Abstract
PURPOSE OF REVIEW The rising burden of cardiovascular disease (CVD) in Africa is of great concern. Health data sciences is a rapidly developing field which has the potential to improve health outcomes, especially in low-middle income countries with burdened healthcare systems. We aim to explore the current CVD landscape in Africa, highlighting the importance of health data sciences in the region and identifying potential opportunities for application and growth by leveraging health data sciences to improve CVD outcomes. RECENT FINDINGS While there have been a number of initiatives aimed at developing health data sciences in Africa over the recent decades, the progress and growth are still in their early stages. Its maximum potential can be leveraged through adequate funding, advanced training programs, focused resource allocation, encouraging bidirectional international partnerships, instituting best ethical practices, and prioritizing data science health research in the region. The findings of this review explore the current landscape of CVD and highlight the potential benefits and utility of health data sciences to address CVD challenges in Africa. By understanding and overcoming the barriers associated with health data sciences training, research, and application in the region, focused initiatives can be developed to promote research and development. These efforts will allow policymakers to form informed, evidence-based frameworks for the prevention and management of CVDs, and ultimately result in improved CVD outcomes in the region.

Abstract
Cardiological disorders contribute to a significant portion of the global burden of disease. Cardiology can benefit from Big Data, which are generated and released by different sources and channels, like epidemiological surveys, national registries, electronic clinical records, claims-based databases (epidemiological Big Data), wet-lab, and next-generation sequencing (molecular Big Data), smartphones, smartwatches, and other mobile devices, sensors and wearable technologies, imaging techniques (computational Big Data), non-conventional data streams such as social networks, and web queries (digital Big Data), among others. Big Data is increasingly having a more and more relevant role, being highly ubiquitous and pervasive in contemporary society and paving the way for new, unprecedented perspectives in biomedicine, including cardiology. Big Data can be a real paradigm shift that revolutionizes cardiological practice and clinical research. However, some methodological issues should be properly addressed (like recording and association biases) and some ethical issues should be considered (such as privacy). Therefore, further research in the field is warranted.

One-year clinical outcome and predictors of ischemic and hemorrhagic events after percutaneous coronary intervention in elderly and very elderly patients. Coron Artery Dis 2021; 32:689-697. [PMID: 33587363 DOI: 10.1097/mca.0000000000001028] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/27/2022]
Abstract
BACKGROUND Elderly constitute a high-risk subset of patients but are under-represented in clinical revascularization trials. Our aim was to investigate clinical outcomes and prognosis predictors after percutaneous coronary intervention (PCI) in this population. METHODS Unrestricted consecutive patients with ≥75 years who underwent PCI from 2012 to 2015 were enrolled. The primary ischemic endpoint was the composite of 1-year myocardial infarction, definite/probable stent thrombosis and target vessel revascularization. The primary bleeding endpoint was defined according to the Bleeding Academic Research Consortium (BARC) classification as BARC ≥ 2. RESULTS We enrolled 708 patients (mean age 80 ± 4): 14% were very elderly patients (≥85 years), 27% of patients were diabetic, 23% had chronic kidney disease (CKD), 17% atrial fibrillation and 37% presented acute coronary syndrome. The primary ischemic endpoint was reported in 67 patients (12%): 29 had myocardial infarction (5%), 25 had definite/probable stent thrombosis (4.4%) and 44 had target vessel revascularization (8%). BARC ≥ 2 bleeding was reported in 43 patients (8%). No differences were found in terms of both ischemic and bleeding events between patients with <85 and ≥85 years. Three-vessel disease and use of bare metal stent were independent predictors of the primary ischemic endpoint. Triple antithrombotic therapy and CKD were the only independent predictors of BARC ≥ 2 bleedings. CONCLUSIONS In our experience, elderly patients reported reassuring efficacy and safety outcomes after PCI, even if ischemic and bleeding events were frequent. Three-vessel disease and the use of bare metal stent were the only predictors of primary ischemic endpoint. Triple antithrombotic therapy and CKD were the only predictors of BARC ≥ 2 bleedings.

Abstract
The proportion of the elderly in the total population of the world is growing, and the number of elderly patients with coronary chronic total occlusions (CTO) is huge. The elderly patients often have more extensive coronary artery disease, more severe ischemic burden and higher risk of cardiovascular events, as compared to younger patients, and thereby they might greatly benefit from coronary revascularization, even though they may have higher risk of operative complications. Most interventional cardiologists are more likely to be reluctant to operate complex percutaneous coronary intervention (PCI) in elderly patients. The latest refinements in dedicated CTO-PCI equipment and techniques have led to high rates of success and low complications rates and have made the CTO-PCI procedures safe and effective among the elderly patients. However, up to now, there is no widely recognized consensus or guideline on treatment strategy of elderly CTO patients, and the prognosis in this population is unknown. In this review, we aim to provide an overview of the current evidence and future perspectives on PCI in elderly patients with CTOs.

Outcome after Elective Percutaneous Coronary Intervention Depends on Age in Patients with Stable Coronary Artery Disease - An Analysis of Relative Survival in a Multicenter Cohort and an OCT Substudy. PLoS One 2016; 11:e0154025. [PMID: 27105207 PMCID: PMC4841583 DOI: 10.1371/journal.pone.0154025] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2015] [Accepted: 04/07/2016] [Indexed: 01/26/2023] Open
Abstract
Background Age is a strong predictor of survival in patients with coronary artery disease. In elder patients with increasing co-morbidities percutaneous coronary intervention (PCI) is associated with more complications and worse outcome. The calculation of relative survival rates adjusts for the “background” mortality in the general population by correcting for age and gender. We analyzed if elder patients after elective PCI have a worse relative survival compared to younger patient groups. Methods A total of 8,342 patients who underwent elective PCI at two high volume centers between 1998 and 2009 were analyzed. Results The survival of our patients after PCI (observed survival) was slightly lower compared to the general population (expected survival) resulting in a slightly decreasing relative survival curve. In a multivariate Cox regression model age amongst others was a strong predictor of survival. Stratifying patients according to their age the relative survival curves of younger patients (Quartile 1: <58 years; 2,046 patients), elder patients (Quartile 3: 66–73 years; 2,090 patients) and very old patients (Quartile 4: >73 years; 2,307 patients) were similar. The relative survival of mid-aged patients (Quartile 2: 58–65 years; 1,899 patients) was better than that of all other patient groups. The profile of cardiovascular risk factors differs between the various groups resulting in different composition and burden of coronary plaques in an optical coherence tomography sub-study. Conclusion Patients after elective PCI have a slightly worse long-term survival compared to the age- and sex-matched general population. This is also true for different groups of age except for mid-aged patients between 58 and 63 years. Elder patients between 66 and 73 years and above 73 years have a similar relative survival compared to younger patients below 58 years, and might therefore have similar benefit from elective PCI.

Abstract
BACKGROUND Older adults presenting with acute myocardial infarction (MI) often have multivessel coronary artery disease amenable to percutaneous coronary intervention (PCI), yet the risks of multivessel intervention may outweigh potential benefits in these patients. We sought to determine if nonculprit intervention during the index PCI is associated with better outcomes among older patients with acute MI and multivessel disease. METHODS We examined 19,271 ST-segment elevation MI (STEMI) and 31,361 non-STEMI (NSTEMI) patients 65years or older with multivessel disease in a linked CathPCI Registry-Medicare database, excluding patients with prior coronary artery bypass grafting, left main disease, or cardiogenic shock. Using inverse probability-weighted propensity adjustment, we compared mortality between patients receiving culprit-only vs multivessel intervention during the index PCI procedure. RESULTS Most older MI patients (91% STEMI and 74% NSTEMI) received culprit-only intervention during the index PCI. Among STEMI patients, multivessel intervention during the index PCI was associated with higher 30-day mortality (8.3% vs 6.3%, adjusted hazard ratio [HR] 1.36, 95% CI 1.14-1.62) than culprit-only intervention, and this trend persisted at 1year (13.8% vs 12.2%, adjusted HR 1.14, 95% CI 0.99-1.31). No significant mortality differences were observed among NSTEMI patients at 30days (3.4% vs 4.1%, adjusted HR 1.01, 95% CI 0.88-1.15) or at 1year (10.1% vs 10.8%, adjusted HR 0.99, 95% CI 0.91-1.08). CONCLUSIONS Nonculprit intervention during the index PCI was associated with worse outcomes among STEMI patients, but not NSTEMI patients.

Abstract
INTRODUCTION Cardiovascular diseases contribute to mortality and morbidity in aged individuals. It is crucial to have a clear perception of coronary artery bypass graft (CABG) risks and benefits to make logical decision in aged patients. Unfortunately, cardiovascular disease researches have focused very little on the aged patients. The aim of the present study is to evaluate in-hospital complications in patients older than 70 years old following CABG operation to determine if CABG is preferred or not considering present complications. METHODS In a cross sectional study, 500 patients older than 70 years old were randomly selected (70-75 patients for each year) from March 2004 to March 2011. Descriptive statistical methods were used for evaluating the obtained data. RESULTS Overall, 70.6% of patients (353 individuals) were male and 29.4% were female (147 individuals). Totally, 107 patients (21.4%) had complications during hospitalization; these complications were statistically significant in male individuals. Complications included Stroke 1.6%, deep vein thrombosis 0.8%, MI 2.4%, repeat surgery 2.80%, bleeding 2.40%, and more than 48 hours mechanical ventilation in 13.4%. CONCLUSION Need for more than 48 hours mechanical ventilation and bleeding after surgery were the most occurred complications in these patients.

Abstract
OBJECTIVE To investigate procedural success rates and long-term clinical outcome of percutaneous coronary intervention (PCI) for chronic total occlusions (CTO) in elderly patients. BACKGROUND Little is known about procedural success and long-term clinical outcome of PCI for CTO in the elderly. METHODS A total of 1,791 consecutive patients with 1,852 CTO underwent PCI at three large centers in USA, Italy, and South Korea. Outcomes included procedural success and major adverse cardiac events (MACE, composite of mortality, myocardial infarction, or coronary artery bypass graft surgery [CABG]).Time-to-event analyses were performed using Kaplan-Meier statistics, and the log-rank statistic was used to test for differences between patients aged ≥75 and patients aged <75 years. RESULTS Two hundred and thirteen patients (12%) were aged ≥75 years. Procedural success rates were similar in elderly patients compared with patients <75 years (63.8% vs. 69.1%, P = 0.12). Median follow-up was 890 days (IQR: 380-1,480 days). MACE rates after successful versus failed PCI were 25.8% versus 42.3% in the elderly (P = 0.02) and 11.2 versus 20.8% in younger patients (P < 0.01). In elderly patients, this reduction in MACE after successful PCI was mainly driven by a reduction in CABG (0.0% vs. 20.4%, P < 0.01), there were no significant differences in terms of mortality (19.6% vs. 24.6%, P = 0.13) or MI (11.5% vs. 8.0%, P = 0.87). CONCLUSION CTO PCI in patients ≥75 years has similar success as in patients <75 years. In elderly patients undergoing CTO PCI, MACE rates were relatively high but successful revascularization is associated with a reduction in MACE at 5-year follow-up in both elderly and younger patients.

Abstract
OBJECTIVE With progressive aging, coronary artery disease has been diagnosed at more advanced ages. Although patients aged 65 years or more have been referred to surgical or percutaneous coronary interventions, the best option for coronary artery disease treatment remains uncertain. The current study compared the 3 treatment options for coronary artery disease in patients aged 65 years or more and analyzed the impact of age in treatment options. METHODS Patients were separated according to age: 65 years or more (n = 200) and less than 65 years (n = 411). All patients were followed for 10 years. The rates of overall mortality, acute myocardial infarction, and new revascularizations were analyzed. RESULTS Of 200 patients aged 65 years or more, 68 were randomized to medical therapy, 68 were randomized to percutaneous coronary intervention, and 64 were randomized to coronary artery bypass grafting. At 10 years, overall survival was 63% (medical therapy), 69% (percutaneous coronary intervention), and 66% (coronary artery bypass grafting) (P = .93). The survival free of combined events was 43% (medical therapy), 38% (percutaneous coronary intervention ), and 66% (coronary artery bypass grafting) (P = .007). The survival free of myocardial infarction was 82% (medical therapy), 77% (percutaneous coronary intervention), and 90% (coronary artery bypass grafting) (P = .17), and survival free of new revascularizations was 59% (medical therapy), 58% (percutaneous coronary intervention ), and 91% (coronary artery bypass grafting) (P = .0003). When the 2 age groups were compared, survival free of myocardial infarction for patients treated by percutaneous coronary intervention was 77% (older patients) and 92% (younger patients) (P = .004). CONCLUSIONS In this analysis, treatment options for patients aged 65 years or more who have coronary artery disease yield similar overall survival. However, coronary artery bypass grafting was associated with fewer coronary events, and percutaneous coronary intervention was associated with a higher incidence of myocardial infarction.

Abstract
Ischemic heart disease remains the leading cause of morbidity and mortality in both genders in developed countries. Many women underestimate the effect of coronary artery disease on their health and as a result, the female population tends to be under-investigated for symptoms, with less-aggressive treatment approaches, leading to perceived worse outcomes in this group. Many assumptions about women are from studies where the female population is under-represented and in trials that do not account for gender differences. This article discusses percutaneous coronary intervention in high-risk groups and whether such a gender difference exists.

Abstract
Patients ≥ 80 years old with coronary artery disease constitute a particular risk group in relation to percutaneous coronary intervention (PCI). From 2002 through 2008 we examined the annual proportion of patients ≥ 80 years old undergoing PCI in western Denmark, their indications for PCI, and prognosis. From 2002 through 2009 all elderly patients treated with PCI were identified in a population of 3.0 million based on the Western Denmark Heart Registry. Cox regression analysis was used to compare mortality rates according to clinical indications controlling for potential confounding. In total 3,792 elderly patients (≥ 80 years old) were treated with PCI and the annual proportion increased from 224 (5.4%) in 2002 to 588 (10.2%) in 2009. The clinical indication was stable angina pectoris (SAP) in 30.2%, ST-segment elevation myocardial infarction (STEMI) in 35.0%, UAP/non-STEMI in 29.7%, and "ventricular arrhythmia or congestive heart failure" in 5.1%. Overall 30-day and 1-year mortality rates were 9.2% and 18.1%, respectively. Compared to patients with SAP the adjusted 1-year mortality risk was significantly higher for patients presenting with STEMI (hazard ratio 3.86, 95% confidence interval 3.08 to 4.85), UAP/non-STEMI (hazard ratio 1.95, 95% confidence interval 1.53 to 2.50), and ventricular arrhythmia or congestive heart failure (hazard ratio 2.75, 95% confidence interval 1.92 to 3.92). In patients with SAP target vessel revascularization decreased from 7.1% in 2002 to 2.5% in 2008. In conclusion, the proportion of patients ≥ 80 years old treated with PCI increased significantly over an 8-year period. Patients with SAP had the lowest mortality rates and rates of clinically driven target vessel revascularization decreased over time.

Abstract
AIMS The objective of this study was to evaluate the outcomes and identify the risk factors of in-hospital mortality among elderly patients undergoing PCI in Thailand. METHODS AND RESULTS Included in this study were 4,156 consecutive patients (comprising 639 elderly [age ≥ 75 years] and 3,517 non-elderly [age < 75 years]) undergoing PCI between May 2006 and October 2007. The success rate of PCI was less favourable among elderly compared to the non-elderly patients (91.2% vs. 87.5%; p=0.003). Elderly patients had higher rate of post PCI renal failure (3.9% vs. 1.8%; p=0.001), Q-wave myocardial infarction (3.0 vs. 1.4%, p=0.003), and unadjusted in-hospital mortality (5.3% vs. 2.4%, p ≤ 0.001), compared with non-elderly patients. After adjustment for baseline variables, acute coronary syndrome and heart failure were the two variables most associated with increased mortality (OR=5.95, 95% CI=3.22-11.01), p<0.001 and OR=5.73,95% CI=3.80-8.63), p<0.001, respectively). According to the multivariate analysis, age was not significantly related with increased mortality (OR=1.37, 95% CI=0.87-2.16, p=0.174). CONCLUSIONS Our study highlights the safety and effectiveness of PCI in elderly patients since advanced age is not a predictor of in-hospital mortality.

Abstract
BACKGROUND Despite the high mortality rate in elderly patients with acute myocardial infarction (AMI), the value of coronary angiography (CA) in the elderly has been questioned due to a less favorable outcome. The aim of the study was to determine the prognostic significance of CA on mortality of elderly patients AMI in "real world" practice. METHODS The study cohort comprised 1009 elderly (age > or = 75 years) patients with AMI who were derived from three prospective national surveys between 1996 and 2000 in all 25 CCUs operating in Israel. Baseline characteristics, hospital course, management and outcome of 274 (27%) elderly patients who underwent CA during the index hospitalization were compared with 735 (73%) counterpart patients who did not. RESULTS Patients who underwent CA were on average 2.2 years younger, and were more often with hyperlipidemia (p<0.0001 for each) and with a history of previous percutaneous coronary intervention (p<0.03) than the control group. They had a more favorable clinical presentation: a higher systolic blood pressure (p<0.04), a better Killip class (p<0.03) and an increased frequency of non-Q wave MI (p<0.03). They developed more often recurrent MI (p=0.002) and re-ischemia (p<0.0001). Variables associated with CA use during the index hospitalization were re-infarction, re-ischemia, the year of the index AMI and the availability of an on-site a catheterization laboratory in the hospital, while a higher age and fibrinolytic therapy decreased the likelihood of CA use. Of the patients who underwent CA, 67% underwent coronary revascularization (either PCI and/or CABG). Crude and adjusted mortality rates at 1 year were significantly lower in patients who underwent CA, as compared to counterparts who did not: 21% vs. 37.3%, respectively (p<0.0001), hazard ratio=0.52 (95% confidence interval 0.38-0.71). The benefit of CA was noted in a wide range of subgroups analyzed. CONCLUSIONS In "real world" practice, elderly patients with AMI who undergo CA during hospitalization have a better prognosis at 1 year. Age alone should not be a deterrent to performing CA in elderly patients with AMI. Further large randomized trials are needed to confirm that an invasive approach is beneficial in high-risk elderly patients with AMI. CONDENSED ABSTRACT To determine the prognostic significance of coronary angiography (CA) during the course of acute myocardial infarction (AMI) in "real world" practice on mortality of elderly patients, 1009 such patients were studied. Re-infarction, re-ischemia, the year of the index AMI and the availability of an on-site a Cath. Lab. were variables which increased the likelihood of undergoing CA, while a higher age and fibrinolytic therapy decreased this likelihood. The crude and covariate adjusted mortality rates at 1 year were significantly lower in patients who underwent CA in comparison to counterparts who did not: 21% vs. 37.3%, respectively (p<0.0001), hazard ratio 0.52 (95% confidence interval 0.38-0.71). The benefit of CA was noted across a wide range of subgroups analyzed.

Abstract
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.

Abstract
INTRODUCTION The incidence of ischemic heart disease in the elderly is high. These patients are increasing referred for coronariography. OBJECTIVES Identify factors associated with coronary revascularization in elderly patients. MATERIAL AND METHODS Retrospective study of 473 patients > or = 75 years who underwent coronariography in relationship with ischemic heart disease. Their clinical-epidemiological characteristics and treatment adopted were analyzed. A multivariate analysis model was used to identify factors associated with revascularization. RESULTS Mean age was 77.6 +/- 2.8 years; 70.4% were men. A total of 36% smoked, 53% were hypertensive, 33% diabetics and 30% dislipidemic. Thirty one % had multivessel disease and 11% involvement of left coronary trunk. There was evidence of anterior descending artery in 68%. Medical treatment was done in 48.4%, percutaneous revascularization in 41.5% and surgical in 10.1%. Patients with lesions of the anterior descending artery were revascularized in greater proportion: 67.7% vs 32.3%; p. 0.001. A logistic regression model was used to identify revascularization predictors, obtaining a direct relationship with the involvement of the anterior descending artery (OR: 4.87; 95% CI: 2.98-7.94; (p < 0.001) and inverse on with the previous revascularization (OR: 0.47; 95% CI: 0.26-0.85; p < 0.02), left ventricular dysfunction (OR: 0.58; 95% CI: 0.39-0.88; p = 0.01) and presence of multivessel disease (OR: 0.51; 95% CI: 0.31-0.84; p < 0.01). CONCLUSIONS The elderly subjects with ischemic heart disease who underwent coronariography received revascularizing treatment in somewhat more than 50% of the cases. A direct relationship was found between involvement of the anterior descending artery and performance of revascularizing treatment and an inverse on between previous revascularization, left ventricular dysfunction and presence of multivessel disease.

Abstract
More than 1.2 million percutaneous coronary interventions are performed annually in the United States, with only an estimated 33% performed in women, despite the established benefits of percutaneous coronary intervention and adjunctive pharmacotherapy in reducing fatal and nonfatal ischemic complications in acute myocardial infarction and high-risk acute coronary syndromes. This statement reviews sex-specific data on the safety and efficacy of contemporary interventional therapies in women.

Abstract
BACKGROUND A growing number of patients > or = 80 years require cardiac catheterization. Since little is known about the overall safety of these procedures in this population, we assessed the procedure-related risks and determined predictors for complications. METHODS We studied 1085 consecutive patients > or = 80 years (82.6+/-2.6 years; 526 males, 544 females), who underwent 1384 cardiac catheterizations in a tertiary specialist university hospital (3% of 43,517 procedures). RESULTS A total of 373 patients (35%) required percutaneous coronary interventions (PCI), and 331 (31%) received coronary artery bypass surgery. Thirty-one patients died during hospital stay. Procedure-related complications including vascular injuries occurred in 2.1% after CATH and 11.6% after PCI. CONCLUSIONS Despite the widespread notion that cardiac catheterization exposes patients > or = 80 years to an unwarranted risk, these data demonstrate an acceptable complication rate. Patients #10878;80 years of age should thus not be refused to undergo cardiac catheterization merely based on their age.

Abstract
BACKGROUND Older age has been associated with adverse outcomes in patients undergoing percutaneous coronary intervention (PCI). As PCI technology evolves and the US population becomes proportionally older, assessment of PCI in older age groups is essential. METHODS From the National Heart, Lung, and Blood Institute Dynamic Registry, 4620 PCI-treated patients (1997 to 1999) were studied. Differences in clinical presentation, treatment strategy, and inhospital and 1-year outcomes were compared between patient age groups: younger (<65 years, n = 2537); older (65 to 79 years, n = 1776); and elderly (> or =80 years, n = 307). RESULTS Older and elderly patients had more cardiac and comorbid noncardiac conditions and more extensive and complex arteriosclerosis, including stenoses in bypass grafts. Stent use was similar as age increased (72% vs 73% vs 73%), as was the use of IIb/IIIa receptor antagonists (29% vs 26% vs 28%). Rates of successful treatment of all attempted lesions were 93%, 92%, and 89%, respectively. Adjusted relative risks of inhospital death (1.0 vs 2.91 vs 3.64) and myocardial infarction (1.0 vs 1.35 vs 2.57) increased by age group, as did 1-year mortality rates (1.0 vs 1.87 vs 3.02). However, the relative magnitude of excess mortality rates at 1 year was comparable to that observed by age in the US general population. Age was not associated with 1-year risk of myocardial infarction or coronary artery bypass grafting. CONCLUSIONS Although new technologies may allow for treatment of complex disease in older and elderly patients with comorbid disease, the increased procedural risk remains substantial in these patients. After PCI, the long-term relative risk of death is similar to that expected among persons of similar ages in the general population.

Abstract
Elderly patients are increasingly referred to percutaneous coronary interventions (PCIs). Recent reports suggest complications rates are declining in the elderly. We sought to determine whether procedural and in-hospital outcomes are different in patients aged > or = 75 years undergoing nonemergent PCI as compared to patients age < 75 years. The outcome of 266 consecutive patients age > or = 75 years undergoing nonemergent PCI was compared to that of 1,681 consecutive patients age < 75 years. Compared with younger patients, greater proportions of elderly patients were women and had a history of hypertension, peripheral vascular disease, and cerebral vascular events. Elderly patients had more extensive coronary involvement. Procedural success was similar in both groups (94%). The in-hospital cardiac death rate was significantly higher in the elderly patients (2.3% vs. 0.7%; P = 0.03). Aged patients also had a significantly higher incidence of vascular and bleeding complications. Blood transfusion was required more often in the elderly group (4.5% vs. 2.6%; P = 0.07). The hospitalization length was significantly higher in the elderly group (4.1 +/- 6.0 vs. 2.5 +/- 4.3 day; P = 0.0004). By multivariate logistic regression (adjusted for baseline clinical and angiographic variables), age > or = 75 years was found to be an independent predictor of in-hospital cardiac death (odds ratio = 3.9; 95% CI = 1.3-11.5; P = 0.015). Although PCI is technically successful in patients aged > or = 75 years; it is associated with more acute cardiac and vascular complications and higher in-hospital cardiac mortality.

Abstract
OBJECTIVES We sought to evaluate the results of percutaneous coronary intervention (PCI) in elderly patients in contemporary practice. BACKGROUND Prior studies of PCI in the elderly population demonstrate increased in-hospital mortality, but these studies are limited by small population size. METHODS Using the American College of Cardiology-National Cardiovascular Data Registry (ACC-NCDR) of 100,253 patients, the in-hospital outcomes in all 8,828 PCI procedures performed on octogenarians were evaluated. Patients underwent PCI between 1998 and 2000 at over 145 participating centers. RESULTS The mean age was 83.72 +/- 3.02 years, with female preponderance (53%). The PCI was considered angiographically successful in 93%, stents were placed in 75%, and the post-PCI length of stay was 3.3 +/- 5.1 days. Overall in-hospital mortality was 3.77% but was only 1.35% in PCI without recent myocardial infarction (MI) within one week (p < 0.0001). Patients having PCI within 6 h of the onset of their MI had an increase in mortality tenfold (13.79%) compared with patients without a recent MI (p < 0.0001). All groups that were defined based on time of PCI after MI onset up to seven days had increased mortality (all p < 0.0001). Older age (odds ratio [OR] of 1.03 per incremental year), depressed ejection fraction (EF) (OR 0.69 per 10 points for EF <60%), and time of PCI after MI onset (<6 h, OR 6.87; 6 to 24 h, OR 5.66; 24 h to one week, OR 2.93) were most strongly predictive of outcome by multivariate analysis. The predicted mortality from the multivariate model correlated well with the observed in-hospital mortality up to 20% mortality. A 254-point nomogram was constructed employing the logistic model using a weighted point system. CONCLUSIONS In patients > or = 80 years old, PCI has good success and acceptable mortality. The presence of an acute or recent MI substantially increases the risk of in-hospital death.

Abstract
BACKGROUND Elderly patients with ischemic heart disease are increasingly referred for coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI). However, reports of poor outcomes in the elderly have led to questions about the benefit of these strategies. We studied survival by prescribed treatment (CABG, PCI, or medical therapy) for patients in 3 age categories: <70 years, 70 to 79 years, and > or =80 years of age. METHODS AND RESULTS The Alberta Provincial Project for Outcomes Assessment in Coronary Heart Disease (APPROACH) is a clinical data collection and outcome monitoring initiative capturing all patients undergoing cardiac catheterization and revascularization in the province of Alberta, Canada, since 1995. Characteristics and long-term outcomes of a cohort of >6000 elderly patients with ischemic heart disease were compared with younger patients. In 15 392 patients >70 years of age, 4-year adjusted actuarial survival rates for CABG, PCI, and medical therapy were 95.0%, 93.8%, and 90.5%, respectively. In 5198 patients 70 to 79 years of age, survival rates were 87.3%, 83.9%, and 79.1%, respectively. In 983 patients > or = 80 years of age, survival was 77.4% for CABG, 71.6% for PCI, and 60.3% for medical therapy. Absolute risk differences in comparison to medical therapy for CABG (17.0%) and PCI (11.3%) were greater for patients > or =80 years of age than for younger patients. CONCLUSIONS Elderly patients paradoxically have greater absolute risk reductions associated with surgical or percutaneous revascularization than do younger patients. The combination of these results with a recent randomized trial suggests that the benefits of aggressive revascularization therapies may extend to subsets of patients in older age groups.

Abstract
Procedural success may be lower and complication rates higher after balloon angioplasty in older patients. Elective stent implantation improves procedural outcome in younger patients; however, few series have specifically analyzed the octogenarian population. Therefore, we studied 2,534 consecutive patients (3,965 native coronary artery stenoses) who were treated electively with Palmaz-Schatz stents and divided them into 3 groups: (1) < or = 70 years old (n = 1,805), (2) 71 to 80 years old (elderly, n = 607), and (3) > 80 years old (octogenarian, n = 122). Major in-hospital complications (death, myocardial infarction, and urgent bypass surgery) were significantly higher in the octogenarians than in the elderly and patients < or = 70 years of age (4.5% vs 2.0% and 1.5%; p = 0.001). At 1-year follow-up, cardiac events (death, nonfatal myocardial infarction, and need for any revascularization) did not differ among groups; however, there was a stepwise increase in late death in octogenarians (5%) compared with elderly patients (2%) and patients aged < or = 70 years (1%) (p = 0.001). Target lesion revascularization was similar among the groups (11% in octogenarian vs 14% in elderly and 15% in patients < or = 70 years, p = 0.791). By multivariate logistic regression analysis, age was an independent predictor of late mortality (odds ratio 1.05, p = 0.0001), but not a predictor of target lesion revascularization. Stent implantation in octogenarians is associated with (1) more acute complications, (2) a higher in-hospital mortality, (3) a higher late mortality, and (4) a target lesion revascularization similar to younger patients.

Abstract
Results of 378 consecutive elderly patients (> or = 65 years) undergoing coronary stenting were compared with those of 601 younger patients. Although the restenosis rate was similar in the 2 groups, age > or = 65 years was an independent predictor of in-hospital mortality (relative risk 5.4, 95% confidence interval 1.2 to 20.1) and follow-up mortality (relative risk 2.8, 95% confidence interval 1.3 to 6.1).

Abstract
OBJECTIVES To explore the relation between older age and clinical presentation, procedural success, and in-hospital outcomes among a large unselected population undergoing percutaneous transluminal coronary angioplasty (PTCA). BACKGROUND Although more elderly patients are receiving PTCA, studies of post-PTCA outcomes among the elderly have been limited by small numbers and exclusive selection criteria. METHODS Data were collected as a part of a prospective registry of all percutaneous coronary interventions performed in Maine, New Hampshire, and from 1 institution in Massachusetts between October 1989 and December 1993. Comparisons across 4 age groups, (<60, 60 to 69, 70 to 79, and 80 years and above) were performed using chi-square tests, the Mantel-Haenzsel test for trend, and logistic regression. RESULTS Twelve thousand one hundred seventy-two hospitalizations for PTCA were performed with 507 of them (4%) in persons at least 80 years old. Octogenarians were more likely to be women, have multivessel disease, high-grade stenoses, and complex lesions but were less likely to have hypercholesterolemia, a history of smoking, or have undergone a previous PTCA. In the elderly, PTCAs were more often performed urgently and for unstable syndromes compared with younger age groups. Advancing age is strongly associated with in-hospital death, and among the oldest old with an increased risk of postprocedural myocardial infarction. Despite differing presentation and procedural priority, angiographic success and subsequent bypass surgery did not vary by age. CONCLUSIONS With the increasing age of the population at large as well as that segment at risk for cardiac revascularization, information about age-associated risks of the procedure, especially the substantially higher risk of death in octogenarians, will be critical for both physicians and patients considering PTCA.

Abstract
BACKGROUND Most analyses of complications after percutaneous coronary intervention have been limited to angiographic predictors of abrupt closure. We sought to determine the relation between baseline clinical and angiographic characteristics and clinical ischemic events and whether treatment with the platelet glycoprotein IIb/IIIa receptor antagonist c7E3 reduced ischemic events differentially in patients with distinct lesion morphologic characteristics. In the EPIC trial, a bolus and infusion of c7E3 decreased the 30-day incidence of death, myocardial infarction, and need for revascularization by 35% in 2099 high-risk patients. METHODS We used logistic regression modeling to determine the relations between these patients' baseline clinical and angiographic characteristics and the composite primary end point. We also constructed multivariable models with interaction terms to assess treatment effect on prespecified, core laboratory-assessed, coronary morphologic characteristics. RESULTS The most important predictors of a poor outcome were low weight (chi-square = 10.5, P =.001) and preprocedural percent stenosis (chi-square = 15.0, P <.001). History of hypertension, nonwhite race, and peripheral vascular disease were also associated with an increased risk, as were all measures of lesion complexity except calcification and presence of a side branch. The treatment benefit with abciximab was significantly greater with less complex than with more complex lesion morphologic characteristics. CONCLUSIONS Future risk models should include these baseline characteristics to define the risk for ischemic complications in individual patients, and treatment with abciximab should not be predicated on lesion morphologic findings alone.

Abstract
Coronary artery bypass operations are associated with increased morbidity and mortality in the elderly. Similarly, it has been shown that coronary angioplasty is associated with a higher risk of complications in the elderly than in younger patients. The purpose of this study was to evaluate the 1-month outcome of elderly patients (>75 years old) who were included in the Stenting without Coumadin French Registry. From December 1992 to March 1995, 2,900 patients (mean age 61+/-11 years) were included in this registry. All patients were treated with ticlopidine (250 to 500 mg/day) for 1 month from the day of percutaneous transluminal angioplasty, aspirin (100 to 250 mg/day) for >6 months, and low-molecular-weight heparin (antiXa 0.5 to 1 IU/ml) for 1 month in phase II, 15 days in phase III, and 7 days in phase IV. No heparin was given in phase V. The study group included 233 patients (8.0%) > 75 years old (mean age 79+/-4), 44 (18%) of whom were women. All patients underwent dilatation of a native coronary vessel. One hundred seventeen had unstable angina (50.2%), 20 had postmyocardial infarction ischemia (8.6%), and 6 had acute myocardial infarction (2.6%). Indications for stenting were de novo lesion in 63 patients (27.0%), restenosis in 38 (16.3%), suboptimal result in 48 (20.6%), nonocclusive dissection in 56 (24.0%), and occlusive dissection in 28 (12.0%), respectively. Stented coronary arteries were the left anterior descending in 109 (46.8%), the right in 80 (34.3%), the left circumflex in 40 (17.2%), and the left main in 4 (1.7%). Palmaz-Schatz stents were used in 228 patients (82.0%), AVE microstents in 38 (13.7%), and other stents in 12 (4.3%). More than 1 stent was used in 48 patients (17.3%). The mean diameter of the balloon used for stenting was 3.31+/-0.38 mm and maximal inflation pressure was 12.2+/-2.9 atm. At one-month follow-up, vascular complications occurred in 5 patients, requiring surgery in 2 (1.3%), acute closure occurred in 1 (0.4%), subacute closure in 3 (1.3%), emergency or planned coronary artery bypass graft surgery in none, acute myocardial infarction in 4 (1.7%), stroke in 1 (0.4%), and death in 8 (3.4%). The composite end point of a major cardiac event was observed in 13 cases (5.6%). Coronary stenting using ticlopidine and aspirin appears to be a particularly safe approach in this high-risk subset.

Abstract
We studied 1,238 patients receiving 1,880 coronary stents. In-hospital outcomes were divided by age into <65 years (n = 747, group 1), 65 to 75 years (n = 326, group 2), and >75 years (n = 165, group 3). Procedural success was 97.2%, 95.1%, and 98.8% in groups 1, 2, and 3, respectively (p = NS). There was 1 death (group 1). Myocardial infarction occurred in 1.2%, 2.8%, and 1.8%, bypass surgery occurred in 0.9%, 1.8%, and 1.2%, and repeat balloon angioplasty in 0.3%, 0.6%, and 0% of patients in groups 1, 2, and 3, respectively (p = NS for all comparisons). Vascular complications occurred in 2.8%, 4.9%, and 6.1% in groups 1, 2, and 3, respectively (p <0.05). Six-month follow-up of patients was divided by age: <65 years (n = 564, group 1); 65 to 75 years (n = 221, group 2); and >75 years (n = 122, group 3). Event-free survival was 94.5%, 90.5%, and 89.3% for groups 1, 2, and 3, respectively (p = NS). Death occurred in 0.4%, 0.5%, and 1.6%; myocardial infarction occurred in 1.2%, 2.3%, and 1.6%, and target vessel revascularization in 4.3%, 8.6%, and 7.4% for groups 1, 2, and 3, respectively (p = NS for all comparisons). Thus, coronary stenting produced favorable in-hospital and 6-month outcomes in all 3 age groups. Age itself should not preclude patients from undergoing coronary stenting.

Abstract
OBJECTIVES We sought to compare the short- and long-term mortality rates in patients > or = 70 years old with unstable angina undergoing percutaneous transluminal coronary angioplasty (PTCA) with predicted coronary artery bypass graft surgery (CABG) short-term and U.S. census long-term mortality rates. BACKGROUND Coronary angioplasty is an alternative revascularization strategy for patients with medically refractory rest angina and a high risk of adverse outcomes with CABG. Patients > or = 70 years old are a specific high risk subset. METHODS A total of 131 consecutive patients aged > or = 70 years with unstable angina underwent PTCA; 82 (62%) of 131 had been refused CABG. Mortality over time was obtained from the Veterans Affairs Beneficiary Index Records Locator Subsystem. Predicted 30-day CABG-associated mortality was obtained from the Veterans Affairs Cardiac Risk Assessment Model. Mortality over time was expressed with Kaplan-Meier curves. RESULTS The observed 30-day angioplasty survival rate was 87% compared with the predicted surgical 30-day survival rate of 85.5%. In those patients who survived 6 months after angioplasty (84%), their subsequent 1-, 2-, 3-, 4- and 5-year survival rates were comparable to age-matched subjects in the U.S. census. Mortality in certain subsets known to be at very high risk for CABG-for example, patients who had a previous CABG-was not high in this cohort of elderly subjects. The extremely high risk subsets identified in this PTCA cohort (shock, heart failure, pressors required, balloon pump required) were relatively infrequent subsets. CONCLUSIONS For selected elderly patients with unstable angina deemed to be at "high risk" or even "prohibitive risk" for CABG, PTCA is an alternative revascularization strategy. The long-term mortality of successfully treated elderly patients is comparable to age-matched subjects. A prospective, multicenter, randomized trial of CABG versus PTCA, which includes patients > or = 70 years old, is being conducted (Veterans Affairs Cooperative Study 385: AWESOME).

Abstract
BACKGROUND This report describes the results of percutaneous transluminal coronary angioplasty (PTCA) in the Thrombolysis in Myocardial Ischemia (TIMI) IIIB Investigation. METHODS AND RESULTS PTCA was performed before hospital discharge in 444 of 1473 patients with either unstable angina pectoris or non-Q-wave myocardial infarction (NQWMI) enrolled in TIMI IIIB. Angiographic success was observed in 96.1% of patients. For the entire cohort, the cumulative incidences of death and infarction at 1 year were 2.0% and 8.2%, respectively. The periprocedural incidence of myocardial infarction was 2.7%; emergency coronary bypass surgery, 1.4%; and death, 0.5%. By 1 year of follow-up, 122 patients (28.0%, Kaplan-Meier) had an additional revascularization procedure, 75 (61.5%) had PTCA only, 30 (24.6%) had coronary bypass surgery only, and 17 (13.9%) had both procedures. The results of PTCA were not improved by routine pretreatment with intravenous tissue plasminogen activator (TPA). Periprocedural myocardial infarction was more common among patients receiving TPA than placebo (odds ratio [OR], 2.19; P = .03) and among those with unstable angina than those with NQWMI (OR, 15.5; P = .007). No difference in outcome was observed when patients were analyzed according to age (OR, 1.06; P = .092) or sex (OR, 1.54; P = .51). Variables predictive of poor outcome were PTCA within the first 24 hours of enrollment, PTCA site being the left anterior descending coronary artery, and unsuccessful angiography. CONCLUSIONS In TIMI IIIB, PTCA was performed for patients with unstable angina and NQWMI with a very high rate of angiographic success and a low incidence of complications. By 1 year, repeat revascularization was performed in 28.0% of patients. Routine pretreatment with thrombolysis did not enhance outcome.

Abstract
BACKGROUND Coronary angiography is indicated for many patients after acute myocardial infarction (AMI). There are a number of subgroups of AMI patients, however, for whom the indication for coronary angiography is not well established. METHODS AND RESULTS We developed a decision-analytic model for AMI in representative patient subgroups based on relevant clinical characteristics. The model estimates quality-adjusted life expectancy and direct lifetime costs for two strategies: coronary angiography and treatment guided by its results versus initial medical therapy without angiography. Decision tree chance node probabilities were estimated with the use of pooled data from randomized clinical trials and other relevant literature, costs were estimated with the use of the Medicare Part A database, and quality of life adjustments were derived from a survey of 1051 patients who had had a recent AMI. In our analysis, incremental cost-effectiveness ratios for coronary angiography and treatment guided by its result, compared with initial medical therapy without angiography, ranged between $17,000 and > $1 million per quality-adjusted year of life gained. Patient subgroups with severe postinfarction angina or a strongly positive exercise tolerance test (ETT) typically had cost-effectiveness ratios of < $50,000 per quality-adjusted year of life gained. In addition, most patient subgroups with a prior AMI had cost-effectiveness ratios of < $50,000 per quality-adjusted year of life gained, even with a negative ETT result. CONCLUSIONS In many patient subgroups after AMI, the cost-effectiveness of routine coronary angiography and treatment guided by its results compares favorably with other treatment strategies for coronary heart disease.

Abstract
Although coronary heart disease is the leading cause of death in women in most industrialized countries, much less research has been carried out on this topic to date than in men. This article gives an overview of psychosocial factors of coronary heart disease in women, focussing on psychosocial risk factors for coronary heart disease in women such as socioeconomic status, employment status, chronic troubling emotions, social support and bereavement/widowhood. A second focus lies on psychosocial adjustment in women once coronary heart disease has become manifest, i.e. well-being, return to work, sexual activity and rehabilitation outcome after a myocardial infarction or coronary artery bypass grafting. Via a computerized literature research in Medline, Psychlit and Sociofile over the period 1980-1994 all studies on these topics were collected and reviewed. Comparatively more research has been undertaken on psychosocial risk factors for than on psychosocial adjustment to coronary heart disease in women. Low social class, low educational attainment, the double loads of work and family, chronic troubling emotions and lack of social support emerge as documented risk factors in women. Regarding psychosocial adjustment to coronary heart disease in women, there is a paucity of data, and studies including large samples of women and adjusting for gender are warranted. Psychosocial adjustment in women after a myocardial infarction seems to be worse than in men, whereas results on adjustment after coronary artery bypass grafting are inconclusive. Return to work rates after myocardial infarction or coronary artery bypass grafting are significantly lower in women than in men. Data on sexual activity of women after myocardial infarction or coronary artery bypass grafting are scarce, and there seems to be a complete lack of physician counseling on this topic. Studies on rehabilitation outcome report poorer programme uptake, poorer adherence and significantly higher drop-out rates for women than for men, yet those women who complete cardiac rehabilitation show the same or even greater functional improvements than men.

Abstract
A prospective study comparing the long-term results of balloon angioplasty in patients over 75 years of age with those in a younger patient group is not available. A total of 192 consecutive patients aged > or = 75 years (group I) who underwent a balloon angioplasty were matched with 192 control patients aged 40 to 65 years (group II). The groups were matched for gender, angina pectoris class, left ventricular function, 1-, 2-, and 3-vessel coronary artery disease, and previous myocardial infarction. The mean follow-up was 40.4 months (range 0 to 110). Actuarial analysis (freedom from events) after 5 years yielded the following results for group I versus group II: free from death remained 77.1% versus 97.9% (p = 0.0001), from cardiac death 92.4% versus 97.9% (p = 0.049), and from angina pectoris 54.6% versus 75.1% (p = 0.03). The differences were not significant for those remaining free from myocardial infarction, repeat balloon angioplasty, or coronary artery bypass grafting. When elderly patients with complete revascularization (n = 127) were compared with a matched control group of 127 patients aged 40 to 65 years who underwent complete revascularization, there was only a significant difference in noncardiac death rates. We conclude that patients > 75 years of age have a significant higher cardiac and noncardiac death rate and a higher incidence of angina pectoris after successful balloon angioplasty. However, the incidence of reintervention and myocardial infarction is lower in the elderly. If complete revascularization is achieved in the elderly, then freedom from cardiac death and recurrence of angina pectoris would be comparable to that in younger patients.

Abstract
OBJECTIVES This study sought to determine whether in-hospital and intermediate-term posthospital outcomes have changed in elderly patients undergoing percutaneous transluminal coronary angioplasty from the period 1980 through 1989 to the period 1990 through 1992. BACKGROUND Although elderly patients have a higher incidence of procedure-related deaths and late recurrence of angina after coronary angioplasty, recent complication rates for angioplasty seem to be lower. METHODS From 1980 to 1989, 982 patients > or = 65 years old underwent nonemergent coronary angioplasty (group A). They were compared with 768 similar patients who had coronary angioplasty from 1990 to 1992 (group B). RESULTS Patients in group B were older than those in group A and had a higher mean concomitant disease score, a higher proportion of men and a greater proportion of patients with a previous myocardial infarction and previous coronary artery bypass surgery. Despite the increased complexity of the group B cohort, procedural success rates were higher, and rates of important in-hospital complications were much lower than those in group A. For group A versus group B, respectively, the technical success rate was 88.1% versus 93.5% (p < 0.001), in-hospital death rate 3.3% versus 1.4% (p = 0.014), emergency bypass surgery rate 5.5% versus 0.65% (p < 0.001) and incidence of in-hospital death or myocardial infarction 6.3% versus 3.4% (p < 0.005). However, intermediate-term posthospital event-free rates in hospital survivors did not decrease. The rate of death or myocardial infarction at 6 months was 4.7% in group A versus 7.1% in group B (p < 0.05). Survival free of acute myocardial infarction, bypass surgery, repeat coronary angioplasty or severe angina at 1 year was 66.7% in group A versus 54.9% in group B (p < 0.001). The combined in-hospital death/myocardial infarction rate plus that for the first 6 months after hospital dismissal was essentially equivalent for the two groups (10.3% vs. 9.9%, p = NS). CONCLUSIONS An increase in technical success rates and a reduction in short-term complication rates for coronary angioplasty in the elderly in recent years have not translated into an improved event-free survival rate, which continues to be influenced by important baseline characteristics of these high risk patients.

Abstract
In this study, 70 patients > or = 70 years of age admitted to the coronary care unit with non-Q-wave acute myocardial infarction (AMI) were followed prospectively for 1 year, and the clinical course in these patients was compared with that in 61 patients < 70 years with non-Q-wave AMI and 56 patients > or = 70 years with Q-wave AMI. Compared with the younger patients with non-Q-wave AMI, older patients were more likely to develop atrial fibrillation (23% vs 8%; p < 0.05) and congestive heart failure (53% vs 30%; p < 0.01), and less likely to receive thrombolytic therapy (9% vs 28%; p < 0.01), cardiac catheterization (41% vs 72%; p < 0.01), and coronary angioplasty (20% vs 39%; p < 0.05). Hospital mortality did not differ significantly between older and younger non-Q-wave AMI patients (10% vs 3%), but 1-year mortality was higher in the elderly (36% vs 16%; p = 0.02). Elderly patients with Q-wave AMI had more in-hospital complications, including death (25% vs 10%; p < 0.05), than elderly patients with non-Q-wave AMI. In contrast, postdischarge mortality was higher in elderly patients with non-Q-wave AMI, so that total mortality at 1 year was similar in the 2 groups. Overall, elderly patients with non-Q-wave AMI accounted for 62% of all deaths occurring during the first year after discharge (relative risk 2.6 compared with other groups; p < 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The influence of gender on the procedural outcome of directional coronary atherectomy (DCA) is controversial. This study of 373 consecutive patients (418 lesions) undergoing DCA demonstrates that the procedural success rate of DCA is significantly lower in women compared with men (72.7 vs. 82.9%, p = 0.011). Women have significantly smaller coronary arteries than men (2.5 mm vs. 2.7 mm, p = 0.028) and were older than men (66 vs. 61 years, p = 0.0001). Multivariate analysis identifies small coronary vessel size rather than female gender per se as an independent predictor of poor procedural outcome. Procedural success rates in women with coronary vessel size > or = 2.5 mm is significantly higher (92.2%) than in women with coronary vessel size < 2.5 mm (73.1%), and parallels that in men with vessel size > or = 2.5 mm (89.3%). Inability to engage the ostium of the coronary artery adequately with the guiding catheter and to cross the lesion with the atherectomy device is significantly more common in women compared with men. Major ischemic complication rates are similar in women and men (8.5 vs. 8.7%). Groin complications are significantly more common in women compared with men (13.5 vs. 2.9%). We conclude that procedural success rates in women may be improved by careful patient selection, with particular attention to small vessel size. DCA is best performed in vessels > 2.5 mm in diameter.

Abstract
AIMS This report reviews the outcome of percutaneous transluminal coronary angioplasty (PTCA) on patients aged 75 years or over at this institution, in order to provide statistics that may be useful in managing elderly patients. METHODS All elderly patients undergoing PTCA between January 1984 and December 1990 were included. Data concerning the PTCA procedure and short term (hospital stay) outcome were compared to those of all patients less than 75 years who underwent PTCA during the same period. Long term outcome was obtained for all surviving elderly patients. RESULTS One hundred and eleven procedures were performed on patients over 75 years, compared to 3183 procedures on patients under 75. The incidence of PTCA in the elderly increased to 6.7% of all procedures in 1990. Elderly patients were more symptomatic (97% vs 79% in patients under 75 years had Canadian Cardiovascular Society grade 3 or 4 angina), more frequently had the procedure performed urgently (39% vs 14%) and often (67%) had risk factors for PTCA (3 vessel disease, significant left ventricular dysfunction, or a complicating medical illness). Primary success rates (86% vs 90% in patients under 75 years), urgent coronary artery bypass grafting (1.8% vs 1.9%) and Q wave infarction (1.8% vs 1.0%) were similar in the two age groups. In the elderly, procedural difficulties requiring non standard equipment were common (61%), and in-hospital mortality was increased (4.5% vs 0.7%). Additionally, three patients died after discharge resulting in a 30 day mortality of 7.2%. A favourable long term outcome was obtained in 50% of patients at a mean follow up of 20 months. Unfavourable or neutral outcome was due to one or more of the following; death (16%), coronary artery bypass grafting (19%), acute myocardial infarction (7.5%) or significant residual angina (17%). CONCLUSIONS Highly symptomatic patients over 75 years constitute a high risk group for PTCA, with approximately half obtaining a favourable long term outcome.

Abstract
BACKGROUND Although the technical success rate of coronary angioplasty in the elderly in high, very old patients have increased risk of procedure-related death and late recurrence of severe angina. We proposed to determine baseline variables that predict early and intermediate-term failure of percutaneous transluminal coronary angioplasty (PTCA) in patients more than 65 so we could effectively stratify risk. METHODS AND RESULTS We studied 982 patients at least 65 years old who had urgent or elective PTCA (1980 through 1990). Follow-up (mean, 25 months) was obtained for all patients. Multiple baseline variables were analyzed with univariate and multivariate logistic regression to select independent ones to fit predictive models for in-hospital death or myocardial infarction (overall rate, 6.3%), total in-hospital adverse outcome (overall rate, 18.7%), cumulative survival free of myocardial infarction (overall rate, 15% at 3 years), and cumulative survival free of late nonfatal myocardial infarction, bypass surgery, repeat PTCA, or recurrent severe angina (overall rate, 47% at 3 years). The most heavily weighted parameter in the probability regression equation for each end point was the number of diseased coronary artery segments with at least 70% stenosis. Advanced age was less important. The number of concomitant medical illnesses was predictive of late outcome but not early in-hospital events. Lowest risk quintile versus highest risk quintile event rate was 2.9% versus 14% for acute myocardial infarction or death and 17.2% versus 29% for cumulative in-hospital events. For posthospital events at 3 years' follow-up, lowest risk quintile death or myocardial infarction rate was 4% versus 33% for highest risk quintile. For cumulative late adverse events at 3 years, the event rate was 28% versus 63% for the highest risk quintile. CONCLUSIONS These results stratify patients at high and low risk of early and intermediate-term success after PTCA and identify elderly patients in whom PTCA is most appropriate.
