Among patients with stable coronary disease and moderate or severe ischemia, whether clinical outcomes are better in those who receive an invasive intervention plus medical therapy than alone is uncertain.
To evaluate the diagnostic usefulness of positron emission tomography (PET) with fluorine-18 fluorodeoxyglucose (FDG) in patients primary colorectal carcinomas.Forty-eight biopsy-proved (n = 44) or high clinical suspicion for 4) cancer underwent whole-body PET after intravenous administration 10 mCi (370 MBq) FDG. FDG results were correlated computed tomographic (CT), surgical, and histopathologic findings.PET depicted all known intraluminal carcinomas 37 (including two situ carcinomas)...
The ISCHEMIA trial (International Study of Comparative Health Effectiveness With Medical and Invasive Approaches) compared an initial invasive versus conservative management strategy for patients with chronic coronary disease moderate or severe ischemia, no major difference in most outcomes during a median 3.2 years. Extended follow-up mortality is ongoing.
Background: Whether an initial invasive strategy in patients with stable ischemic heart disease and at least moderate ischemia improves outcomes the setting of a history failure (HF) or left ventricular dysfunction (LVD) when ejection fraction is ≥35% but <45% unknown. Methods: Among 5179 participants randomized into ISCHEMIA (International Study Comparative Health Effectiveness With Medical Invasive Approaches), all whom had (LVEF) ≥35%, we compared cardiovascular by treatment HF/LVD...
Background: Among patients with diabetes and chronic coronary disease, it is unclear if invasive management improves outcomes when added to medical therapy. Methods: The ISCHEMIA (International Study of Comparative Health Effectiveness Medical Invasive Approaches) trials (ie, ISCHEMIA–Chronic Kidney Disease) randomized disease an (medical therapy + angiography revascularization feasible) or a conservative approach alone failed). Cohorts were combined after no trial-specific effects observed....
In 42 patients with acute anterior myocardial infarction (AMI), we studied the course of Q-wave development and R-wave reduction during first 48 hours after onset chest pain. We used precordial mapping in relation to clinical features, hemodynamic measurements enzyme release. Q waves developed within 6-14 (mean 9 hours) symptoms. amplitudes demonstrated nearly a reflected image: They reduced abruptly 5-11 pain, coinciding ST-segment elevation. 14 (group A, 33%) initial QRS alterations, there...
Background: Patients with significant (≥50%) left main disease (LMD) have a high risk of cardiovascular events, and guidelines recommend revascularization to improve survival. However, the impact intermediate LMD (stenosis, 25%–49%) on outcomes is unclear. Methods: Randomized ISCHEMIA (International Study Comparative Health Effectiveness With Medical Invasive Approaches) participants who underwent coronary computed tomography angiography at baseline were categorized into those (25%–49%)...
The value of the Selvester and Cardiac Infarction Injury Scores was assessed in a randomized, placebo-controlled study intravenous recombinant tissue plasminogen activator (rt-PA) 721 patients with acute myocardial infarction. Electrocardiograms (ECG) obtained at admission, 6 h 10 to 22 days after start therapy were analysed. Patients prior infarction or QRS duration ≧ 120 ms excluded, leaving 322 rt-PA group 333 placebo group. Cumulative 72-h release alpha-hydroxybutyrate dehydrogenase...
BACKGROUND: The relationship between the extent and severity of stress-induced ischemia anatomic coronary artery disease (CAD) in patients with obstructive CAD is multifactorial includes intensity stress achieved, type testing used, presence prior infarction, collateral blood flow, plaque characteristics, microvascular disease, vasomotor tone, genetic factors. Among chronic participants site-determined moderate or severe ischemia, we investigated associations on computed tomography...
Background The long-term outcome of impaired regional myocardial contractility after successful single vessel percutaneous transluminal coronary angioplasty (PTCA) was angiographically evaluated. Methods ventriculograms prior to PTCA and at mid-term follow-up 250 consecutive patients with elective single-vessel were analyzed. One hundred demonstrated wall motion abnormalities in the vessel-dependent region by visual analysis before PTCA. study group comprised 66 these 100 (four women, 62...
