Stress hyperglycaemia is an independent predictor of left ventricular remodelling after first anterior myocardial infarction in non-diabetic patients.

Aims: Stress hyperglycaemia (SH) is associated with adverse outcome in patients with acute myocardial infarction (MI) but the mechanisms underlying this association are unknown. Our hypothesis was that SH on admission for acute MI may be associated with left ventricular (LV) remodelling.

Methods And Results: We analysed LV remodelling in 162 non-diabetic patients with anterior MI.

Effect of elevated heart rate preceding the onset of ventricular tachycardia on antitachycardia pacing effectiveness in patients with implantable cardioverter defibrillators.

The incorporation of antitachycardia pacing (ATP) into implantable cardioverter defibrillators (ICDs) has provided a better tolerated alternative to shocks. ATP has been shown to be effective in terminating approximately 80% to 90% of spontaneous ventricular tachycardia (VT) episodes. Although ATP is routinely used, little is known about predictors of ATP failure.

[Hyperthyroidism associated with pulmonary hypertension].

The association of pulmonary hypertension and polyendocrinopathies or connective tissue diseases has been reported by several authors. The causes of this form of pulmonary hypertension are not clear but an autoimmune process has often been proposed. The authors report a case of non-autoimmune hyperthyroidism and reversible pulmonary hypertension after total thyroidectomy and normalisation of thyroid function.
