Filter by:This is a single-center, double-blind, randomized controlled clinical trial comparing four groups: placebo conventional coronary artery bypass graft (CCABG) group, dexamethasone CCABG group, placebo off-pump coronary artery bypass (OPCAB) group, and dexamethasone OPCAB group. The primary outcomes of this study is comprised of presence of arrhythmia, major adverse cardiac events (MACE), myocardial infarction, stroke, renal failure, respiratory failure, inflammation, and death. These primary outcomes were assessed during the surgery, 18 hours post surgery, every day during the hospital stay, 14 days and 30 days post surgery.
The objective of the BIOSTEMI ES study is to assess the long-term clinical outcomes with the Orsiro ultrathin-strut biodegradable polymer sirolimus-eluting stent compared to the Xience thin-strut durable polymer everolimus-eluting stent up to 5 years of follow-up among patients with STEMI undergoing primary PCI, enrolled in the BIOSTEMI trial.
This traditional feasibility study aims to capture preliminary safety and effectiveness information on a near-final Investigational Device design to adequately plan the forthcoming pivotal study.
This study aims to determine whether the neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) can be used as predictors of coronary heart disease (CHD) in CKD patients undergoing dialysis at Moewardi General Hospital Surakarta. It was hypothesized that NLR and PLR, which have been identified as inflammatory biomarkers, would be significantly related to increased arotid intima-media thickness (CIMT) in CKD patients undergoing dialysis. This study is an observational analytic study using a cross-sectional approach conducted at department of renal-hypertension and hemodialysis unit in Moewardi General Hospital in Surakarta, Indonesia from January to July 2022.
Coronary Microvascular Dysfunction has been consistently shown to play a considerable role in pathophysiology of Ischaemia with non-obstructed coronary arteries (INOCA). While the both diagnoses are individually related to remarkably worse outcome, there is no available method to simultaneously determine INOCA-CMD endotypes in vessel level, during the invasive diagnosis. The investigators hereby hypothesize that, combined intracoronary electrocardiogram (IC-ECG) (considering the high sensitivity and specificity of IC-ECG for studied vessel-territory) and intracoronary doppler can simultaneously and successfully identify vessel specific coronary microvascular dysfunction and resulting ischemia, which may potentially enable immediate diagnosis and endotyping of CMD-INOCA subgroups during the invasive assessment of first ANOCA episode, obviating the need for further ischemia-studies such es SPECT, which have considerably higher costs and lower sensitivity. Major coronary arteries of patients aged between 18 - 75 without obstructing coronary artery disease who have previously documented ischemia with non-obstructed coronary arteries (INOCA) via coronary angiogram and myocardial perfusion scan will be evaluated simultaneously with IC-ECG and intracoronary Doppler during rest and under adenosine induced hyperaemia. Performance of the combined system to identify Coronary Microvascular Dysfunction with structural and functional subgroups as defined by abnormal Coronary Flow Reserve (CFR) and Hyperemic Microvascular Resistance (HMR) and Ischemia in downstream territories of same vessel area (as defined by perfusion scan) is intended to be determined. The investigators also intend to interrogate the possible relationship between dynamic changes in IC-ECG parameters and invasively obtained intracoronary hemodynamic data.
All preoperative cardiac medications will be continued till the morning of the surgery, except angiotensin converting enzyme inhibitors. Patients will be pre-medicated with intramuscular morphine at 0.1 mg.kg-1 one hour before surgery. Upon arrival to the operating room, Initial monitoring included five lead electrocardiograms, non-invasive blood pressure, and pulse oximetry. At the attending anesthetists discretion, intravenous midazolam (0.05 mg/kg) will be administered for anxiolysis. Under local anesthesia an arterial line will be placed in the right radial artery and central venous line will be placed in the right internal jugular vein. Before induction of anesthesia for all study patients, Electrical cardiometry device (ICON; Cardiotonic, Osypka; Berlin, Germany) will be applied to the patient through 4 electrodes at the following sites: Below the left ear, Above the midpoint of the left clavicle, Left mid-axillary line at level of the xiphoid process and 5 cm inferior to the third electrode. Stroke volume variability (SVV) was measured while patient maintaining standard calm breathing at 8 breath/minute for one-minute. Patients with SVV less than 13% will be excluded from the study. Thus, all patients included will be considered fluid responders[5]. The baseline data in the form of heart rate, systolic, diastolic, and mean systemic arterial pressures, CO, CI, SV, SVI, SVV, SVR, and SVRI will be recorded during the study period in all the patients. Patients will then be randomly divided into two groups; control group will receive nothing before induction, while patients in volume loading group will receive volume loading of 8ml/kg Ringer acetate over 10 minutes. The volume loading will be repeated until SVV would be below 13%. The volume loading would be given by an anesthesia resident not involved in data collection. For induction, Patients in both groups will receive 3 mcg/kg of fentanyl. Then in all patients, propofol will be injected slowly at 1.5 mg/kg in 0.25 mg/kg increments every 20 s till clinical loss of consciousness. Clinical loss of consciousness (defined as no response to auditory command) will be assessed by asking the patients repeatedly every 20 s to open their eyes. After loss of consciousness, atracurium 0.5 mg/kg will be administered to facilitate tracheal intubation. The stress response to laryngoscopy and tracheal intubation is secondary to marked increase in sympathetic activity and manifested in general as tachycardia and hypertension and will be managed with increments 0..25mcg fentanyl. Hemodynamic changes; 20 beats/ minute or 20 mmHg difference in heart rate and blood pressure respectively were considered to be significant. Anesthesia will be maintained by isoflurane (1-1.2 %). Patients will be mechanically ventilated to have target of PO2 above 300mmhg and PCO2 between 35-40mmg. Any episode of hypotension (defined as mean arterial pressure [MAP] < 80% of the baseline reading and/or MAP <60 mmHg) will be managed by 5 mcg norepinephrine (which could be repeated if hypotension persists for 2 minutes). If bradycardia occurred (defined as heart rate less than 50 bpm), it will be managed by IV atropine bolus (0.5 mg). Hemodynamic data will be recorded 1-minte before the induction, 1-and 2-minutes after loss of consciousness, 1-minutes after intubation, then every 2-minutes for 15-minutes after intubation., the end point of the present study. Throughout this period the lungs will be mechanically ventilated with 50% air-oxygen mixture, to maintain an end-tidal carbon dioxide between 35 and 40 mmHg.
To evaluate the feasibility of a 6-month multidisciplinary program to reverse prediabetes in adults with coronary heart disease using the Mediterranean diet, intermittent fasting and exercise.
The purpose of the trial is to examine whether treatment with dapagliflozin plus insulin as compared with insulin alone (basal-bolus insulin) will result in similar blood glucose control and similar rate of complications in patients with diabetes, who are admitted to a hospital in a noncritical setting
The study is designed as a retrospective, international, multi-center cohort study to evaluate Steelex® Sternum Set for sternum closure. The data from 2 clinics located in Germany and Spain participating in the "OPTICABG" as well as in the "PREMIVALVE" study will be used for assessment. Only patients receiving a complete or a partial sternotomy closed with Steelex® Sternum Set will be included in the analysis. "OPTICABG" patients were followed up 3 months after surgery and "PREMIVALVE" patients until 6 months after surgery. Adverse Events (AE) / Serious Adverse Events (SAE)(e.g. surgical site infection, sternum stability, stroke, myocardial infraction, death etc.) reported in both studies will be used for the STERCCAS analysis.
The investigators aimed to identify the value of concordance between the diastolic hyperemia-free ratio (DFR) and fractional flow reserve (FFR) during pre-interventional and post-interventional period using a 0.014" COMET II Pressure Guidewire
