The purpose of this study was to investigate the effects of T-wave amplitude and ECG lead on beat-to-beat QT interval variability (QTV) in patients with myocardial infarction (MI) compared to healthy subjects. Standard resting 12-lead ECGs of 79 MI patients and 69 healthy subjects were investigated. Beat-to-beat QT intervals were measured separately for each lead using a template matching algor...

Objective: To investigate whether dental hygienist students through peer-learning can increase their ability to conduct motivational interviewing (MI) compared with students who follow the regular curriculum. The aim was also to get an insight into the process of learning of MI. Materials and Methods: Ten dental hygienist students were randomly selected to either the intervention group (IG) or ...

The aim of this study was to investigate the effect motor imagery (MI) combined with instructional self-talk on service performance in young novice tennis players. participants were assigned one three groups: control, MI, or MI + self-talk. They performed a pretest (10 serves), participated 5 days intervention sessions, and finally posttest similar pretest. During 20 serves. control group not g...

Ligation of the left anterior descending coronary artery (LAD) is used to induce experimental myocardial infarction (MI). Most previous studies have focused on the early postoperative period, while data on mid-term follow-up are scanty. This study examined the mid-term effects of LAD ligation in 95 MI rats and 28 controls. The following parameters were evaluated: systemic blood pressure (SBP), ...

Our aim was to establish parameters describing systolic and diastolic function in mice after myocardial infarction (MI) that distinguish MI with pulmonary congestion from MI without congestion. Echocardiography, left ventricular (LV) catheterization, and infarct size measurements were performed on days 3, 5, 7, and 14 after ligation of the left coronary artery in C57BL/6 mice. Sham-operated mic...

AIMS To assess the intricate relationship between myocardial infarction (MI) location and size and their reciprocal influences on post-infarction left ventricular (LV) remodelling. METHODS AND RESULTS A cohort of 260 reperfused ST-segment elevation MI patients was prospectively studied with cardiovascular magnetic resonance at 1 week (baseline) and 4 months (follow-up). Area at risk (AAR) and...

AIMS Our aim was to test the hypothesis that angiotensin II receptor blockade combined with exercise training after myocardial infarction (MI) could attenuate post-MI left ventricular remodelling and preserve cardiac function. METHODS AND RESULTS Sprague-Dawley rats underwent ligation of the left descending coronary artery, resulting in MI, or a sham operation. Losartan treatment and exercise...

AIM Left ventricle (LV) regional fractional area change (RFAC) measured by cardiac magnetic resonance (CMR) allows the non-invasive localization and quantification of the degree of myocardial infarction (MI), and could be applied to assess the effectiveness of pharmacological or regenerative therapies. Here we investigate the ability of RFAC to identify regional dysfunction and discriminate the...
