Prevalence and predictors of elevated high-sensitivity C-reactive protein in post-myocardial infarction patients: Insights from the VIRGO and TRIUMPH registries.

ABSTRACT: Elevated high-sensitivity C-reactive protein (hs-CRP) is associated with worse cardiovascular outcomes in patients with acute myocardial infarction (AMI), but little is known about the distribution of hs-CRP levels and predictors of elevated hs-CRP after AMI in the real world. Translational Research Investigating Underlying Disparities in Acute Myocardial Infarction Patients' Health Status (TRIUMPH) and Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients (VIRGO) are prospective AMI registries in the United States that assessed hs-CRP levels 30 days after AMI. TRIUMPH additionally assessed hs-CRP levels at the time of AMI and at 6 months. Hierarchical models were built to examine predictors of elevated hs-CRP (?2.0 mg/L) at 30 days in both registries and at 6 months after AMI in TRIUMPH. Of 3410 patients in both registries, 58.6% had elevated hs-CRP 30 days after AMI. Patients with elevated hs-CRP at 30 days were more likely to be older, female, obese, smokers, report financial difficulties, and have higher low-density lipoprotein cholesterol levels on admission, diabetes, and hypertension. In TRIUMPH, baseline hs-CRP ?2 mg/L (n = 1301) was significantly associated with elevated hs-CRP at follow-up (P < 0.001). Similar associations were found in TRIUMPH patients with elevated hs-CRP at 6 months. Our study identified a high prevalence and several patient characteristics associated with elevated hs-CRP at 1 and 6 months after discharge. Further studies to test routine screening after AMI may be warranted to identify higher-risk patients for more aggressive secondary prevention.

Project description:BackgroundMany clinical investigations depend on participant self-report as a principal method of identifying health care events. If self-report is used as the trigger to collect and adjudicate medical records, any event that is not reported by the patient will be missed by the investigators, reducing the power of the study and misrepresenting the risk of its participants. We sought to determine the rates and predictors of underreporting hospitalization events during the follow-up period of a prospective study of patients hospitalized with an acute myocardial infarction.Methods and resultsThe TRIUMPH (Translational Research Investigating Underlying Disparities in Acute Myocardial Infarction Patients' Health Status) registry, a longitudinal multicenter cohort study of people with acute myocardial infarction in the United States, queried patients for hospitalization events during interviews at 1, 6, and 12 months. To validate these self-reports, medical records for all events at every hospital where the patient reported receiving care were acquired for adjudication, not just those for the reported events. Of the 4340 participants in TRIUMPH, 1209 (28%) reported at least one hospitalization. After medical records abstraction and adjudication, we identified 1086 hospitalizations from 639 participants (60.2±12 years of age, 38.2% women). Of these hospitalizations, 346 (31.9%) were underreported by the participants. Rates of underreporting ranged from 22.5% to 55.6% based on different patient characteristics. The odds of underreporting were highest for those not currently working (adjusted odds ratio, 1.66 [95% CI, 1.04-2.63]), lowest for those married (adjusted odds ratio, 0.50 [95% CI, 0.33-0.76]), and increased the longer the elapsed time between the admission and the patient's follow-up interview (adjusted odds ratio per month, 1.16 [95% CI, 1.08-1.24]). There was a substantial within-individual variation on the accuracy of reporting.ConclusionsHospitalizations after acute myocardial infarction are commonly underreported in interviews and should not be used alone to determine event rates in clinical studies.
