Background: One month following a myocardial infarction (MI), more than a third of older adults (age ≥65 years) are frail as demonstrated by slow gait speed (≤ 0.65 m/sec). The prognostic significance of frailty in a cardiovascular population in terms of future health states is unknown. Methods: The TRIUMPH longitudinal registry enrolled 1314 older adults (age ≥65 years) following an acute MI from 24 US centers. Gait speed (m/sec) was determined at one month (to allow for acute recovery) in 329 patients with in-home follow up. Using averages of 3 timed walks over 15-feet, patients were stratified by gait speed into 2 groups: slow (<0.65m/sec) and preserved (≥0.65m/sec). One year basic (mobility, self care) and instrumental activities of daily living (ADL) (phone, meds, travel, money), physical function score (SF12 PCS), quality of life (Seattle Angina Questionnaire (SAQ)), and mortality were assessed. Results: Slow gait speed was present in 38% (N=126) of older adults at 1 month. At 1 year, despite similar survival, frail adults were much more likely to need help with basic and instrumental (ADL), and had lower physical function and quality of life (QOL) compared to non-frail adults. ( table ) Slower gait speed remained a significant predictor of worse physical function at 1 year after adjustment for baseline physical function (p=0.013). Conclusions: Frailty is common in older adults following an MI, and those with frailty are at substantial risk for continued impairment over time. Understanding the mechanisms or reversibility of this vulnerable state would contribute to optimization of independence and quality of life among older adults with cardiovascular disease.

Background— Communicating prognosis to enable shared decision-making is strongly endorsed by heart failure (HF) guidelines. Patients are concerned with both their quantity and quality of life (QoL). To facilitate the recognition of patients at high risk for unfavorable future QoL or death, we created a simple prognostic tool to estimate this combined outcome. Methods and Results— We identified factors associated with 6-month mortality or persistently unfavorable QoL, defined by Kansas City Cardiomyopathy Questionnaire (KCCQ) scores <45 at 1 and 24 weeks after hospital discharge, among 1458 patients from the Efficacy of Vasopressin Antagonism in HF Outcome Study with Tolvaptan (EVEREST). Within 24 weeks of discharge, 478 (32.8%) patients had died and 192 (13.2%) patients had serial KCCQ scores <45. After adjusting for 23 predischarge covariates, independent predictors of the combined end point included low admission KCCQ score, high B-type natriuretic peptide, hyponatremia, tachycardia, hypotension, absence of β-blocker therapy, and history of diabetes mellitus and arrhythmia. A simplified predischarge HF score for subsequent death or unfavorable QoL had moderate discrimination ( c -statistic 0.72). Predischarge clinical covariates were substantially different in predicting the QoL end point as compared with traditional death or rehospitalization end points. Conclusions— At the time of hospital discharge, readily available clinical characteristics are associated with HF patients at high risk for persistently unfavorable QoL or death over the next 6 months. Such information can target patients for whom aggressive treatment options (eg, devices or transplantation) and/or end-of-life discussions should be strongly considered before hospital discharge.

Abstract Aims Hospitalized heart failure (HF) patients are at high risk for death and readmission. We examined the incremental value of data obtained 1 week after HF hospital discharge in predicting mortality and readmission. Methods and results In the Efficacy of Vasopressin Antagonism in Heart Failure Outcome Study with tolvaptan, 1528 hospitalized patients (ejection fraction ≤40%) with a physical examination, laboratories, and health status [Kansas City Cardiomyopathy Questionnaire (KCCQ)] assessments 1 week after discharge were included. The ability to predict 1 year cardiovascular rehospitalization and mortality was assessed with Cox models, c-statistics, and the integrated discrimination improvement (IDI). Not using a beta-blocker, rales, pedal oedema, hyponatraemia, lower creatinine clearance, higher brain natriuretic peptide, and worse health status were independent risk factors for rehospitalization and death. The c-statistic for the base model (history and medications) was 0.657. The model improved with physical examination, laboratory, and KCCQ results, with IDI increases of 4.9, 7.0, and 3.2%, respectively (P &lt; 0.001 each). The combination of all three offered the greatest incremental gain (c-statistic 0.749; IDI increase 10.8%). Conclusion Physical examination, laboratories, and KCCQ assessed 1 week after discharge offer important prognostic information, suggesting that all are critical components of outpatient evaluation after HF hospitalization.
