Cardiac rehabilitation reduces two-year mortality after coronary artery bypass grafting.
This study analyzed the outcome of cardiac rehabilitation (CR) use for patients who have undergone coronary revascularization procedures. The study looked at Medicare fee-for-service claims linked to surgical data patients discharged alive following isolated coronary artery bypass grafting (CABG) from January 2015 to October 2019. A total of 3,848/6,412 (60.0%) of patients were enrolled in CR for an average of 23.2 sessions with 770/6,412 (12.0%) completing all recommended 36 sessions. Predictors of post-discharge CR use included increasing age, discharge to home (vs extended care facility), and shorter length of stay. Unadjusted and inverse probability treatment weighting (IPTW) analyses showed significant reduction in 2-year mortality in CR users as compared to CR non-users (unadjusted 9.4%).

Traditional Chinese medicine for acute myocardial infarction in western medicine hospitals in China.
This study examined the use of traditional Chinese medicine (TCM) in patients admitted for acute myocardial infarction (AMI) in China during the first 24 hours of hospitalization. The data came from the China Patient-centered Evaluative Assessment of Cardiac Events Retrospective Study of Acute Myocardial Infarction. A chart review was done of randomly sampled patients in 2001, 2006 and 2011 in 162 Western medicine hospitals across China. Nearly all (99%) hospitals used some form of TCM, with Salvia miltiorrhiza being the most commonly prescribed. This TCM treatment (and others) was used intravenously and use has increased over the span of the study, despite lack of evidence of benefit or harm.

Association of cardiac rehabilitation with decreased hospitalizations and mortality after ventricular assist device implantation.
This study examined whether outcomes of cardiac patients who had received ventricular assist device (VAD) implementation had decreased hospitalization and mortality with cardiac rehabilitation (CR). Medicare beneficiaries enrolled for disability or aged 65 years and older in 2014 were included. The investigators identified VAD recipients by diagnosis codes. It was found that each 5-year increase in age was associated with attending an additional 1.6 CR sessions and there was a 23% lower 1-year hospitalization risk and a 47% lower 1-year mortality risk.

Association between Medicare expenditure growth and mortality rates in patients with acute myocardial infarction: a comparison from 1999 through 2014.
This study assessed whether components of growth in Medicare expenditures are associated with mortality rates between January 1, 1999, and June 30, 2014, for beneficiaries hospitalized for acute myocardial infarction. It found that the growth in early percutaneous coronary intervention exhibited a negative association with 180-day case fatality. Spending on cardiac procedures was positively associated with 180-day mortality.

Racial and ethnic differences in heart failure readmissions and mortality in a large municipal healthcare system.
This study sought to determine whether racial and ethnic differences exist among patients with similar access to care. It examined outcomes after heart failure hospitalization within a large municipal health system and determined that racial and ethnic differences in outcomes were present.

In-hospital measurement of left ventricular ejection fraction and one-year outcomes in acute coronary syndromes: results from the IMMEDIATE Trial.
The relationships between reduced left ventricular ejection fraction (LVEF) measured during index acute coronary syndrome (ACS) hospitalization and mortality and heart failure (HF) within 1 year are not well-defined. The researchers performed a retrospective analysis of 445 patients who had LVEF measured by left ventriculography or echocardiogram during hospitalization. They found that among patients with ACS, lower in-hospital LVEF is associated with increased 1-year mortality or hospitalization for HF.
