Insights
Chinese and South Asian heart failure patients show distinct clinical profiles compared to other groups. Understanding these differences is key for tailored prevention and management strategies in diverse populations.
Area of Science:
- Cardiology
- Public Health
- Health Disparities
Background:
- Heart failure prevalence is rising globally.
- Ethnic minorities are an increasing proportion of Western populations.
- Clinical profiles of ethnic minorities with heart failure remain understudied.
Purpose of the Study:
- To compare clinical features of Chinese and South Asian heart failure patients.
- To contrast these groups with non-Chinese/non-South Asian patients.
- To examine patients within shared healthcare systems and social environments.
Main Methods:
- Analysis of patient records from 2 specialized heart failure clinics in Ontario, Canada.
- Inclusion of 1,671 heart failure patients.
- Identification of 181 Chinese (11%) and 215 South Asian (13%) patients.
Main Results:
- Chinese patients had lower rates of prior myocardial infarction (MI), 3-vessel coronary disease, severe left ventricular dysfunction, and ACE inhibitor use compared to non-Chinese/non-South Asian (NCH/NSA) patients.
- South Asian patients exhibited higher rates of prior MI, 3-vessel coronary disease, and coronary revascularization compared to NCH/NSA patients.
- Significant variations in comorbidities, clinical characteristics, and treatment patterns were observed across ethnic groups.
Conclusions:
- Important differences exist in heart failure management among Chinese, South Asian, and NCH/NSA patient groups.
- Awareness of these ethnic-specific variations is crucial.
- Development of tailored strategies is necessary for effective heart failure prevention and management in diverse ethnic minority populations.
Objectives:
The purpose of our study was to compare the clinical features of Chinese and South Asians, the 2 largest minority populations in Canada, with non-Chinese/non-South Asian (NCH/NSA) patients managed in common social macroenvironments and healthcare systems.
Background:
Heart failure is an increasingly prevalent condition. Although ethnic minorities comprise a growing proportion of the population in Western countries, the clinical profiles of ethnic minorities with heart failure are largely unknown.
Methods:
We analyzed records of patients with heart failure managed in 2 specialized clinics in Ontario, Canada. Of the 1,671 patients, 181 (11%) were identified as Chinese and 215 (13%) as South Asian.
Results:
Our analyses showed that fewer Chinese patients were found to have a history of myocardial infarction (MI) (30% vs. 52%), 3 occluded/stenosed coronary vessels on angiogram (47% vs. 51%), grade 3 or worse left ventricular dysfunction (22% vs. 42%), and a prescription of angiotensin-converting enzyme inhibitors (42% vs. 63%) compared with their NCH/NSA counterparts. In contrast, South Asian patients more frequently had a past history of an MI (70% vs. 52%), 3 occluded/stenosed coronary vessels on angiogram (68% vs. 51%), and treatment with coronary revascularizations (55% vs. 40%) compared with NCH/NSA patients.
Conclusions:
Our study demonstrates important differences in comorbid conditions, clinical characteristics, and treatment patterns among Chinese and South Asian patients compared with NCH/NSA patients with heart failure. Awareness of these differences will help to develop differential strategies necessary to prevent and manage heart failure among ethnic minority groups.
