BACKGROUND Type 2 diabetes mellitus (DM2) may induce epicardial coronary artery diseases and left ventricular myocardial damaging as well. Left ventricular dysfunction was found in DM2. In this research, we compared the left ventricular dysfunction of coronary artery disease (CAD) patients with and without type 2 diabetes mellitus as well as normal controls using the volume-time curve of cardia...

Lodging-resistant rice (Oryza sativa) cultivars usually show slow grain filling when nitrogen is applied in large amounts. This study investigated the possibility that a hormonal change may mediate the effect of water deficit that enhances whole plant senescence and speeds up grain filling. Two rice cultivars showing high lodging resistance and slow grain filling were field grown and applied wi...

BACKGROUND Altered diastolic filling is an important contributor to several cardiovascular disorders. Multiple lines of evidence suggest a genetic contribution to left ventricular (LV) diastolic filling; however, chromosomal locations harboring genes involved in impaired LV diastolic filling have not been reported. The aim of this study was to identify chromosomal regions contributing to variat...

BACKGROUND Three important determinants of left ventricular (LV) peak early diastolic filling rate, which is related directly to the magnitude of the transmitral pressure difference, are the rate of LV isovolumic pressure fall (T1/2), left atrial (LA) pressure at mitral valve opening (X1), and end-systolic volume (ESV). METHODS AND RESULTS To delineate the relative degrees to which these fact...

Background. Three important determinants of left ventricular (LV) peak early diastolic filling rate, which is related directly to the magnitude of the transmitral pressure difference, are the rate of LV isovolumic pressure fall (T1/2), left atrial (LA) pressure at mitral valve opening (XI), and end-systolic volume (ESV). Methods and Results. To delineate the relative degrees to which these fact...

To estimate the effects of diltiazem on the left ventricular diastolic abnormalities in patients with hypertrophic cardiomyopathy, transmitral flow velocity during diastole was studied before and immediately after dynamic leg exercise with the pulsed Doppler technique combined with two-dimensional echocardiography. Seventeen patients with hypertrophic cardiomyopathy and 24 apparently healthy me...

The major cause of late mortality and morbidity after prosthetic valve replacement is thromboembolism. The nidus for initiation of thrombus formation has been blood metal interfaces, and a new valve--the St Jude prosthesis--has therefore been developed without any metal components. We have assessed echocardiographically in 27 patients the effects of this valve on left ventricular filling charac...

UNLABELLED A cutaneous force-frequency relation recording system based on first heart sound amplitude vibrations has been recently validated. Second heart sound can be simultaneously recorded in order to quantify both systole and diastole duration. AIMS 1- To assess the feasibility and extra-value of operator-independent, force sensor-based, diastolic time recording during stress. METHODS W...

conclusions instillation of ropivacaine 0.2% (30 ml) within tubeless pcnl surgery does not have a significant effect on postoperative pain relief and improvement of pef within 6 hours after the operation. results we found no difference in the mean pain severity score between the case and control groups 4 hours (p = 0.332) and 6 hours (p = 0.830) after the operation. the mean pef at baseline was...
