Insights
The Heartwatch program improved key coronary heart disease (CHD) risk factors and treatments in primary care. However, further interventions are needed to address body mass index (BMI), waist circumference, and physical inactivity.
Area of Science:
- Cardiology
- Public Health
- Preventive Medicine
Background:
- The Heartwatch program, initiated in 2003, aligns with European guidelines for secondary prevention of coronary heart disease (CHD).
- This secondary prevention initiative operates within a primary care setting.
Purpose of the Study:
- To evaluate the impact of the initial two years of the Heartwatch program on cardiovascular risk factors and treatment strategies.
- To assess changes in patient outcomes and adherence to secondary prevention protocols.
Main Methods:
- A prospective cohort study design was employed, enrolling patients with established CHD into the Heartwatch program.
- Data from 11,542 patients across 470 general practices were collected electronically over two years.
- Statistical analyses included paired t-tests and McNemar's tests to compare baseline, 1-year, and 2-year follow-up data.
Main Results:
- Significant reductions were observed in systolic and diastolic blood pressure, total and LDL cholesterol, and smoking rates (P <0.0001).
- Limited improvements were noted for body mass index (BMI), waist circumference, and exercise levels.
- Prescription rates for statins, ACE inhibitors, and beta-blockers increased significantly during the study period.
Conclusions:
- The Heartwatch program successfully improved major CHD risk factors and treatment adherence.
- Enhanced interventions are necessary to target BMI, waist circumference, and physical inactivity.
- Treatment uptake has approached optimal levels, indicating program effectiveness in medication management.
Background:
Heartwatch, a secondary prevention programme in primary care was initiated in 2003, based on the second European Joint Task Force recommendations for secondary prevention of coronary heart disease (CHD). The aim was to examine the effect of the first 2 years of the Heartwatch programme on cardiovascular risk factors and treatments.
Design:
Prospective cohort study of patients with established CHD enrolled into the Heartwatch programme.
Methods:
Four hundred and seventy (20%) general practitioners nationwide participated in the programme, recruiting 11,542 patients with established CHD (earlier myocardial infarction, coronary intervention or coronary artery bypass surgery). Clinical data were electronically transferred by each general practitioner to a central database. Comparison of changes in risk factors and treatments at 1-year and 2-year follow-up from baseline were made using paired t-test for continuous and McNemar's test for categorical data.
Results:
Statistically significant changes in systolic blood pressure, diastolic blood pressure, total and low-density lipoprotien cholesterol and smoking status at 1 and 2 years (P <0.0001) were observed. Little or no improvements were shown for exercise, BMI or waist circumference. Increases in the prescribing of statins, angiotensin-converting enzyme inhibitors and beta-blockers over the course of the study were observed.
Conclusion:
The Heartwatch programme has demonstrated significant improvements in the main risk factors and treatments for CHD. More effective interventions are required to reduce BMI, waist circumference and physical inactivity in this population. The increases in treatment uptake are approaching the optimal levels in this population.
