Prevalence of Echocardiographically Detected Ventricular Asynchrony in Patients with Left Ventricular Systolic Dysfunction

Abstract: Objectives QRS complex width is not an accurate marker of cardiac asynchrony. Our aims were to determine the prevalence of cardiac asynchrony by Doppler echocardiography for patients with left ventricular (LV) dysfunction and to evaluate whether QRS width is a reliable method for detecting asynchrony. Methods In all, 316 consecutive patients with a LV ejection fraction less than 40% from 13 hospitals comprised the study group. Interventricular asynchrony was defined by the interventricular mechanical delay. Intraventricular asynchrony was evaluated using the calculation of the septal-to-posterior wall motion delay, the difference between time from Q wave to LV ejection end, and time from Q wave to the end of the systolic wave of the most delayed basal segment by Doppler tissue imaging, the SD of the time from the Q wave to the end of the systolic wave of 4 basal segments, and the maximum difference in the time from the Q wave to the end of the systolic wave of all 4 basal segments. Results Mean age was 62.14 ± 13.5 years (234 men; 74.1%). Interventricular asynchrony was present in 50 (26.2%) patients in the narrow QRS group and in 57 (55.3%) patients in the prolonged QRS group ( P Conclusions Cardiac asynchrony is highly prevalent for patients with LV dysfunction but there is a very poor agreement among the different methods used to detect it. Interventricular asynchrony is more prevalent for patients with prolonged QRS but intraventricular asynchrony is irrespective of the QRS duration. Further studies are needed to evaluate which method is the best to detect cardiac resynchronization therapy responders.

Echocardiographic reference ranges for normal left ventricular layer-specific strain: results from the EACVI NORRE study.

Abstract: Aims - To obtain the normal range for 2D echocardiographic (2DE) measurements of left ventricular (LV) layer-specific strain from a large group of healthy volunteers of both genders over a wide range of ages. Methods and results - A total of 287 (109 men, mean age: 46 ± 14 years) healthy subjects were enrolled at 22 collaborating institutions of the EACVI Normal Reference Ranges for Echocardiography (NORRE) study. Layer-specific strain was analysed from the apical two-, three-, and four-chamber views using 2DE software. The lowest values of layer-specific strain calculated as ±1.96 standard deviations from the mean were -15.0% in men and -15.6% in women for epicardial strain, -16.8% and -17.7% for mid-myocardial strain, and -18.7% and -19.9% for endocardial strain, respectively. Basal-epicardial and mid-myocardial strain decreased with age in women (epicardial; P = 0.008, mid-myocardial; P = 0.003) and correlated with age (epicardial; r = -0.20, P = 0.007, mid-myocardial; r = -0.21, P = 0.006, endocardial; r = -0.23, P = 0.002), whereas apical-epicardial, mid-myocardial strain increased with the age in women (epicardial; P = 0.006, mid-myocardial; P = 0.03) and correlated with age (epicardial; r = 0.16, P = 0.04). End/Epi ratio at the apex was higher than at the middle and basal levels of LV in men (apex; 1.6 ± 0.2, middle; 1.2 ± 0.1, base 1.1 ± 0.1) and women (apex; 1.6 ± 0.1, middle; 1.1 ± 0.1, base 1.2 ± 0.1). Conclusion - The NORRE study provides useful 2DE reference ranges for novel indices of layer-specific strain.

Proactive multiple cardiovascular risk factor management compared with usual care in patients with hypertension and additional risk factors: the CRUCIAL trial

Abstract: Objective:To investigate whether a proactive multifactorial risk factor intervention strategy using single-pill amlodipine/atorvastatin (5/10, 10/10 mg) in addition to other antihypertensive and lipid-lowering therapy, as required, resulted in greater reduction in calculated Framingham 10-year coronary heart disease (CHD) risk compared with usual care (UC) after 52-weeks treatment.Research design and methods:Prospective, multinational, open-label, cluster randomized trial, with the investigator as the unit of randomization. Eligible hypertensive patients were 35–79 years of age, with ≥3 additional cardiovascular risk factors, but no history of CHD and baseline total cholesterol (TC) ≤6.5 mmol/l.Clinical trial registration:www.ClinicalTrials.gov; trial identifier NCT00407537.Main outcome measure:The primary endpoint was calculated Framingham 10-year CHD risk at 52 weeks.Results:Of the 140 randomized sites, 136 sites contributed 1461 patients.

The Freedom SOLO valve for aortic valve replacement: clinical and hemodynamic results from a prospective multicenter trial.

Abstract: BACKGROUND AND AIM OF THE STUDY The study aim was to investigate the early results, hemodynamics and left ventricular remodeling after aortic valve replacement (AVR) with the Freedom SOLO valve, a bovine pericardial valve bioprosthesis, using a single running suture line in a supra-annular position. METHODS Between July 2004 and September 2006, a total of 256 patients (116 males; 140 females; mean age 74.5 +/- 6.4 years; range: 41-89 years) who underwent AVR with the Freedom SOLO valve in nine European institutions were enrolled in the study. The indications for AVR were stenosis in 182 patients, regurgitation in 15, and combined in 57. Preoperatively, 37%, 59% and 4% of the patients were in NYHA classes I-II, III, and IV, respectively. Concomitant procedures were performed in 91 patients (36%). A patient subgroup underwent echocardiography preoperatively (n=192), and at one (n=194) and 12 (n=165) months postoperatively. RESULTS The early mortality was 2.3% (n=6). There were 18 late deaths (6.2%/pt-yr). After 12 months, 82% of the patients were in NYHA class I-II. Linearized rates were 0.69%/pt-yr for bleeding, 0.34%/pt-yr for thromboembolism, 0.0%/pt-yr for structural degeneration and thrombosis, 1.37%/pt-yr for paravalvular leak, and 2.06%/pt-yr for endocarditis. Five patients required reoperation. Twelve-month transprosthetic regurgitation was graded as absent in 92% of cases. The mean gradient was 42.3 +/- 20.2 mmHg preoperatively, 6.5 +/- 3.8 mmHg at one month, and 6.7 +/- 4.1 mmHg at 12 months. The effective orifice area was improved from 0.78 +/- 0.35 cm2 preoperatively to 1.90 +/- 0.56 cm2 at one month and 1.89 +/- 0.56 cm2 at 12 months. The left ventricular mass was decreased by 23%, from 217.8 +/- 77.2 g/m2 preoperatively to 167.4 +/- 68.2 g/m2 at one year. The mean left ventricular ejection fraction was 65.5 +/- 14.2% preoperatively, and 64.5 +/- 12.5% and 66.0 +/- 10.6% at one month and at 12 months, respectively. CONCLUSION The data obtained suggest that the Freedom SOLO stentless bioprosthesis shows excellent early clinical and hemodynamic results, resulting in a significant regression of left ventricular hypertrophy and improvement in left ventricular systolic function.

Global strategy for the diagnosis, management, and prevention of chronic obstructive pulmonary disease: GOLD executive summary.

Abstract: Chronic obstructive pulmonary disease (COPD) remains a major public health problem. It is the fourth leading cause of chronic morbidity and mortality in the United States, and is projected to rank fifth in 2020 in burden of disease worldwide, according to a study published by the World Bank/World Health Organization. Yet, COPD remains relatively unknown or ignored by the public as well as public health and government officials. In 1998, in an effort to bring more attention to COPD, its management, and its prevention, a committed group of scientists encouraged the U.S. National Heart, Lung, and Blood Institute and the World Health Organization to form the Global Initiative for Chronic Obstructive Lung Disease (GOLD). Among the important objectives of GOLD are to increase awareness of COPD and to help the millions of people who suffer from this disease and die prematurely of it or its complications. The first step in the GOLD program was to prepare a consensus report, Global Strategy for the Diagnosis, Management, and Prevention of COPD, published in 2001. The present, newly revised document follows the same format as the original consensus report, but has been updated to reflect the many publications on COPD that have appeared. GOLD national leaders, a network of international experts, have initiated investigations of the causes and prevalence of COPD in their countries, and developed innovative approaches for the dissemination and implementation of COPD management guidelines. We appreciate the enormous amount of work the GOLD national leaders have done on behalf of their patients with COPD. Despite the achievements in the 5 years since the GOLD report was originally published, considerable additional work is ahead of us if we are to control this major public health problem. The GOLD initiative will continue to bring COPD to the attention of governments, public health officials, health care workers, and the general public, but a concerted effort by all involved in health care will be necessary.

Harmonizing the Metabolic Syndrome A Joint Interim Statement of the International Diabetes Federation Task Force on Epidemiology and Prevention; National Heart, Lung, and Blood Institute; American Heart Association; World Heart Federation; International Atherosclerosis Society; and International Association for the Study of Obesity

Abstract: A cluster of risk factors for cardiovascular disease and type 2 diabetes mellitus, which occur together more often than by chance alone, have become known as the metabolic syndrome. The risk factors include raised blood pressure, dyslipidemia (raised triglycerides and lowered high-density lipoprotein cholesterol), raised fasting glucose, and central obesity. Various diagnostic criteria have been proposed by different organizations over the past decade. Most recently, these have come from the International Diabetes Federation and the American Heart Association/National Heart, Lung, and Blood Institute. The main difference concerns the measure for central obesity, with this being an obligatory component in the International Diabetes Federation definition, lower than in the American Heart Association/National Heart, Lung, and Blood Institute criteria, and ethnic specific. The present article represents the outcome of a meeting between several major organizations in an attempt to unify criteria. It was agreed that there should not be an obligatory component, but that waist measurement would continue to be a useful preliminary screening tool. Three abnormal findings out of 5 would qualify a person for the metabolic syndrome. A single set of cut points would be used for all components except waist circumference, for which further work is required. In the interim, national or regional cut points for waist circumference can be used.

Recommendations for cardiac chamber quantification by echocardiography in adults: an update from the American Society of Echocardiography and the European Association of Cardiovascular Imaging.

Abstract: The rapid technological developments of the past decade and the changes in echocardiographic practice brought about by these developments have resulted in the need for updated recommendations to the previously published guidelines for cardiac chamber quantification, which was the goal of the joint writing group assembled by the American Society of Echocardiography and the European Association of Cardiovascular Imaging. This document provides updated normal values for all four cardiac chambers, including three-dimensional echocardiography and myocardial deformation, when possible, on the basis of considerably larger numbers of normal subjects, compiled from multiple databases. In addition, this document attempts to eliminate several minor discrepancies that existed between previously published guidelines.
