Carotid endarterectomy remains the standard revascularization technique for the prevention of ischemic stroke resulting from severe carotid stenosis. Surgery is highly beneficial in patients with a symptomatic stenosis of 70% or greater that is not a total or near-total occlusion. The benefit becomes more diluted in patients with a symptomatic 50-69% stenosis, and surgery has no effect, or even increases the risk of stroke, in those with a less than 50% stenosis. ⋯ Decision-making must take individual factors into consideration, particularly in patients with an asymptomatic (60-99%) or a moderate (50-69%) symptomatic carotid stenosis, so that the risk-benefit ratio of surgery can be optimized. Current data do not support the preferential use of carotid stenting over carotid endarterectomy in patients with a symptomatic or asymptomatic carotid stenosis who are good candidates for surgery. In those who are not good surgical candidates, carotid stenting might be equivalent to surgery, but whether or not any form of carotid revascularization is superior to medical treatment alone remains unknown.

Some patients, such as Jehovah's Witnesses, refuse to use blood products, which can make it difficult to achieve the same outcomes as in the general population. The objective of this study was to determine whether clinical characteristics and surgical outcomes in Jehovah's Witnesses undergoing cardiac surgery are similar to those in other patients. ⋯ The clinical characteristics of Jehovah's Witnesses were similar to those of the control group. The complication rate was also similar in these patients, though the number of hours of mechanical ventilation was less, 24-hour bleeding was less, and the hospital stay was shorter. Mortality was similar in the two groups.

Kidney failure is more prevalent in patients with ischemic heart disease than in the general population. A high serum creatinine level is known to be a predictor of an adverse outcome in acute coronary syndrome. The aim of this study was to investigate the clinical significance of the glomerular filtration rate in patients with acute coronary syndrome and a normal baseline creatinine level. ⋯ In patients with acute coronary syndrome and a normal creatinine level on admission, estimation of the glomerular filtration rate provided important information on short-term prognosis. This parameter should be included in the risk assessment of patients with normal serum creatinine levels.

We carried out transcatheter procedures to close postinfarction ventricular septal defects (PIVSDs) in 19 patients: two had recanalization after surgical closure, and 17 had a primary PIVSD. In three of the latter patients, who had acute PIVSDs, the procedure was carried out in the first 3 weeks after infarction; in the 13 patients with subacute PIVSD, it was carried out 3.5-12 weeks after infarction. ⋯ The procedure was successful in 14 patients: in 11 with subacute PIVSD, one with chronic PIVSD, and two with postsurgical PIVSD. Transcatheter closure of PIVSDs using an Amplatzer atrial septal occluder is probably the treatment of choice in patients undergoing surgery more than 3.5 weeks after myocardial infarction and in those with recanalization after previous surgical closure.
