Abstract
Objective Long-term survival after off-pump surgery in patients with low ejection fraction was investigated. Methods Three hundred forty-six patients with ejection fraction 30% or less with isolated off-pump coronary artery bypass surgery (OPCAB) were compared with a propensity matched historical group operated on-pump (ONCAB) and with data from literature after percutaneous coronary intervention and OPCAB surgery. Results The lower invasiveness of OPCAB contributed to a significantly better 30-day survival, shorter postoperative length of stay, and fewer in-hospital complications. Incomplete revascularization of the posterior and lateral territories of the heart correlated with higher 1-year mortality. The probability of survival for 8 years after OPCAB was 50.1% (n = 76) versus 49.7% (n = 82) for ONCAB without comparable data from literature for OPCAB or percutaneous coronary intervention in these high-risk patients. Conclusions OPCAB surgery in patients with low ejection fraction is a viable alternative but so far without demonstrable long-term survival advantage to ONCAB.

Abstract
BACKGROUND Patients with congestive heart failure (CHF) have higher rates of adverse outcomes after percutaneous coronary intervention (PCI). A comprehensive analysis of outcomes in patients with CHF in the current era has not been done. We studied the outcomes of patients with CHF who underwent PCI in the National Heart, Lung, and Blood Institute-sponsored Percutaneous Transluminal Coronary Angioplasty (PTCA) and Dynamic registries. METHODS We evaluated demographic and angiographic characteristics and the clinical outcomes of patients with CHF in the Dynamic Registry and the PTCA Registry, excluding patients with acute myocardial infarction. In the Dynamic Registry, patients with CHF (n = 503) were compared with patients without CHF (n = 4194), and patients with CHF with a preserved ejection fraction (EF) (n = 134) were compared with patients with CHF who have a reduced EF (n = 199). The patients with CHF in the 1997 through 2001 Dynamic Registry (n = 236) were then similarly compared with patients with CHF in the earlier PTCA Registry (n = 117). RESULTS In the Dynamic Registry, compared with patients without CHF, patients with CHF had a higher-risk clinical and angiographic profile, and a higher mortality rate both inhospital (2.6% vs 0.4%, P < or = .001) and at 1 year (13.1% vs 3.0%, P < .001). Patients with reduced EF had higher inhospital mortality rates and a trend toward higher mortality at 1 year. The patients with CHF in the Dynamic Registry compared with those in the PTCA Registry had a higher risk profile yet had significantly higher procedural success rates and improved clinical outcomes. CONCLUSIONS Although CHF remains a strong predictor of adverse outcomes after PCI, significant improvement seen in the past decade is likely related to improved procedural techniques and improved medical therapy.

Abstract
While earlier studies of balloon angioplasty (BA) in patients with left ventricular (LV) dysfunction suggested high late mortality, a study directly comparing coronary stenting and BA has not been performed. Since stenting provides a more durable revascularization, we sought to compare long-term survival in patients undergoing stenting vs BA in patients with decreased left ventricular ejection fractions (LVEF). We evaluated consecutive patient procedures performed in our institution from 1996 through 1999. Patients were considered part of the stent group if they received at least one stent. To be included, patients had to have a technically adequate angiographic LV gram with a calculated LVEF<or=50%. Patients with prior CABG were excluded. Mortality data was retrieved using the United States Social Security Death Index. Follow-up ranged from 3.5 to 6.5 years. Statistical analysis was performed and tests were significant with a P-value<0.05. A total of 238 patients fulfilled our criteria. Mean age was 57.5+/-12 years, mean LVEF was 39+/-10%, 67% were males, 71.5% received stents, 62% had a recent MI, and 19% died during follow-up. Overall 5-year survival was 84% for stenting and 77% for BA (P=NS). Patients with an LVEF<or=40% (n=110) had better survival at 5 years if they received a stent compared with BA alone (76% for stents vs. 53% for BA; P<0.05). Stenting was found to be significant predictor of late survival on Cox Hazard Regression analysis in patients with an LVEF<or=50% and LVEF<or=40%. This study demonstrates improved 5-year survival for patients undergoing stenting compared with balloon angioplasty in patients with LVEF<or=40%.

Abstract
Percutaneous coronary angioplasty (PTCA) in patients with depressed left ventricular ejection fraction (LVEF) is associated with increased acute and late mortality; in contrast to plain PTCA, results of stenting in these patients have not been characterized. To assess the current outcome of stenting in patients with LV dysfunction, results from 80 patients procedures were analyzed. Intervention for acute myocardial infarction (MI) was excluded; 21% of patients had unstable angina and 30% had a recent MI. Mean LVEF was 40 +/- 9% (range, 25-45%). Multivessel revascularization was done in 25 patients (31%), with a total of 114 lesions treated. Prophylactic intra-aortic balloon pump was used in only two patients. Angiographic and clinical success was achieved in 79/80 patients (99%). There were no in-hospital deaths, one patient (1%) had a non-Q-wave MI, and no patients required emergency bypass surgery (CABG). All patients completed at least 6 months follow-up (mean, 30 +/- 14 months): 64 patients (80%) remained asymptomatic, 4 (5%) had acute MI, and 5 (6%) died. In-stent restenosis occurred in five patients (6%); of these, three required repeat PTCA, three patients (4%) underwent subsequent elective CABG. Including patients with repeat intervention, 67 patients (84%) are clinically improved; actuarial event-free survival was 87% at 56-month follow-up. Thus, stenting in patients with impaired LVEF is associated with excellent outcome and lower mortality than previously reported for balloon angioplasty alone. Whether coronary stenting may be a therapeutic strategy equivalent to surgery in selected patients needs to be investigated in prospective randomized trials.

Abstract
Outcome studies of percutaneous coronary intervention (PCI) with conventional balloon angioplasty have established increased in-hospital and 1-year mortality in patients with left ventricular (LV) dysfunction compared with others. It is unclear whether recent PCI practice innovations, including stents and adjunctive pharmacotherapy, have made PCI safer and more effective in patients with LV dysfunction. We evaluated the influence of LV ejection fraction (EF) indexes on in-hospital and 1-year outcomes in 1,458 patients within the National Heart, Lung, and Blood Institute-sponsored Dynamic Registry. Patients (n = 300) with acute myocardial infarction were excluded. The remaining 1,158 patients were subdivided into 3 categories: group 1, EF <or=40% (n = 166); group 2, EF 41% to 49% (n = 126); and group 3, EF >or=50% (n = 866). We determined the frequency of individual and composite adverse events (death/myocardial infarction [MI]/coronary artery bypass grafting) at discharge and 1 year. In the Dynamic Registry patients, mean EF in the 3 groups was 32%, 45%, and 62% and in-hospital mortality was 3.0%, 1.6%, and 0.1%, respectively (p <0.001). The composite end point of death/MI was also significant, but other in-hospital adverse events did not differ between groups. The respective mortality rates were 11.0%, 4.5%, and 1.9% (p <0.001) after 1 year. The composite end points of death/MI and death/MI/coronary artery bypass grafting also occurred more frequently in group 1 patients. Thus, significant LV dysfunction was still associated with increased in-hospital and 1-year mortality in patients having contemporary PCI.

Abstract
OBJECTIVE To assess the clinical outcome of successful percutaneous transluminal coronary angioplasty (PTCA) in patients with poor ventricular function. METHODS Analysis of angiographic, echocardiographic and clinical records of patients with severe LV dysfunction who underwent PTCA from January 1, 1995 to December 31, 1997 was undertaken. Forty-one patients aged 63+/-10 years, 36 men, all with significant coronary artery disease and impaired LV function (fractional shortening, FS<or=20%) were identified. Patients' data before and after angioplasty were analyzed. RESULTS Post PTCA: angiographic success was 95.2%. Major complications occurred in 19.5% and hospital mortality was 2.7%. At 6 months after PTCA:LV fractional shortening (FS) increased from 15.9+/-3.4% to 19.6+/-6.6%, P=0.02 and consequently cardiac output from 4.28+/-0.98 to 5.34+/-1.77 l/min, P<0.01. Change in at least one class of angina and cardiac functional status was observed in 46% of patients, P<0.001, and this was maintained to the end of the year. After 12 months follow-up: restenosis occurred in 10.8%; mortality was 5.4%; event-free and actuarial survivals were 62.3% and 91.9%, respectively. CONCLUSIONS In patients with severe LV dysfunction, continued symptomatic improvement can be achieved with successful coronary angioplasty. This is associated with significant recovery of LV systolic function and cardiac output. In order to minimize procedure-related complications, careful patient selection should be considered.

Abstract
BACKGROUND Published experience with coronary angioplasty in patients with severely depressed left ventricular (LV) ejection fraction indicates that procedural complications are more frequent in such patients than in those with normal or near normal LV function. Although the immediate outcomes of transcatheter revascularization in unselected populations have improved substantially since the procedures upon which these reports were based were performed, outcomes with this subset of patients has not been recently reviewed. HYPOTHESIS This study was undertaken to document the results of the application of current transcatheter technology to this patient subset. METHODS We analyzed data from 194 consecutive patients with a visually estimated LV ejection fraction < 30%, who underwent coronary angioplasty in this institution between January 1, 1995, and April 30, 1996, and compared their outcomes with those of 1,390 patients with normal LV function treated concurrently. RESULTS Angiographic success in the two groups was similar. The hospital mortality of the patients with low ejection fraction was higher (2.6 vs. 0.6%, p = 0.02) than in concurrently treated patients with normal LV function. Other procedural complications were no more frequent than in such patients. Late mortality in patients with low ejection fraction was 16%, a similar value to that in older reports. CONCLUSION Compared with older reports, current hospital outcomes of coronary angioplasty are improved in patients with severely depressed LV function. Unfortunately, late outcomes are not demonstrably better.

Abstract
To assess the effects of coronary angioplasty in patients with severe left ventricular dysfunction, the results of procedures, performed between 1987 and 1991, in 100 patients (90 male) with left ventricular function < or = 0.35 (range, 0.20 to 0.35) and anginal symptoms were analyzed. Mean age was 62 +/- 10 years (range, 38 to 85 years). Ninety-five patients had previous myocardial infarction and 27 patients had previous coronary artery bypass grafting. Unstable angina was present in 81 percent of patients. Single-vessel disease was present in 6 patients, double vessel was present in 31 patients, and triple-vessel disease was present in 63 patients. Percutaneous transluminal coronary angioplasty (PTCA) was attempted on 164 vessels, 27 of these with chronic total occlusion. The overall angiographic success rate was 84 percent. Myocardial infarction occurred in four patients, six patients underwent urgent coronary bypass surgery, and seven patients died of cardiac causes. There was a 9 percent incidence of total in hospital mortality. Major complications were significantly more frequent in patients with triple-vessel disease. Clinical success was achieved in 75 patients, 55 of these with incomplete revascularization. Long-term follow-up (mean, 19 +/- 7 months) was available in all patients with clinical success. Thirteen patients had repeated PTCA, 8 patients had coronary surgery, and 13 patients died. In conclusion, in patients with severe left ventricular dysfunction, acute complications and late mortality rate are high. Patients with triple-vessel disease are a higher risk subset and have no long-term benefits by PTCA.

Abstract
The risks and long-term outcome after 845 elective percutaneous transluminal coronary angioplasties (PTCA) in patients with left ventricular (LV) dysfunction (ejection fraction less than or equal to 40%) were examined. Procedural results were compared with 8,117 consecutive procedures in patients with ejection fractions greater than 40%. The patients with LV dysfunction were older (63 vs 60 years, p less than 0.01), had a greater incidence of prior myocardial infarction (84 vs 45%, p less than 0.001), prior bypass surgery (39 vs 21%, p less than 0.001), 3-vessel disease (62 vs 33%, p less than 0.001), and class IV angina (48 vs 41%, p less than 0.01) than the control group. Angiographic success was lower (93 vs 95%, p less than 0.01), and overall procedural mortality was increased ( 4 vs 1%, p less than 0.001) in the study group. Emergency surgery rates were identical (2%). No significant difference was found in rates of nonfatal Q-wave myocardial infarction (2 vs 1%). At mean follow-up of 33.5 months, 15% of the patients with LV dysfunction required late bypass surgery, 27% underwent repeat PTCA, and 59% were angina free. Actuarial survival at 1 and 4 years was 87 and 69%, respectively. Cox regression analysis identified 3-vessel disease, age greater than or equal to 70 years, class IV angina and incomplete revascularization as correlates of long-term mortality. These data suggest that PTCA may be an effective treatment for coronary artery disease in patients with LV dysfunction.

Abstract
The prospectively collected data of 1,001 multivessel coronary disease patients who underwent percutaneous transluminal angioplasty (PTCA) was analyzed after categorization into single vessel angioplasty (SVA; group I) and multiple vessel angioplasty (MVA; group II) PTCA groups, which were each compartmentalized into "simple" (group A) and "complex" (group B) cohorts. Patients were assigned to the SVA or MVA group according to the physician's pre-PTCA assessment of how many lesions would be attempted (intention to treat) and not the number of lesions actually attempted. A "simple" patient was more likely than a "complex" patient to be clinically improved after PTCA whether or not the patient had a single dilatation (90% vs 78%; P less than 0.05) or multiple dilatations (97% vs 94%; P<0.05). Similarly, a lesion(s) was more likely to be successfully dilated in the "simple" than in the "complex" group (SVA: 90% vs 82%, P less than 0.05; MVA: 97% vs 91%, P<0.05). In addition, occluded vessels in the MVA group were more likely to be recanalized than in the SVA group (73% vs 44%, P less than 0.05). Group I-A patients had a significantly increased (10%) incidence of emergency bypass surgery. Follow-up, at 84 months, showed that "simple" cohorts had a better survival than the "complex" cohorts (MVA: 95% vs 71%, P less than 0.05; SVA: 90% vs 72%, P less than 0.05); and, nearly two thirds of all successful PTCA patients were angina free.(ABSTRACT TRUNCATED AT 250 WORDS)
