ABSTRACT
OBJECTIVE: To study the temporal and gender trends in age-standardised hospitalisation rates, in-hospital mortality rates and indicators of health service use for acute myocardial infarction (AMI), and the sub-categories, ST elevation MI (STEMI) and non-ST elevation MI (NSTEMI), in Ireland, 1997-2008. DESIGN, SETTING, PATIENTS: Anonymised data from the hospital inpatient enquiry were studied for the ICD codes covering STEMI and NSTEMI in all 39 acute hospitals in Ireland over a 12-year period. Age standardisation (direct method) was used to study hospitalisation and in-hospital mortality rates. Joinpoint regression analysis was undertaken to identify significant inflection points in hospitalisation trends. MAIN OUTCOME MEASURES: Age-standardised hospitalisation rates, in-hospital mortality and indicators of health service use (length of stay, bed days) for AMI, STEMI and NSTEMI patients. RESULTS: From 1997 to 2008, hospitalisation rates for AMI decreased by 27%, and by 68% for STEMI patients (test for trend p<0.001), and increased by 122% for NSTEMI, (test for trend p<0.001). The mean age of male STEMI patients decreased (p<0.01), while those for the remaining groupings of AMI and subcategories increased. The proportion of males increased significantly for STEMI and NSTEMI (p<0.001). In-hospital mortality decreased steadily (p=0.01 STEMI, p=0.02 NSTEMI), as did median length of stay. CONCLUSIONS: The authors found a steady decrease in hospitalisation rates with AMI, and a shift away from STEMI towards rising rates of NSTEMI patients who are increasingly older. In an ageing population, and with increasing survival rates, surveillance of acute coronary syndrome and allied conditions is necessary to inform clinicians and policy makers.

BACKGROUND: Heartwatch is a secondary prevention programme of coronary heart disease (CHD) in primary care in Ireland. The aim was to further examine the effect of the Heartwatch programme on cardiovascular risk factors and treatments of patients with a follow-up of 3.5 years. DESIGN: Prospective cohort study of 12,358 patients with established CHD (myocardial infarction, percutaneous cardiac intervention, coronary artery bypass graft) recruited by participating general practitioners; patients invited to attend on a quarterly basis, with continuing care implemented according to defined clinical protocols. METHODS: Changes in risk factors and treatments at 1, 2, 3 and 3.5-year follow-up from baseline were made using paired t-test for continuous and McNemar's test for categorical data. RESULTS: Important changes in systolic and diastolic blood pressure, total and low-density lipoprotein cholesterol and smoking status were observed at 1, 2, 3 and 3.5 years (P < 0.0001) with significant increase in proportions of patients within the target. However, changes in body mass index were small, with no significant improvement in waist circumference. There was a significant increase in prescription of secondary preventive medications and good patient compliance. Males were more likely to be within the target for systolic blood pressure, total cholesterol, waist circumference and exercise level at 3.5 years, but less likely for body mass index. CONCLUSION: Studies of cardiac rehabilitation without any follow-up programmes show that over time patients revert in part to previous lifestyle habits; this primary care-delivered programme has shown sustained improvements in major risk factors, particularly smoking, blood pressure and cholesterol, and treatments for CHD. Weight management presents a greater challenge.

INTRODUCTION: The aim of this study was to determine how routinely recorded data could predict early the likelihood of patient non-adherence to a primary care-delivered secondary prevention programme for established coronary heart disease (CHD), with patients with CHD (10,851) invited to attend four times per year. METHOD: Non-adherence was defined as attending no more than three GP visits ever. The study sample was selected to allow a possible two-year recorded follow-up period in which patients could take up invitations. Administrative recordings of visit dates and intervals between visits, baseline results of key parameters and early changes were examined using logistic regression to determine independent predictors of non-adherence. RESULT: Longer interval between early visits, no family history of CHD, smoking and being outside target for exercise at baseline were independently associated with non-adherence. CONCLUSION: Early identification by GPs of those who fail to attend on time or who defer appointments, in addition to persistence of lifestyle factors unchanged by a prior serious cardiac event should serve as a warning sign that targeted interventions to maintain adherence in primary care-delivered secondary prevention programmes are necessary.

AIMS: Systematic registration of data from clinical practice is important for clinical care, local, national and international registries, and audit. Data to be collected for these different purposes should be harmonized. Therefore, during Ireland's Presidency of the European Union (EU) (January to June 2004), the Department of Health and Children worked with the European Society of Cardiology, the Irish Cardiac Society, and the European Commission to develop data standards for clinical cardiology. The Cardiology Audit and Registration Data Standards (CARDS) Project aimed to agree standards for three modules of cardiovascular health information systems: acute coronary syndromes (ACS), percutaneous coronary interventions (PCI), and clinical electrophysiology (pacemakers, implantable cardioverter defibrillators, and ablation procedures). METHODS AND RESULTS: Data items from existing registries and surveys were reviewed to derive draft data standards (variables, coding, and definitions). Variables common to the three modules include demographics, risk factors, medication, and discharge and follow-up data. Modules about a procedure contain variables on the lesion, the device, and medication during the procedure. The ACS module includes presenting symptoms, reperfusion and acute treatments, and procedures in hospital and at follow-up. CONCLUSIONS: The data standards were discussed and adopted at a conference involving EU member states in Cork, Ireland, in May 2004. After a pilot study, the standards will be disseminated to stakeholders throughout Europe.
