Journal of the Hong Kong College of Cardiology

Immune checkpoint inhibitors (ICIs), though revolutionizing cancer care, are well known to cause a diverse array of autoimmune side effects termed immune-related adverse events (IRAEs). ICI Myocarditis is a rare manifestation of IRAE associated with high mortality. We report two cases of fulminant ICI myocarditis refractory to potent immunosuppressants. Our first patient received pembrolizumab for lymphoma, small cell lung cancer and renal cell carcinoma. After 13 doses of ICIs, he developed fulminant myocarditis with concomitant lower-motor neuron type facial nerve palsy. Despite receiving triple immunosuppressive therapies with pulse steroid, mycophenolate mofetil and basiliximab, his cardiac condition progressively worsened and eventually …

Background

The ‘inflamm-ageing’ phenomenon may worsen the prognosis of heart diseases including infective endocarditis (IE), while surgery may reduce inflammatory burden by direct removal of bacterial vegetation. This study aims to characterize the epidemiological and clinical features of surgical intervention for IE in Hong Kong in the past two decades.

Methods

All patients with incident IE from 2000-2019 in a territory-wide database were identified. We studied the trends in age-specific incidence of IE and identified the most significant contributors to 1-year all-cause death using the population attributable fraction (PAF). A propensity score approach was used to evaluate the benefits of …

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 …

What Should Patients Know About Self Blood Pressure Measurement? A Review Article, Sau-Nga Fu

Journal of the Hong Kong College of Cardiology

Many people measure their blood pressure (BP) outside doctors’ offices with a common goal of concerning their health status. Self-BP monitoring devices are widely accessible as health care products or available in different community institutes. Patients often seek their doctors’ advice on their BP readings in our daily practice. Current international guidelines recommend that correct self-BP measurement with validated devices can enhance patients’ self-management and drug compliance, improving overall BP control. While most of the clinicians were supportive of their patients’ efforts, they were also concerned about the validity and reliability of the out-of-office BP readings. How can we effectively …
