cohort of asymptomatic subjects. ⋯ Airflow obstruction was associated with higher CACS (p = 0.043), ABS (p = 0.002), ABOS (p = 0.017), SIS (p = 0.003), and SSS (p = 0.002). Multivariable analyses adjusted for conventional cardiovascular risk factors revealed that airflow obstruction was independently associated with presence of CAD (odds ratio 1.673, confidence intervals [CI] 1.002-2.789, p = 0.048). In this asymptomatic population, the presence of airflow obstruction was associated with a greater prevalence, extent, and severity of coronary atherosclerosis and was seen to be an independent predictor of the presence of CAD.

Intramyocardial dissecting hematoma in anterior wall ST elevation myocardial infarction: impact on left ventricular remodeling and prognosis.
Intramyocardial dissecting hematoma is an uncommon complication of myocardial infarction potentially leading to cardiac rupture. The aim of the present study was to investigate coronary reperfusion results, left ventricular (LV) function recovery and remodeling and clinical outcomes in patients with anterior STEMI complicated by intramyocardial hematoma. We prospectively studied 87 patients (mean age 59 ± 10 years; 88% male) with anterior STEMI (42 with intramyocardial hematoma) in order to evaluate coronary reperfusion results, LV remodeling (≥15% increase in end-systolic volume) and clinical outcomes (cardiac death, non-fatal reinfarction, and hospitalization for congestive heart failure) at 24 months. ⋯ Hematoma (log-rank test, χ2 = 9.849; p = 0.002) and LV remodeling (log-rank test, χ2 = 13.770; p < 0.001) were associated to a higher rate of adverse events. Cox analysis identified LV remodeling as the only independent predictor of adverse events (hazard ratio = 3.912; 95% confidence interval, 1.429-10.714; p = 0.008). Intramyocardial dissecting hematoma complicating anterior STEMI is an independent determinant of LV remodeling and is associated to poor prognosis.
