Acute and intermediate‐term results of percutaneous coronary stenting in octogenarian patients

Impact of aging on the clinical outcomes of Japanese patients with coronary artery disease after percutaneous coronary intervention

Japan has become an aging society, resulting in an increased prevalence of coronary artery disease. However, clinical outcomes of elderly Japanese patients after percutaneous coronary intervention (PCI) remain unclear. Of the 15,227 patients in the Shinken Database, a single-hospital-based cohort of new patients, 1,214 patients who underwent PCI, was evaluated to determine the differences in clinical outcomes between the elderly (≥75 years) (n = 260) and the non-elderly (<75 years) (n = 954) patients. A major adverse cardiac event (MACE) was defined as a composite end point, including all-cause death, myocardial infarction (MI), and target lesion revascularization. Male gender and obesity were less common, and the estimated glomerular filtration rate (eGFR) was significantly lower in the elderly than in the non-elderly. Left ventricular ejection fraction (LVEF) was comparable between these groups. Left main trunk disease and multivessel disease were more common in the elderly than in the non-elderly group. Occurrence of MACE was frequent, and the incidences of all-cause death, cardiac death, and the admission rate for heart failure were significantly higher in the elderly patients. Multivariate analysis showed that prior MI, low eGFR, and poor LVEF were independent predictors for all-cause death in the elderly patients. Elderly patients had worse clinical outcomes than the non-elderly patients. Low eGFR and LVEF were independent predictors of all-cause death after PCI, suggesting that left ventricular dysfunction and renal dysfunction might synergistically contribute to the adverse clinical outcomes of the elderly patients undergoing PCI.

Cardiac catheterisation in nonagenarians: Single center experience

OBJECTIVE

To explore the treatment, procedure related risks, and outcomes of patients older than 90 years of age undergoing cardiac catheterization.

METHODS

We retrospectively studied 32 patients ≥ 90 years (93.0 ± 1.2 years) who underwent cardiac catheterisation in a tertiary specialist hospital (0.2% of 14,892 procedures during three years). The results were compared to a patient cohort younger than 90 years of age.

RESULTS

Baseline characteristics revealed a higher prevalence of diabetes (P < 0.001), chronic obstructive pulmonary disease (P < 0.04), previous myocardial infarction (P < 0.02), and complex coronary anatomy (SYNTAX score 33 vs. 19) in nonagenarians. Patients < 90 years of age showed more hyperlipidemia (P < 0.01) and previous percutaneous coronary interventions (P < 0.015). Nonagenarians underwent coronary angiography more often for acute coronary syndrome (ACS) (P < 0.003), were presented more often in cardiogenic shock (P < 0.003), and were transferred faster to coronary angiography in cases of ACS (P < 0.0001). The observed in-hospital mortality rate (13% study group vs. 1% control group; P < 0.003) in nonagenarians was lower than the calculated rate of thrombolysis in myocardial infarction (TIMI) and global registry of acute cardiac events (GRACE) mortality and strongly influenced by the severity of clinical presentation and the presence of co-morbidities.

CONCLUSION

Despite the common scepticism that cardiac catheterisation exposes patients ≥ 90 years to an unwarranted risk, our data demonstrate an acceptable incidence of complications and mortality in this group of patients.

Procedural and long-term outcome of primary percutaneous coronary intervention in octogenarians

Background/objectives. To investigate the procedural and long-term outcome of primary percutaneous coronary intervention (PCI) in octogenarians with an acute myocardial infarction.Methods. We performed a retrospective analysis of all consecutive octogenarian patients (n=98) with an acute myocardial infarction treated with primary PCI in the Catharina Hospital in the year 2006. We compared procedural results and outcome with a matched control group composed of non-octogenarians undergoing primary PCI. Follow-up period was one year.Results. The initial success rate of PCI was similar in the two groups but short-term mortality was higher among the elderly patients: 30-day mortality 26.3 vs. 9.6%. Age-adjusted mortality between 30 days and one year was comparable in the two groups and similar to natural survival in the Netherlands. Octogenarians were less likely to have a normal left ventricular function during follow-up (48.3 vs. 66.7%). New York Heart Association (NYHA) class and recurrence rate of myocardial infarction was higher among octogenarians.Conclusion. Technical success rate during primary PCI was as good for octogenarians as in younger patients, but 30-day mortality, though acceptable, was higher among the elderly. After 30 days, age-adjusted mortality was comparable in both groups. (Neth Heart J 2010;18:129-34.).

Comparison of five-year outcome of octogenarians undergoing percutaneous coronary intervention with drug-eluting versus bare-metal stents (from the RESEARCH and T-SEARCH Registries)

Although octogenarians are increasingly referred for percutaneous coronary intervention (PCI), data are lacking on long-term safety and efficacy of drug-eluting stents in this high-risk subpopulation. The aim of this study was to evaluate 5-year clinical outcome of octogenarians who underwent PCI using sirolimus-eluting stents (SESs) or paclitaxel-eluting stents (PESs) compared to bare-metal stents (BMSs). From January 2000 to December 2005, 319 consecutive octogenarian patients who underwent PCI with BMSs (n = 93, January 2000 to April 2002), SESs (n = 52, April 2002 to February 2003), or PESs (n = 174, February 2003 to December 2005) were included prospectively. Primary study end points were all-cause mortality and major adverse cardiac events (MACEs), defined as all-cause death, any myocardial infarction, or any revascularization. Mean age of the study population was 83 ± 2 years and 51% of patients were men. Median follow-up duration was 5.4 years (range 3 to 9). Five-year mortality rates in the BMS, SES, and PES cohorts were similar (41%, 42%, and 41%, respectively). Cumulative 5-year MACE-free survival in the BMS, SES, and PES cohorts were 44%, 52%, and 48%, respectively. Compared to the BMS cohort, adjusted hazard ratios for MACEs in the SES and PES cohorts were 0.5 (95% confidence interval [CI] 0.3 to 0.9, p <0.05) and 0.5 (95% CI 0.2 to 1.4, p = 0.2), respectively. Overall, use of drug-eluting stents was associated with fewer MACEs (adjusted hazard ratio 0.5, 95% CI 0.3 to 0.9, p <0.05) and a trend toward less target vessel revascularization (adjusted hazard ratio 0.5, 95% CI 0.2 to 1.2, p = 0.1). In conclusion, PCI with drug-eluting stents in octogenarians was found to be safe and more effective compared to PCI with BMSs.

Clinical outcome and quality of life of octogenarian patients following percutaneous coronary intervention or surgical coronary revascularization

BACKGROUND

Thus far, the outcome and effect of percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) surgery on the quality of life of octogenarian patients has not been accurately assessed in Japan.

METHODS AND RESULTS

A retrospective analysis of the outcome of invasive coronary revascularization in 130 elderly patients (age, > or =80 years) with ischemic coronary disease was carried out. Their current quality of life was determined by the Seattle Angina Questionnaire. Although the in-hospital death rate was relatively high (21.6% after PCI and 14.3% after CABG surgery), the long-term outcome of the patients who did not die during the in-hospital period after the PCI/CABG surgery was acceptable (5-year survival rate, >60%). All domains of the questionnaire received a favorable score from a majority of the survivors, irrespective of the treatment they received.

CONCLUSIONS

The quality of life and longevity of the octogenarian patients following extensive invasive revascularization for ischemic coronary artery disease were satisfactory.

"Do Least Harm" Philosophy May Suffice for Percutaneous Coronary Intervention in Octogenarians

BACKGROUND

Octogenarians represent one of the most rapidly expanding segments of the population and an ever growing number are undergoing percutaneous coronary intervention (PCI). A simplified approach with incomplete or "culprit-lesion" only PCI may be an option even in multivessel disease, to minimize periprocedural complications while still allowing a meaningful clinical recovery in patients with inherent functional limitations related to age itself. We tried to determine the effects of either complete or partial PCI on procedural and long-term outcome in a consecutive series of octogenarians.

METHODS

In-hospital and 1-year clinical outcomes were collected in elderly patients treated with PCI between January 1998 and March 2004 in our institution.

RESULTS

In a total of 165 octogenarians, 73 elderly patients (44%) underwent complete (COM) and 92 (56%) incomplete (INC) revascularization. Major in-hospital cardiac events were similar in the two subgroups. At 1-year follow-up 65% of patients in the COM and 68% in the INC group (P = ns) referred improvement in angina status and quality of life. Clinically driven repeat PCI was necessary in 16% of COM and 15% of INC patients. Recurrent PCI was mostly required to treat a restenotic index lesion in both groups, while only five patients in the INC group (5.4%) required PCI of a different lesion.

CONCLUSIONS

Current PCI coronary techniques are safe and effective in octogenarians. Restenosis remains the main cause for recurrent events after bare metal stents. Percutaneous revascularization limited to the culprit lesion may suffice in most patients, with favorable clinical outcome at 1 year.

Effectiveness of sirolimus-eluting stent implantation for the treatment of coronary artery disease in octogenarians

Sirolimus-eluting stent (SES) implantation has been shown to reduce repeat revascularization in various randomized trials. The present study evaluated the outcomes after SES implantation in 46 octogenarian patients. SES implantation in octogenarians appears to be feasible and is associated with very small subsequent need for repeat target vessel revascularization at 1 year.
