Article Synopsis
  • The study looked at patients who had heart surgery (CABG) and whether they joined a trial testing two treatment options for heart problems.
  • Out of 217 patients, most either didn't want to join or weren't eligible, with 60 actually participating in the trial and 73 in a registry.
  • In the end, both groups had similar long-term health results, but those in the registry had worse initial health issues compared to those in the trial.

Background: The benefits of routine invasive management in patients with prior coronary artery bypass grafts presenting with non-ST elevation acute coronary syndromes are uncertain because these patients were excluded from pivotal trials.

Methods: In a multicenter trial, non-ST elevation acute coronary syndromes patients with prior coronary artery bypass graft were prospectively screened in 4 acute hospitals. Medically stabilized patients were randomized to invasive management (invasive group) or noninvasive management (medical group).

Background: In patients with acute non-ST-elevation myocardial infarction (NSTEMI), coronary arteriography is usually recommended; but visual interpretation of the angiogram is subjective. We hypothesized that functional assessment of coronary stenosis severity with a pressure-sensitive guide wire (fractional flow reserve [FFR]) would have additive diagnostic, clinical, and health economic utility as compared with angiography-guided standard care.

Methods And Design: A prospective multicenter parallel-group 1:1 randomized controlled superiority trial in 350 NSTEMI patients with ≥1 coronary stenosis ≥30% severity (threshold for FFR measurement) will be conducted.

Background: Angiotensin Converting Enzyme (ACE) inhibitors improve outcomes in patients with coronary artery disease irrespective of the status of the left ventricle. In the presence of functionally significant renovascular disease, ACE inhibitors often cause deterioration of renal function leading to their withdrawal.

Design: Observational study with 6 months prospective follow-up.

Background: The safety and efficacy of direct coronary artery stenting without predilatation using drug eluting stents has not been firmly established. Concerns have been raised that this technique may be associated with increased risk of immediate and short term complications.

Methods: 68 consecutive patients with chronic stable angina and angiographically proven single vessel disease were randomised to undergo either direct coronary artery stenting or stenting after balloon predilation.

Aims: Collateral arteries are a common but inconsistent finding in coronary heart disease (CHD). We endeavoured to review the methods for coronary artery collateral assessment, the predictors and clinical importance of collateral blood flow, and the potential for therapeutic augmentation of collateral anastomoses.

Methods And Results: While many methods have been used to assess collateral blood flow only a few have been formally validated.

Objective: To study the influence of clinical and angiographic factors on global and regional left ventricular (LV) function after rescue percutaneous coronary intervention (PCI) in acute myocardial infarction (AMI).

Methods: We performed repeat cardiac catheterization in 102 patients who underwent rescue PCI at our centre. Eighty-two patients had suitable baseline and follow-up ventriculograms, which were analyzed offline by an automated edge detection technique.
