Objectives
To compare the outcomes and safety of a rapid access chest pain clinic (RACPC) in Australia with those of a general cardiology clinic.
Design
Prospective comparison of the outcomes for patients attending an RACPC and those of historical controls.
Setting
Royal Hobart Hospital cardiology outpatient department.
Participants
1914 patients referred for outpatient evaluation of new onset chest pain (1479 patients seen in the RACPC, 435 patients previously seen in the general cardiology clinic).
Main outcome measures
Service outcomes (review times, number of clinic reviews); adverse events (unplanned emergency department re‐attendances at 30 days and 12 months; major adverse cardiovascular events at 12 months, including unplanned revascularisation, acute coronary syndrome, stroke, cardiac death).
Results
Median time to review was shorter for RACPC than for usual care patients (12 days [IQR, 8–15 days] v 45 days [IQR, 27–89 days]). All patients seen in the RACPC received a diagnosis at the first clinic visit, but only 139 patients in the usual care group (32.0%). There were fewer unplanned emergency department re‐attendances for patients in the RACPC group at 30 days (1.6% v 4.4%) and 12 months (5.7% v 12.9%) than in the control group. Major adverse cardiovascular events were less frequent among patients evaluated in the RACPC (0.2% v 1.4%).
Conclusions
Patients were evaluated more efficiently in the RACPC than in a traditional cardiology clinic, and their subsequent rates of emergency department re‐attendances and adverse cardiovascular events were lower.
Objectives: To assess the efficacy of a pro-active, absolute cardiovascular risk-guided approach to opportunistically modifying cardiovascular risk factors in patients without coronary ischaemia attending a chest pain clinic.
Background
The majority of patients attending chest pain clinics are found not to have a cardiac cause of their symptoms, but have a high burden of cardiovascular risk factors that may be opportunistically addressed. Absolute risk calculators are recommended to guide risk factor management, although it is uncertain to what extent these calculations may assist with patient engagement in risk factor modification.
Purpose
We sought to determine the usefulness of a proactive, absolute risk-based approach, to guide opportunistic cardiovascular risk factor management within a chest pain clinic.
Methods
This was a prospective, open-label, blinded-endpoint study in 192 enhanced risk (estimated 5-year risk ≥8%, based on Australian Absolute Risk Calculator) patients presenting to a tertiary hospital chest pain clinic. Patients were randomized to best practice usual care, or intervention with development of a proactive cardiovascular risk management strategy framed around a discussion of the individual's absolute risk. Patients found to have a cardiac cause of symptoms were excluded as they constitute a secondary prevention population. Primary outcome was 5-year absolute cardiovascular risk score at minimum 12 months follow up. Secondary outcomes were individual modifiable risk factors (lipid profile, blood pressure, smoking status).
Results
192 people entered the study; 100 in the intervention arm and 92 in usual care. There was no statistical difference between the two groups' baseline sociodemographic and clinical variables. The intervention group showed greater reduction in 5-year absolute risk scores (difference −2.77; p<0.001), and more favourable individual risk factors, although only smoking status and LDL cholesterol reached statistical significance (table).
Conclusion
An absolute risk-guided proactive risk factor management strategy employed opportunistically in a chest pain clinic significantly improves 5-year cardiovascular risk scores.
