There are about 428 clinical studies being (or have been) conducted in United Arab Emirates. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
This is a multicenter, prospective, single-arm observational non-interventional study (NIS), which will be conducted in various countries in the Middle East and India.
The use of intra coronary physiological assessment with fractional flow reserve (FFR) is nowadays the standard approach to define ischemia-inducing stenosis and guide myocardial revascularization strategy in patients with coronary artery disease. Further, FFR has been shown to be a strong and independent predictor of major adverse cardiac events after stent implantation. A lower value of FFR after stent implantation is associated with a worse clinical prognosis, without a clearly defined threshold above which clinical follow up are similar for all FFR values. Among 750 patients in the Fractional Flow Reserve Post-Stent Registry, the event rate was 29.5% in patients with FFR<0.80 compared to 9 4.9% in patients with FFR>0.95 (p<0.001). However, FFR remains poorly adopted in many cathlabs, partly because of procedural time, discomfort or sides effect during hyperemia, non-uniform adenosine response and economical constraints. This leads to the validation of resting indices (instantaneous wave-free ratio (iFR), diastolic pressure ratio (dPR), and resting full-cycle ratio (RFR) among others). Those indices evaluate coronary physiology without the use of maximal hyperemia and have 15 slightly different threshold compared to FFR (≤0.89 vs 0.80, for iFR and RFR, and FFR 16 respectively).In the VALIDATE RFR study, a head-to-head comparison of RFR and iFR from a retrospective analysis, diagnostic accuracy of RFR was 97.4% with an area under the curve 1 (AUC) of 99.6%. In the more recent RE-VALIDATE RFR study, 431 patients with 501 lesions 2 were prospectively evaluated for the diagnostic performance of RFR in all-comers patients. Compared to iFR, RFR achieved high diagnostic accuracy, sensitivity and specificity. These are the reasons why we designed a prospective, non-randomized, clinical trial, to better 18 explore the value of RFR before and after PCI in real live and after optimization by post dilation 19 in all-comers patients with coronary artery disease in the Middle East region..
For a pregnancy to occur, an euploid embryo at blastocyst developmental stage, a receptive endometrium and the synchrony of both is crucial. Many studies lately investigated the influence of the endometrial thickness and pattern on the artificial reproductive technology (ART) outcome, however, with conflicting results.
The purpose of the study is to assess the effects of selexipag on right ventricular (RV) function in participants with Pulmonary arterial hypertension (PAH).
The primary aim is to verify if camel milk consumption has an impact on the amount of Midazolam needed to achieve a satisfactory level of sedation for oocyte retrieval, compared to patients never having consumed camel milk.
Investigators will be comparing artificial (HRT) frozen-thawed embryo transfer cycles to correctly conducted spontaneous natural cycles after the transfer of a chromosomally normal embryo.
The investigators want to verify if advanced maternal age patients with a low Anti-Müllerian hormone (AMH) level may benefit from an early trigger time (compared to a late trigger).
To determine the impact of Midazolam levels in follicular fluid on morpho-kinetics and morpho-genetics. The reason to measure Midazolam levels in larger size follicles in this study is to maximize the chances to get a mature oocyte and therefore develop into a potential embryo to be analyzed.
To evaluate the influence of circadian rhythm on progesterone levels during follicular phase of natural cycle and during follicular phase of controlled ovarian stimulation during IVF.
The clinical characteristics, initial presentation, management, and outcomes of patients hospitalized with new-onset (first diagnosis) heart failure (HF) or decompensation of chronic HF are poorly understood worldwide. REPORT-HF is a global, prospective, and observational HF disease registry designed to characterize patient trajectories longitudinally during and following an index hospitalization for acute HF.
