National Trends in the Incidence, Management, and Outcomes of Heart Failure Complications in Patients Hospitalized for ST-Segment Elevation Myocardial Infarction.

ABSTRACT:

Objective

To analyze contemporary trends in the incidence, management, and clinical outcomes of heart failure (HF) complications in patients hospitalized for ST-segment elevation myocardial infarction (STEMI) in the United States.

Patients and methods

Using the 2003 through 2010 Nationwide Inpatient Sample databases, all patients with STEMI who were 18 years and older with acute HF were identified. Overall trends in the incidence of HF, coronary intervention, and in-hospital mortality were analyzed.

Results

Of 1,990,002 hospitalizations with a primary diagnosis of STEMI, 471,525 (23.7%) had HF complication (decreasing from 25.4% [95% CI, 25.3%-25.6%] in 2003 to 20.7% [95% CI, 20.5%-20.8%]) in 2010 (P trend<.001). The incidence of cardiogenic shock in patients with HF-complicated STEMI increased from 13.9% (95% CI, 13.6%-14.1%) to 22.6% (95% CI, 22.2%-23.0%) during this period (P trend<.001). From 2003 through 2010, the use of diagnostic coronary angiography and percutaneous coronary intervention increased in patients with HF-complicated STEMI from 44.3% to 62.1% and from 25.0% to 48.1%, respectively. In-hospital mortality decreased significantly in patients with HF-complicated STEMI (from 18.1% to 15.1%) and in subgroups of those with (from 42.4% to 29.9%) and without (from 14.1% to 10.8%) cardiogenic shock (all P trend<.001). The adjusted odds ratio (AOR) (per year) of death was 0.992 (95% CI, 0.988-0.997; P<.001), which changed significantly after additional adjustment for coronary intervention (AOR [per year], 1.012; 95% CI, 1.008-1.017; P<.001).

Conclusion

The incidence and in-hospital mortality of HF-complicated STEMI has decreased significantly during recent times along with increased use of percutaneous coronary intervention and diagnostic coronary angiography.

Project description:ImportanceChallenges to improving ST-segment elevation myocardial infarction (STEMI) care are formidable in low- to middle-income countries because of several system-level factors.ObjectiveTo examine access to reperfusion and percutaneous coronary intervention (PCI) during STEMI using a hub-and-spoke model.Design, setting, and participantsThis multicenter, prospective, observational study of a quality improvement program studied 2420 patients 20 years or older with symptoms or signs consistent with STEMI at primary care clinics, small hospitals, and PCI hospitals in the southern state of Tamil Nadu in India. Data were collected from the 4 clusters before implementation of the program (preimplementation data). We required a minimum of 12 weeks for the preimplementation data with the period extending from August 7, 2012, through January 5, 2013. The program was then implemented in a sequential manner across the 4 clusters, and data were collected in the same manner (postimplementation data) from June 12, 2013, through June 24, 2014, for a mean 32-week period.ExposuresCreation of an integrated, regional quality improvement program that linked the 35 spoke health care centers to the 4 large PCI hub hospitals and leveraged recent developments in public health insurance schemes, emergency medical services, and health information technology.Main outcomes and measuresPrimary outcomes focused on the proportion of patients undergoing reperfusion, timely reperfusion, and postfibrinolysis angiography and PCI. Secondary outcomes were in-hospital and 1-year mortality.ResultsA total of 2420 patients with STEMI (2034 men [84.0%] and 386 women [16.0%]; mean [SD] age, 54.7 [12.2] years) (898 in the preimplementation phase and 1522 in the postimplementation phase) were enrolled, with 1053 patients (43.5%) from the spoke health care centers. Missing data were common for systolic blood pressure (213 [8.8%]), heart rate (223 [9.2%]), and anterior MI location (279 [11.5%]). Overall reperfusion use and times to reperfusion were similar (795 [88.5%] vs 1372 [90.1%]; P = .21). Coronary angiography (314 [35.0%] vs 925 [60.8%]; P < .001) and PCI (265 [29.5%] vs 707 [46.5%]; P < .001) were more commonly performed during the postimplementation phase. In-hospital mortality was not different (52 [5.8%] vs 85 [5.6%]; P = .83), but 1-year mortality was lower in the postimplementation phase (134 [17.6%] vs 179 [14.2%]; P = .04), and this difference remained consistent after multivariable adjustment (adjusted odds ratio, 0.76; 95% CI, 0.58-0.98; P = .04).Conclusions and relevanceA hub-and-spoke model in South India improved STEMI care through greater use of PCI and may improve 1-year mortality. This model may serve as an example for developing STEMI systems of care in other low- to middle-income countries.
