Indicators Of Cardiac Autonomic Dysfunction Associated With Chronic Hyperglycemia: Implications On Vascular Surrogates And Heart Failure, Yap-Hang Chan, Bernard Man-Yung Cheung, Hung-Fat Tse
Journal of the Hong Kong College of Cardiology
Background: Limited data exist on the role of chronic hyperglycemia-related cardiac autonomic dysfunction in incident heart failure (HF). We investigated the relations of resting heart rate (HR) and PR interval with chronic hyperglycemia, and effects on new-onset HF.
Methods: We prospectively studied 550 patients with prior coronary disease, ischemic stroke and/ or type 2 diabetes. Incident HF was ascertained. Heart rate-PR interval dissociation was defined as counter-physiological co-occurrence of increased PR interval (>mean; 173.3ms) and increased resting HR (>mean; 64.4 beats/min).
Results: Over 63 ±11 months, 6.7% patients developed new-onset HF. Resting HR³75bpm was independently predictive of new-onset …

Percutaneous Revascularisation In Diabetic Patients With Coronary Artery Disease, Wai-Hong Chen, Chu-Pak Lau
Journal of the Hong Kong College of Cardiology
Diabetic patients with coronary artery disease are associated with an unfavourable long-term outcome. Surgical revascularisation on top of medical therapy has been shown to confer survival benefit in patients with mutivessel and left main disease. With the emergence of the percutaneous approach of revascularisation, several clinical trials have been conducted to compare these two modalities of treatment. Consistent results were demonstrated in the diabetic subgroup that coronary artery bypass grafting is superior to balloon angioplasty in preventing late adverse cardiac event. With the advancement of percutaneous technique using coronary stenting as the predominant mode of catheter based revascularisation, the latest …
