Feasibility of transradial coronary angiography and angioplasty in Chinese patients.

OBJECTIVE: To assess the clinical applicability, efficacy, and safety of coronary angiography and angioplasty via a transradial approach in local Chinese patients. DESIGN: Prospective case series. SETTING: Regional hospital, Hong Kong. PATIENTS: All patients undergoing coronary angiography and coronary angioplasty between 1 January and 30 June 2004. INTERVENTIONS: Transradial coronary angiography and coronary angioplasty. MAIN OUTCOME MEASURES: Feasibility, success rate, and complications. RESULTS: A total of 268 coronary angiographies (62% of all coronary angiographies) and 118 coronary angioplasties (48% of all coronary angioplasties) were performed via a transradial approach. The procedural success rate for coronary angiography was 93.7% with a mean duration of 21.8 (standard deviation, 13.5) minutes compared with 17.9 (10.0) minutes for angiography via a femoral approach. Most (99%) patients were free from any complications. Of those patients who underwent elective transradial coronary angiography in the morning, 64% were discharged on the same day. Comparison of data in the first half of the study period with those in the second half revealed a significant increase in the percentage of coronary angiographies performed via a transradial approach (from 52% to 73%, P<0.0001), and an improved procedural success rate (from 91.5% to 95.3%, P=0.1). For transradial coronary angioplasty, the procedural success rate was 98%. A total of 246 lesions (2.08 lesions per patient) were treated with no procedure-related complications. CONCLUSIONS: Transradial coronary angiography and angioplasty are feasible in a significant proportion of local Chinese patients and achieve a high success rate and low complication rate. It tends to prolong procedural duration, but improves patients' comfort and permits earlier ambulation and discharge. The procedural success rate improves with accumulating experience.

Risk factors for injury to married women from domestic violence in Hong Kong.

OBJECTIVE: To examine risk factors for injury to married women from domestic violence in Hong Kong. DESIGN: Case control study. SETTING: Regional public hospital, Hong Kong. PATIENTS: All married women aged 18 to 60 years who attended an accident and emergency department for treatment of a domestic violence injury from January 2004 to June 2005. MAIN OUTCOME MEASURES: Social and health characteristics of abused women and their husbands. RESULTS: A total of 293 cases were compared to 313 controls. Eight predictive variables were found to be significant by univariate analysis: woman who is a new immigrant (P = 0.003), woman with no job (P = 0.019), husband with low educational level (P < 0.001), presence of extramarital affairs (P < 0.001), husband's unemployment (P < 0.001), husband's alcohol abuse (P < 0.001), husband's illicit drug abuse (P = 0.032), husband's mental illness (P < 0.001). Five factors were found to be significant in a logistic regression analysis: husband with a low educational level (nil to primary) [adjusted odds ratio = 2.78; 95% confidence interval, 1.149-6.727], husband unemployed (adjusted odds ratio = 9.031; 95% confidence interval, 5.163-15.796), presence of extramarital affairs (adjusted odds ratio = 5.218; 95% confidence interval, 2.899-9.395), husband's alcohol abuse (adjusted odds ratio = 6.089; 95% confidence interval, 3.460-10.716), husband's mental illness (adjusted odds ratio = 9.443; 95% confidence interval, 2.351-37.926). CONCLUSIONS: Several significant risk factors have been identified for injury incurred during domestic violence to married women in Hong Kong. It provides information useful for developing local preventive strategies.

Isolated ventricular non-compaction presenting with ventricular tachycardia.

Isolated ventricular non-compaction is a rare congenital cardiomyopathy, manifested morphologically as prominent myocardial trabeculations and deep inter-trabecular recesses that communicate with the ventricular cavity. Heart failure is the most common presenting condition. Other manifestations include arrhythmia and cardioembolic events. This report is illustrative of isolated ventricular non-compaction in a 78-year-old woman. The diagnosis was made when she presented with ventricular tachycardia many years after a stroke. She subsequently underwent implantation of a cardioverter-defibrillator. This report documents an uncommon presentation of this disease entity in the oldest patient at presentation as yet reported in the literature.
