PURPOSE: We performed 2D speckle tracking transthoracic-echocardiography (TTE) to compare the ability to predict occurrence of major adverse cardiac events (MACE) between global longitudinal strain (GLS) and circumferential strain (GCS) in left ventricular (LV) myocardium in hypertrophic cardiomyopathy (HCM) patients without obstructed coronary arteries. METHODS: We measured 2D LV GLS and GCS retrospectively by TTE within 13months of performance of cardiac CT in 41 consecutive symptomatic HCM patients (27 males; 60±13years) without obstructed coronary arteries on CT...

Ingesting multiple carbohydrate (CHO) types during exercise can improve endurance performance compared to single CHO only. Adding protein to a multiple CHO beverage has been shown to increase cycling time to exhaustion (TTE) compared to a single CHO beverage. However, it is unclear if improvements were due to multiple CHOs or protein, and TTE protocols are not representative of typical race events. This study investigated whether adding protein to a multiple CHO beverage improved performance and recovery in 2 same-day cycling time trials compared to isocaloric multiple CHO-only...

INTRODUCTION: Coronary artery anomalies are the second most common congenital cause of sudden cardiac death (SCD) in young athletes. Some centers have advocated for limited transthoracic echocardiogram (TTE) protocols in the screening of college athletes, which may miss important causes of SCD. PURPOSE: The purpose of this study is to evaluate the ability of screening TTE to determine origin and proximal course of the coronary arteries in intercollegiate athletes...

BACKGROUND: Perioperative evaluation of right ventricular (RV) systolic function is important to follow intraoperative changes, but it is often not possible to assess with transthoracic echocardiographic (TTE) imaging, because of surgical field constraints. Echocardiographic RV quantification is most commonly performed using tricuspid annular plane systolic excursion (TAPSE), but it is not clear whether this method works with transesophageal echocardiographic (TEE) imaging. This study was performed to evaluate the relationship between TTE and TEE TAPSE distances measured with M-mode imaging and in comparison with speckle-tracking TTE and TEE measurements...

BACKGROUND: Anticoagulation remains a controversial issue among hyperthyroid patients with atrial fibrillation (AF). We aimed to evaluate the prevalence of the thrombogenic milieu (TM), detected using transesophageal echocardiography (TEE), among patients with AF related to hyperthyroidism, and to correlate these findings with the clinical embolic risk classification (CHA2DS2-VASc). METHODS: CHA2DS2-VASc score, thyroid hormonal status, time since hyperthyroidism diagnosis, transthoracic echocardiography (TTE) and TEE were assessed in 47 consecutive patients aged between 18 and 65years with AF related to hyperthyroidism...

BACKGROUND: Left ventricular assist devices (LVADs) require serial assessment of right and left ventricular (RV & LV) volumes and function. Because the RV is not assisted, its function is a critical determinant of the hemodynamic and contributes significantly to postoperative morbidity and mortality. We evaluated the feasibility and the accuracy of tomographic-equilibrium radionuclide ventriculography (t-ERV) for the assessment of patients with LVADs. METHODS: Twenty-four patients with LVAD underwent t-ERV...

Objective Left ventricular outflow tract (LVOT) obstruction is a complication in 15-25% of patients with Takotsubo cardiomyopathy and sometimes leads to catastrophic outcomes, such as cardiogenic shock or cardiac rupture. However, the underlying mechanisms have not been clarified. Methods and Results We experienced 22 cases of Takotsubo cardiomyopathy during 3 years, and 4 of these 22 cases were complicated with LVOT obstruction in the acute phase (mean age 79±5 years, 1 man, 21 women). The LVOT pressure gradient in the acute phase was 100±17 mmHg...

BACKGROUND: The concept of shared-decision-making is a well-established approach to increase the participation of patients in medical decisions. Using lifetime risk or time-to-event (TTE) formats has been increasingly suggested as they might have advantages, e.g. in younger patients, to better show consequences of unhealthy behaviour. In this study, the most-popular ten-year risk illustration in the decision-aid-software arriba(TM) (emoticons), is compared within a randomised trial to a new-developed TTE illustration, which is based on a Markov model...

OBJECTIVES: The study sought to investigate the impact of different computing methods for composite endpoints other than time-to-event (TTE) statistics in a large, multicenter registry of unprotected left main coronary artery (ULMCA) disease. BACKGROUND: TTE statistics for composite outcome measures used in ULMCA studies consider only the first event, and all the contributory outcomes are handled as if of equal importance. METHODS: The TTE, Andersen-Gill, win ratio (WR), competing risk, and weighted composite endpoint (WCE) computing methods were applied to ULMCA patients revascularized by percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) at 14 international centers...

Acute poisonings represent a common cause of morbidity and mortality worldwide. The prognostic utility of the transthoracic echocardiography (TTE) parameters combined with brain natriuretic peptide (BNP) in acute poisoning with different xenobiotics, upon admission in the hospital was not evaluated. This prospective observational cohort study included 229 acutely poisoned non-diabetic adults, with a median age of 44 years (range 18-90 years), 50.7% women, with an in-hospital mortality rate of 8.7%. Univariate logistic regression analysis showed that age, the left ventricle kinetic abnormalities, the E wave deceleration time (EDT) and BNP correlated significantly with mortality in acutely poisoned patients...

Improvements in the management of patients undergoing Liver Transplantation (LT) have resulted in a significant increase in survival over recent years. Cardiac disease is now the leading cause of early mortality and the stress of major surgery, haemodynamic shifts, the possibility of haemorrhage or reperfusion syndrome require the recipient to have good baseline cardiac function. The prevalence of coronary artery disease (CAD) is increasing in liver transplant candidates, especially in those with Non-Alcohol related Fatty Liver Disease (NAFLD)...

Pretest guidelines typically stipulate that no exercise should be performed 48 h prior to a maximal incremental exercise [Formula: see text] test. However, no study has specifically investigated if this timescale alters key outcome variables associated with [Formula: see text]. Twenty apparently healthy males split into two equal groups performed [Formula: see text] during three visits (visits 1 - [Formula: see text]EXP1, 2 - [Formula: see text]EXP2 and 4 - [Formula: see text]EXP3). The experimental group only, performed muscle-damaging exercise during visit 3...
