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 …

Pre-Participation Cardiovascular Screening In Athletes With A Focus On Asia, Tee Joo Yeo

Journal of the Hong Kong College of Cardiology

Pre-participation screening (PPS) in young competitive athletes aims to identify conditions associated with sudden cardiac death (SCD) in this population, with a view to appropriate management and potential mitigation of risk. A medical history questionnaire and physical examination are standard components of a PPS programme, whereas controversy still exists regarding mandatory utilisation of resting 12-lead electrocardiogram as a screening tool. Apart from a landmark study from Italy attributing the reduction of SCD rates in athletes to the implementation of a mandatory PPS programme, there remains no additional compelling evidence for similar outcomes to date. Nonetheless, comprehensive PPS programmes when carried …

A Coronary Rupture In The Left Anterior Descending Artery At Second Diagonal Artery Bifurcation Level In An Intervention With A Tryton Side Branch Stent, Muhammed Hakan Tas, Ziya Simsek, Yavuzer Koza, Zakir Lazoglu

Journal of the Hong Kong College of Cardiology

Percutaneous coronary intervention (PCI) for bifurcation lesions (BLs) is considered high risk due to increased procedural adverse events when compared to non-bifurcation lesion. Dedicated bifurcation stents, specifically designed to allow minimally traumatic implantation in the main vessel and/or side branch while providing adequate scaffolding of the side branch ostium may offer an advantage over utilization of conventional stents. Coronary perforation as a complication of PCI is a rare but potentially lethal complication that is associated with a high rate of morbidity. Coronary artery perforation during PCI has been reported repeatedly. To our best knowledge perforation in a BL, PCI with …

Drug Eluting Stent: A Major Advance In Fighting Coronary Artery Restenosis, Yuk-Kong Lau

Journal of the Hong Kong College of Cardiology

Since the first use of coronary angioplasty in 1977, there have been major growth and development in percutaneous coronary intervention (PCI). Due to the advances in techniques, experiences, devices, and newer potent antiplatelet and antithrombotic medications, PCI is increasingly performed in highly complex and high risk patients with a reasonably low complication rate. Coupled with reduced discomfort, shorter hospital stay and recovery time, it has far outnumbered the volume of coronary artery bypass surgery. Currently, 1.7 million PCI procedures are performed annually worldwide with increases by 15-20% per year the last decade.

The Post-Madit Ii Era: Icd For All Post-Infarct Patients With Moderate To Severe Left Ventricular Dysfunction?, Kathy Lai-Fun Lee, Chu-Pak Lau

Journal of the Hong Kong College of Cardiology

Device therapy has become the preferred treatment for patients who have survived sudden cardiac death. Throughout the last decade, large-scale randomized clinical trials have provided consistent evidence on the clinical efficacy of device therapy. ICD is proven to be superior to anti-arrhythmic drugs in patients with structural heart diseases who suffer from haemodynamically significant ventricular arrhythmias. The role of ICD in primary prevention of sudden death in selected patients with coronary artery disease and left ventricular dysfunction is also widely established after the Multicenter Automatic Defibrillator Implant Trial (MADIT) and the Multicenter Unsustained Tachycardia Trial (MUSTT).

Role Of Signal-Averaged Ecg In Predicting Results Of Flecainide Provocation Test Used In Family Screening For Brugada Syndrome, Ngai-Shing Mok, Chi-Chung Choy, Ngai-Yin Chan, Amy Ho

Journal of the Hong Kong College of Cardiology

Brugada syndrome (BS) is an inherited arrhythmogenic disease with an autosomal dominant mode of inheritance. Flecainide provocation test (FPT) has been shown to be highly sensitive and specific in unmasking the Brugada ECG pattern in affected subjects. We sought to test if late potential (LP) in signal averaged electrocardiogram (SAECG) is helpful in predicting the results of FPT used in family screening for BS. The study included 17 asymptomatic Chinese subjects from 8 families (M:F 10:7, mean age 24.8±11.4 years) who have undergone family screening for BS. All screened subjects had a normal 12-lead ECG at baseline. None had structural …

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 …
