Comparative Study
Acute coronary syndromes--the prognostic impact of hypertension, diabetes and its combination on long-term outcome.
Knowledge about the simultaneous influence of diabetes and hypertension on outcome among patients with ischemic heart disease is limited. The objective of this survey was to describe the characteristics, treatment and outcome among patients with acute coronary syndromes (ACS) in relation to previous history of hypertension (HT), diabetes mellitus (DM) or a combination of the two. ⋯ ACS patients with a history of HT and DM had a higher age-adjusted, long-term mortality risk than ACS patients without such a history. DM appeared to be more strongly associated with mortality than HT, but its combination was additive.

Letter Comparative Study
Comparison of incidence and angiography patterns in definite thrombosis between drug-eluting and bare-metal stents.
Stent thrombosis is a feared complication of percutaneous coronary intervention due to its catastrophic consequences. We analysed the incidence of angiographically-confirmed thrombosis in 5011 consecutive patients treated with drug-eluting stents or bare-metal stents. Although the incidence of thrombosis was similar between the two groups (0.8%), angiographically-documented late thrombosis was a relatively unusual complication after implantation of either stent, though it was more common with drug-eluting stents than bare-metal stents (0.25 vs. 0.06%, P=.03).
