Value of non-apical echocardiographic views in the up-grading of patients with aortic stenosis.

. Echocardiography assessment from apical five-chamber view (A5CV) is the standard technique for aortic stenosis (AS) grading. Data on non-apical views, such as right parasternal (RPV), subcostal (SCV) and suprasternal notch (SSNV), is scarce and constitutes the aim of our study.

Economic evaluation of complete revascularization versus stress echocardiography-guided revascularization in the STEACS with multivessel disease.

Introduction And Objectives: Economic studies may help decision making in the management of multivessel disease in the setting of myocardial infarction. We sought to perform an economic evaluation of CROSS-AMI (Complete Revascularization or Stress Echocardiography in Patients With Multivessel Disease and ST-Segment Elevation Acute Myocardial Infarction) randomized clinical trial.

Methods: We performed a cost minimization analysis for the strategies (complete angiographic revascularization [ComR] and selective stress echocardiography-guided revascularization [SelR]) compared in the CROSS-AMI clinical trial (N=306), attributable the initial hospitalization and readmissions during the first year of follow-up, using current rates for health services provided by our health system.

Comparison of two strategies in a chest pain unit: stress echocardiography and multidetector computed tomography.

Introduction And Objectives: This study aimed to compare stress echocardiography (SE) and multidetector computed tomography (MCT) in patients admitted to a chest pain unit to detect acute coronary syndrome (ACS).

Methods: A total of 203 patients with ≥ 1 cardiovascular risk factor, no ischemic electrocardiogram changes and negative biomarkers were randomized to SE (n=103) or MTC (n=100). The primary endpoint was a combination of hard events (death and nonfatal myocardial infarction), revascularizations, and readmissions during follow-up.

Angiographically Guided Complete Revascularization Versus Selective Stress Echocardiography-Guided Revascularization in Patients With ST-Segment-Elevation Myocardial Infarction and Multivessel Disease: The CROSS-AMI Randomized Clinical Trial.

Background: Recent trials suggest that complete revascularization in patients with acute ST-segment-elevation myocardial infarction and multivessel disease is associated with better outcomes than infarct-related artery (IRA)-only revascularization. There are different methods to select non-IRA lesions for revascularization procedures. We assessed the clinical outcomes of complete angiographically guided revascularization versus stress echocardiography-guided revascularization in patients with ST-segment-elevation myocardial infarction.

The causes, consequences, and treatment of left or right heart failure.

Chronic heart failure (HF) is a cardiovascular disease of cardinal importance because of several factors: a) an increasing occurrence due to the aging of the population, primary and secondary prevention of cardiovascular events, and modern advances in therapy, b) a bad prognosis: around 65% of patients are dead within 5 years of diagnosis, c) a high economic cost: HF accounts for 1% to 2% of total health care expenditure. This review focuses on the main causes, consequences in terms of morbidity, mortality and costs and treatment of HF.

[Contrast-induced nephropathy and acute renal failure following emergent cardiac catheterization: incidence, risk factors and prognosis].

Introduction And Objectives: The aim was to investigate the incidence and prognosis of, and predictive factors for, acute renal failure following emergent cardiac catheterization.

Methods: The study involved 602 consecutive patients who underwent emergent cardiac catheterization. Acute renal failure (ARF) was defined as an increase in serum creatinine level > or =0.

[Prognostic value of treadmill exercise echocardiography].

Introduction And Objectives: Exercise echocardiography (EE) is useful for diagnosing coronary disease, but little is known about its value for risk stratification. We aimed to determine: a) whether data from EE supplemented clinical data and data from exercise testing and resting echocardiography in predicting cardiac events; and b)whether the number and location of abnormal regions and their responses to exercise influenced risk stratification.

Patients And Method: The 2,436 patients referred for EE were followed up for 2.

[Exercise echocardiography to differentiate dilated cardiomyopathy from ischemic left ventricular dysfunction].

Objectives: Previous studies have shown the usefulness of dobutamine echocardiography to differentiate dilated cardiomyopathy (DC) from ischemic left ventricular dysfunction (ILVD), but no studies have been made using exercise echocardiography (EE). We hypothesized that most patients with DC have some contractile reserve and experience an increase in left ventricular ejection fraction (LVEF) during exercise, as opposed to patients with ILVD. Differences in response to EE may be useful to clinically differentiate between these two entities.
