Percutaneous coronary interventions in nonagenarians: in-hospital mortality and outcome at one year follow-up

Prognosis of PCI in AMI setting in the elderly population: Outcomes from the multicenter prospective e-ULTIMASTER registry

BACKGROUND

Elderly patients with ST-elevation myocardial infarction (STEMI) who undergo percutaneous coronary intervention (PCI) are usually excluded from major trials.

HYOPTHESIS

This study sought to assess 1-year clinical outcomes following PCI with a drug-eluting stent in patients older than 80 years old with STEMI.

METHODS

The large all-comer, multicontinental e-ULTIMASTER registry included 7507 patients with STEMI who underwent PCI using the Ultimaster stent. The primary clinical endpoint was 1-year target lesion failure, a composite of cardiac death (CD), target vessel-related myocardial infarction (TV-MI), or clinically driven target lesion revascularization (CD-TLR).

RESULTS

There were 457 (6.1%) patients in the elderly group (≥80 years old) that were compared to 7050 (93.9%) patients <80 years. The elderly patients included more female patients and had significantly more comorbidities and had more complex coronary anatomy. The primary endpoint occurred in 7.2% of the elderly, compared to 3.1% of the younger group (p < .001). All-cause mortality was significantly higher among the elderly group compared to the younger group (10.1% vs. 2.3%, p < .0001), as well as CD (6.1% vs. 1.6%, p < .0001), but not TV-MI (1.1% vs. 0.7%, p = .34) or CD-TLR (1.1% vs. 1.4%, p = .63).

CONCLUSION

Elderly patients with STEMI presentation had a higher incidence of the composite endpoint than younger patients. All-cause and CD were higher for elderly patients compared to patients younger than 80 years old. However, there was no difference in the incidence of TV-MI or target lesion revascularizations. These findings suggest that PCI for STEMI in elderly patients is relatively safe.

[Complications of coronary invasive procedures in nonagenarians: A case-control study]

INTRODUCTION

Coronary heart disease is the leading cause of morbidity and mortality in nonagenarians, whose numbers have doubled in twenty years. In the absence of recommendations, the place of coronary invasive strategy in this population remains a therapeutic challenge and its interest as well as its risks are poorly established. The aim of our study was to evaluate the safety of coronary invasive practice in the nonagenarian population for all indications.

POPULATION AND METHODS

This was a monocentric case-control study conducted from January 1, 2010 to May 30, 2019. The patients included were all nonagenarians who had undergone coronary angiography at the centre hospitalier de Troyes during this period. For each patient included, two controls matched on sex, date of procedure and procedure were drawn at random. The main judgment criterion was the occurrence of immediate per- or post-procedure complications during the stay in which the procedure was performed. The main secondary outcome measures were average length of stay, occurrence of intercurrent events during the stay (nosocomial infections, confusional syndrome), and loss of autonomy.

RESULTS

In all, 59 nonagenarians and 118 controls were included in our study. We identified 30.5% major complications in the nonagenarians versus 10.2% in the controls (P=0.001; OR=0.26 [0.1-0.6]), with a significant difference in the occurrence of cardiogenic shock (P=0.04), heart failure (P=0.02) and ventricular rhythm disorders (P=0.04). Post-procedure acute renal failure was greater in the nonagenarians (P=0.02; OR=0.20 [0.05-1.57]). The mean length of stay was on average twice as long in the nonagenarians.

CONCLUSION

Nonagenarian patients are subject to more complications when undergoing coronary invasive procedures compared to patients under 75.

[Interests and limitations of percutaneous coronary intervention strategy in nonagenarian patients: A single center experience]

AIM

To expose our center results in the angioplasty in nonagenarians and to evaluate its effectiveness but also the MACEs and the mortality in the short and long term.

METHODS

A retrospective study of 98 patients admitted to the Antibes hospital center from November 2013 to September 2018.

RESULTS

The median age was 91.8 [90.8-93.4]. 52.6% was male. 9.7% of the patients had a polyvascular site. 50.6% of patients had moderate renal failure. The radial approach was used in 88.4% of cases. 21.6% of patients had tri-truncal lesions, while 46.4% were monotruncular, LAD artery was the culprit artery in 67% of cases. One stent per lesion was used in the majority of cases. Our successful rate was 90%. After angioplasty, 96% of the patients underwent double antiaggregation platelet therapy, 74.4% under clopidogrel. The presence of arrhythmias before angioplasty, the femoral approach, the coronary dissection and cardiogenic shock after angioplasty were predictors of short- and long-term mortality. Diabetes, history of myocardial infarction, impaired left ventricular ejection fraction, calcified coronary lesions, occurrence of arrhythmias or signs of heart failure on post-procedure were predictors of MACE occurrence.

CONCLUSIONS

This study demonstrates that angioplasty in selected population of nonagenarians is perfectly feasible with a good risk/benefit ratio and specifies the different predictors of MACE, both short- and long-term mortality.

Prognosis of primary percutaneous coronary intervention in elderly patients with ST-elevation myocardial infarction

Objective

To evaluate the prognosis of primary percutaneous coronary intervention (PPCI) and medical therapy (MT) in elderly patients presenting with ST-elevation myocardial infarction (STEMI).

Methods

A total of 238 STEMI patients aged above 80 and treated with PPCI (n = 186) and MT (n = 52) at Harefield Hospital, London were included in this study. Patients who did not have true STEMI based on non-diagnostic electrocardiogram (ECG) for STEMI and negative troponin, who presented with left bundle branch block (LBBB) and had normal coronaries were excluded from this study. Primary PCI was defined as any use of a guidewire for more than diagnostic purposes in patients with STEMI, whereas conventional MT was defined as treatment of patients with anti-platelets and anti-thrombotic medications without thrombolysis.

Results

The survival rate of PPCI patients was 86% (n = 160) at month 1 followed by 83.9% (n = 156) at month 6, and 81.2% (n = 151) at month 12. The survival rate of MT patients was 44.2% (n = 23) at month 1 followed by 36.5% (n = 19) at month 6, and 34.6% (n = 18) at month 12. Compared to MT, significantly fewer comorbidities were found in the PPCI group. Ventricular fibrillation (VF) (4.8%) and consequent admission to intensive care unit (7%) were the major complications of the PPCI group.

Conclusion

PPCI has a higher survival rate and, compared to MT, fewer comorbidities were observed in the PPCI group of elderly patients presenting with STEMI.

Correlation between comprehensive evaluation of coronary artery lesion severity and long-term clinical outcomes in Chinese octogenarians with acute coronary syndrome

BACKGROUND

There is little known about long-term outcome data regarding acute coronary syndrome (ACS) in Chinese octogenarians (> 80 years old). Long-term outcomes of octogenarians with ACS may be associated with increased complicated coronary artery lesion severity.

METHODS

We classified 536 consecutive octogenarians with ACS into four groups based on Gensini score. Survival and major adverse cardiac event (MACE) rates were calculated using the Kaplan-Meier method. Multivariate Cox regression was used to identify mortality predictors. The follow-up period was 27 (IQR15-36) months.

RESULTS

The overall long-term mortality rate was 9.1% and increased from 3.0% in group 1 to 16.7% in group 4. Increasing coronary artery lesion severity was associated with increased long-term mortality and MACE rates. ROC curve analysis showed that the predictive cut-off value of Gensini score for mortality was 53. Gensini score provided significant reclassification of mortality (net reclassification index 0.195, P<0.01). Age, gender, heart rate, SBP, chronic renal failure, e-GFR, GRACE score, Gensini score, and ACS type were different between surviving and deceased patients. Notably, chronic renal failure (OR=2.55, P=0.036), GRACE score (OR=1.10, P=0.006), and Gensini score(OR=1.11, P=0.003) were the independent predictors of long-term mortality.

CONCLUSIONS

Long-term mortality of octogenarians with ACS was associated with increased comprehensive coronary artery lesion severity. Gensini score was an effective parameter for evaluation of long-term mortality.

[Use and limitations of invasive coronary strategy in nonagerians]

BACKGROUND

Nonagenarians are systematically excluded from studies of interventional cardiology. Few data exist on the usefulness, safety, and results of coronary angiography (CA) and percutaneous coronary intervention (PCI) in this population.

PURPOSE

To evaluate the benefits and hazards of CA and PCI in nonagenarians.

METHODS

Retrospective study conducted from the database (Cardioreport(®)) of the CH de Versailles, from January 2001 to December 2011.

RESULTS

From the 15,806 procedures performed in the center during the period, 107 (0.9%) were done in 97 patients aged ≥90years. Half of them underwent PCI. Median age was 92±2years (range: 90 to 100), 56% were women. Main indication was an acute coronary syndrome (77%, acute STEMI in 39%). The first group (n=58) had a single CA leading to strengthen medical treatment, and CABG in one case. The second group (n=49) had a CA followed by immediate (41) or delayed (8) PCI. The primary success rate of PCI was 90%. Radial route was used in 94% in the period 2009-2011 (51% overall). Failure of arterial access (4%) and difficulties of catheterization (13%) were rare. Severe complications occurred in 19%. They were local (11 hematomas, 6 severe, 4 transfusions, and 1 fatal acute ischemia of a lower limb), and general (1 stroke, 1 death by left main rupture during PCI). Twenty percent of the complications (11% of severe ones) were directly related to the procedure. Overall hospital mortality was 10%.

CONCLUSIONS

Angiography is feasible in nonagenarians by radial approach without failures and with a reduced rate of complications. PCI was indicated in about half of the cases. PCI may be proposed in nonagerians with a high success rate, and an acceptable risk of local and general complications.

Percutaneous coronary intervention in nonagenarians: pros and cons

Percutaneous coronary intervention is a mainstay in the management of symptomatic or high-risk coronary artery disease. The bulk of clinical evidence and experience underlying this fact relies, however, on relatively young patients. Indeed, few data of very limited quality are available which adequately define the risk-benefit and cost-benefit profile of coronary angioplasty and stenting in very old subjects, such as those of 90 years of age or older (i.e., nonagenarians). The aim of this review is to provide a concise, yet practical, synthesis of the available evidence on percutaneous coronary revascularization in the very elderly. The main arguments elaborated upon are to what extent we can extrapolate findings from studies including younger patients to nonagenarians, whether we should provide higher priority to prognosis or quality of life in such patients, and whether we can afford to allocate vast resources to care for such subjects in an era of financial constraints. Our review of 18 studies and 1082 patients suggest that percutaneous coronary intervention is feasible and associated with acceptable short- and long-term results in this population, which is nonetheless fraught with a high mortality risk irrespective of the revascularization procedure. Accordingly, the pros and cons of percutaneous coronary intervention should be carefully weighed when considering this treatment in nonagenarians.

Safety, effectiveness, and outcomes of cardiac catheterization in nonagenarians

With an aging population, nonagenarians (≥90 years of age) are increasingly being considered for cardiac catheterization. Because of the paucity of outcomes data in this population, we sought to evaluate the acute and intermediate outcomes of nonagenarians undergoing cardiac catheterization. A retrospective cohort of 44 nonagenarians undergoing 53 cardiac catheterizations from 2002 to 2010 was identified. Mean age was 91 years (range 90 to 96) with 57% of patients being women. Thirteen percent presented with ST-segment elevation myocardial infarction, 32% with non-ST-segment elevation myocardial infarction, 14% with unstable angina, 25% with chronic angina, and 16% with aortic stenosis. Eighteen percent had left main coronary artery disease and 73% had multivessel coronary disease. Complications occurred in 6 of 44 patients (3 with acute kidney injury, 2 with atrial fibrillation, 1 with femoral artery pseudoaneurysm). Twenty patients were treated with medical management, 1 patient underwent coronary artery bypass surgery, and 2 patients underwent aortic valve replacement. Twenty-one patients underwent percutaneous coronary intervention in 27 different vessels. There was procedural success in 93% of these patients. There were no major adverse cardiac events. Five complications occurred after the intervention (4 atrial fibrillations, 1 femoral artery pseudoaneurysm). Cumulative mortalities at 1 month and 6 and 12 months were 0%, 9%, and 20% respectively. In patients who underwent percutaneous coronary intervention or surgery, mortalities were 0%, 0%, and 13% at 1 month and 6 and 12 months, respectively.

Outcome of contemporary percutaneous coronary intervention in the elderly and the very elderly: insights from the Blue Cross Blue Shield of Michigan Cardiovascular Consortium

BACKGROUND

There is a paucity of data on the outcome of contemporary percutaneous coronary intervention (PCI) in the elderly. Accordingly, we assessed the impact of age on outcome of a large cohort of patients undergoing PCI in a regional collaborative registry.

HYPOTHESIS

Increasing age is associated with a higher incidence of procedural-related complications.

METHODS

We evaluated the outcome of 152,373 patients who underwent PCI from 2003 to 2008 in the 31 hospitals participating in the Blue Cross Blue Shield of Michigan Cardiovascular Consortium. The procedural outcomes of the cohort were compared by dividing patients into < 70 years of age, 70 to 79 years, 80 to 84 years, 85 to 89 years, and ≥ 90 years.

RESULTS

Of the cohort, 64.64% were <70 years of age, 23.83% were 70 to 79 years, 7.85% were 80 to 84 years, 3.09% were 85 to 89 years, and 0.58% were 90 years or older. Increasing age was associated with an increase in all-cause in-hospital mortality, contrast-induced nephropathy, transfusion, stroke/transient ischemic attack, and vascular complications. The overall in-hospital mortality rate was 1.09% and increased from 0.67% in those younger than 70 years up to 5.44% in those 90 years old or greater. The mortality rate in patients over 80 years approached 12% to 15% for those with ST-segment myocardial infarction and 39% in cardiogenic shock patients.

CONCLUSIONS

The proportion of elderly patients referred for PCI is increasing. Procedural complications increase with age, and patients presenting with unstable symptoms are at the highest risk.

Predictors of the early outcome in elderly patients with ST elevation myocardial infarction treated with primary angioplasty: a single center experience

Elderly patients are under-represented in trials assessing strategies of early coronary revascularization in acute myocardial infarction, though they are the fastest growing segment of our population. The aims of the present investigation, performed in 357 elderly (≥75 years) patients with ST elevation myocardial infarction (STEMI) submitted to primary percutaneous coronary intervention (PCI) consecutively admitted to our Intensive Cardiac Care Unit (ICCU) from 1 January 2006 to 31 December 2009, were as follows: (a) to identify predictors for in-ICCU mortality among clinical, angiographic and metabolic factors and (b) to evaluate whether there are gender-related differences in management, outcome and in the metabolic and inflammatory responses to acute myocardial ischemia. At multivariable backward stepwise logistic regression analysis, the following variables were independent predictors for in-ICCU mortality in the overall population: age (OR 1.15; 95% CI 1.05-1.27; p < 0.003), admission glycemia (OR 2.24; 95% CI 1.41-3.56; p < 0.001), left ventricular ejection fraction (LVEF) (OR 0.92; 95% CI 0.88-0.97; p < 0.001), primary PCI failure (OR 4.70; 95% CI 1.70-12.98; p < 0.003). In elderly STEMI patients submitted to primary PCI, early mortality can be related to age, hemodynamic derangement (as indicated by LVEF), the rate of procedural success, and increased glucose values. No gender-related differences in management were detectable in our series. Our data strongly suggest that, in elderly patients in the acute phase of STEMI, since hyperglycemia is a modifying factor, glucose values deserve a more intensive treatment. Further studies, performed specifically in elderly STEMI patients, should be addressed to identify the glucose cut-off values able to influence the outcome.
