Underutilization of Coronary Artery Disease Testing Among Patients Hospitalized With New-Onset Heart Failure.

ABSTRACT:

Background

Although ischemic coronary artery disease (CAD) is the most common etiology of heart failure (HF), the extent to which patients with new-onset HF actually undergo an ischemic work-up and/or revascularization is not well defined.

Objectives

This study sought to analyze the patterns of testing for ischemic CAD and revascularization in patients with new-onset HF.

Methods

This was a retrospective cohort study using Truven Health MarketScan Commercial and Medicare databases from 2010 to 2013. The occurrence of noninvasive and invasive ischemic CAD testing and revascularization procedures were examined among patients with new inpatient HF diagnoses during the index hospitalization and within 90 days of admission.

Results

Among 67,161 patients identified with new-onset HF during an inpatient hospitalization, only 17.5% underwent testing for ischemic CAD during the index hospitalization, increasing to 27.4% at 90 days. Among patients with new-onset HF, only 2.1% underwent revascularization during the index hospitalization for HF; by 90 days, the revascularization rate had increased to 4.3%. Of the tests performed for ischemic CAD, stress testing (nuclear stress testing or stress echocardiography) was performed in 7.9% of new-onset HF patients during the index hospitalization (14.6% within 90 days), whereas coronary angiography was performed in 11.1% of patients during the index hospitalization (16.5% within 90 days). In adjusted analyses, HF patients carrying a baseline diagnosis of CAD had greater odds of noninvasive ischemic testing (odds ratio: 1.25; 95% confidence interval: 1.17 to 1.33; p < 0.0001), as well as invasive ischemic testing (odds ratio: 1.93; 95% confidence interval: 1.83 to 2.05; p < 0.0001), at the index hospitalization than those without baseline CAD.

Conclusions

The majority of patients hospitalized for new-onset HF did not receive testing for ischemic CAD either during hospitalization or within 90 days, which suggests significant underutilization of ischemic CAD assessment in new-onset HF patients.

Project description:AimsCoronary artery disease (CAD) is a common cause of heart failure (HF). It remains unclear who, when and why to direct towards coronary revascularization. The outcomes of coronary revascularization in HF patients are still a matter of debate nowadays. This study aims to evaluate the effect of revascularization strategy on all-cause of death in the context of ischaemic HF.Methods and resultsAn observational cohort was conducted on 692 consecutive patients who underwent coronary angiography at the University Hospital of Toulouse between January 2018 and December 2021 for either a recent diagnosis of HF or a decompensated chronic HF, and in whom coronary angiograms showed at least 50% obstructive coronary lesion. The study population was divided into two groups according to the performance or not of a coronary revascularization procedure. The living status (alive or dead) of each of the study's participants was observed by April 2022. Seventy-three per cent of the study population underwent coronary revascularization either by percutaneous coronary intervention (66.6%) or coronary artery bypass grafting (6.2%). Baseline characteristics including age, sex and cardiovascular risk factors did not differ between the invasive and conservative groups, respectively. Death occurred in 162 study participants resulting in an all-cause mortality rate of 23.5%; 26.7% of observed deaths have occurred in the conservative group versus 22.2% in the invasive group (P = 0.208). No difference in survival outcomes has been observed over a mean follow-up period of 2.5 years (P = 0.140) even after stratification by HF categories (P = 0.132) or revascularization modalities (P = 0.366).ConclusionsFindings from the present study showed comparable all-cause mortality rates between groups. Coronary revascularization does not modify short-term survival outcomes in HF patients compared with optimal medical therapy alone outside the setting of acute coronary syndrome.

Project description:BackgroundMultiple studies have demonstrated strong associations between cardiorespiratory fitness and lower cardiovascular disease mortality. In contrast, little is known about associations of fitness with nonfatal cardiovascular events.Methods and resultsLinking individual participant data from the Cooper Center Longitudinal Study with Medicare claims files, we studied 20642 participants (21% women) with fitness measured at the mean age of 49 years and who survived to receive Medicare coverage from 1999 to 2009. Fitness was categorized into age- and sex-specific quintiles (Q) according to Balke protocol treadmill time with Q1 as low fitness. Fitness was also estimated in metabolic equivalents according to treadmill time. Associations between midlife fitness and hospitalizations for heart failure and acute myocardial infarction after the age of 65 years were assessed by applying a proportional hazards model to the multivariate failure time data. After 133514 person-years of Medicare follow-up, we observed 1051 hospitalizations for heart failure and 832 hospitalizations for acute myocardial infarction. Compared with high fitness (Q4-5), low fitness (Q1) was associated with a higher rate of heart failure hospitalization (14.3% versus 4.2%) and hospitalization for myocardial infarction (9.7% versus 4.5%). After multivariable adjustment for baseline age, blood pressure, diabetes mellitus, body mass index, smoking status, and total cholesterol, a 1 unit greater fitness level in metabolic equivalents achieved in midlife was associated with ≈20% lower risk for heart failure hospitalization after the age of 65 years (men: hazard ratio [95% confidence intervals], 0.79 [0.75-0.83]; P<0.001 and women: 0.81 [0.68-0.96]; P=0.01) but just a 10% lower risk for acute myocardial infarction in men (0.91 [0.87-0.95]; P<0.001) and no association in women (0.97 [0.83-1.13]; P=0.68).ConclusionsFitness in healthy, middle-aged adults is more strongly associated with heart failure hospitalization than acute myocardial infarction outcomes decades later in older age.
