Background: Limited data exist regarding the association between marital status and outcomes among octogenarian and nonagenarian patients with heart failure (HF).

Objectives: To examine the association between marital status and outcomes of octogenarian and nonagenarian patients with HF.

Methods: We conducted a retrospective analysis of 1371 octogenarians and nonagenarians who were hospitalized with HF and enrolled in the multicenter national survey in Israel between March and April 2003. The patients were followed until December 2014. Patients were classified into married (n=562) and unmarried (n=809). The clinical characteristics of the patients by marital status categories were compared by using Student's t-test for continuous variables and the chi-square test for categorical variables. Kaplan–Meier survival analysis was used to present survival estimates according to the different marital status categories and the subsequent 4-year survival probability. Multivariate stepwise Cox proportional hazard regression modeling was used to assess the independent predictors of mortality among the study population.

Results: Married patients were more likely to be male, to smoke, and to have past myocardial infarction and previous revascularization. They tended to have higher rates of peripheral vascular disease and dyslipidemia. Survival analysis showed that 4-year mortality rates were similar between married and unmarried patients. The main consistent independent predictors of 4-year mortality were age, advanced HF (New York Heart association (NYHA) > 2), advanced renal failure, low hemoglobin, high Charlson Comorbidity Index, and low admission systolic blood pressure.

Conclusions: Among the octogenarian and nonagenarian population with HF, being unmarried does not confer an increased risk of mortality. Nevertheless, unmarried patients had a different clinical profile. Higher risk profile, co-morbidities, and advanced age impact mortality among octogenarian and nonagenarian patients.

Background: Cardiac surgery is being performed with increasing frequency in patients aged 80 years and older.

Objectives: To examine the long and short-term results of surgery in this age group.

Methods: We retrospectively investigated 202 consecutive patients aged 80 years or older who underwent cardiac surgery between 1991 and 1999. Ninety-six operations (48%) were urgent.

Results: The study group comprised 140 men (69%) and 62 women (31%) with a mean age of 82.1 years (range 80–89). Preoperatively, 120 patients (59%) had unstable angina, 37 (18%) had left main coronary artery disease, 22 (11%) had renal failure, 17 (8.5%) had a history of stroke, and 13 (6.5%) had previous cardiac surgery. Hospital mortality for the whole group was 7.4%. Postoperative complications included: re-exploration for bleeding in 15 (7.4%), stroke in 8 (4%), sternal wound infection in 3 (1.5%), low cardiac output in 17 (8.4%), new Q wave myocardial infarction in 5 (2.5%), renal failure in 17 (8.5%), and atrial fibrillation in 71 (35%). The actuarial survival for patients discharged from the hospital was 66% at 5 years and 46% at 8 years. The type of surgical procedure was significantly associated with increased early mortality (coronary artery bypass grafting only in 2.9%, CABG[1] + valve in 16.1%, valve only in 16.7%; P = 0.01). Significant predictors (P < 0.05) for late mortality included type of surgical procedure, congestive heart failure, and postoperative low cardiac output.

Conclusions: When appropriately applied in selected octogenarians, cardiac surgery can be performed with acceptable mortality and good long-term results.
