Given the results of the BARI and ARTS I trials and a meta-analysis, coronary artery bypass surgery has been preferred to percutaneous coronary intervention in diabetics with multivessel coronary artery disease requiring hypoglycemic treatment and in whom internal mammary artery grafts can be used. This approach was strongly recommended in a 2002 ACC/AHA Task Force on the management of patients with acute coronary syndrome. But, these recommendations were made before the availability of drug-eluting stents. We strongly believe that the ongoing, multi-centre FREEDOM, CARDia and SYNTAX trials will elucidate the optimal revascularization strategy for diabetic patients with multivessel disease in the near future.

Paroxysmal atrioventricular block and right coronary artery stenosis without acute myocardial infarction.
Paroxysmal atrioventricular block is an ill-defined entity, previously described in sporadic cases in association with vasovagal reaction, coronary angiography and distal conduction disease. The occurrence of atrioventricular block in acute inferior wall myocardial infarction is related to the presence of an important right coronary artery that is occluded, the recanalisation of this vessel leads often to rapid regression of the block that is no longer pejorative. ⋯ Coronary angiography revealed significant right coronary artery stenosis. Percutaneous transluminal coronary angioplasty with implantation of stent was successfully performed.

Citalopram induced torsade de pointes, a rare life threatening side effect.
Acquired Long QT syndrome is a disorder caused by medications, electrolyte imbalances, and drug interactions. This syndrome is associated with an increased risk of a characteristic life-threatening cardiac arrhythmia, known as torsade de pointes (TdP). ⋯ After discontinuation of citalopram, the QT/QTc interval normalized after 3 days and resolved further episodes of TdP. Patients on citalopram should be monitored closely for QT/QTc interval to prevent torsade de pointes.

In-stent restenosis and thrombosis 41 months after drug-eluting stent implantation.
Evidence indicates that very late stent thrombosis (>1 year) occurs more frequently in drug-eluting stents than in bare metal stents after discontinuation of clopidogrel. We present a case of an 83 year old man with an LAD in-stent thrombosis 41 months after stenting with a sirolimus-eluting stent in whom clopidogrel was discontinued after 6 months based on these days' guidelines. ⋯ The patient was discharged after recovery and had no recurrence of stent thrombosis in one month follow-up. We recommended indefinite dual antiplatelet therapy with aspirin and clopidogrel.

Letter Comparative Study
Is high body mass index associated with increased risk of groin complications using manual compression after diagnostic coronary angiography?
There is a common perception that high body mass index (BMI) is associated with an increased risk of bleeding complications at the site of femoral puncture when manual compression is used for achieving hemostasis. Because of lack of evidence to support or refute this, we conducted a study to assess whether raised BMI is associated with increased risk of groin complications. 15 cases of groin complications after manual compression over 2 years and 40 controls were each divided into 3 groups according to BMI. Baseline characteristics of cases and controls were similar. High BMI was not found to be associated with increased risk of groin complications, suggesting that manual compression is safe and effective in patients with raised BMI.
