RESUMEN
BACKGROUND: The efficacy of optimal medical therapy (OMT) with or without revascularization therapy in patients with stable coronary artery disease (SCAD) remains controversial. We performed a meta-analysis of randomized controlled trials (RCTs) that compared OMT with or without revascularization therapy for SCAD patients. METHODS: Studies were searched in PubMed, EMBASE, and the Cochrane Central Register of Clinical Trials from January 1, 2005, to December 30, 2023. The main efficacy outcome was a composite of all-cause death, myocadiac infarction, revascularization, and cerebrovascular accident. Results were pooled using random effects model and fixed effects model and are presented as odd ratios (ORs) with 95% confidence intervals (CI). RESULTS: Ten studies involving 12,790 participants were included. The arm of OMT with revascularization compared with OMT alone was associated with decreased risks for MACCE (OR 0.55 [95% CI 0.38-0.80], I²=93%, P = 0.002), CV death (OR 0.84 [95% CI 0.73-0.97], I²=36%, P = 0.02), revascularization (OR 0.32 [95% CI 0.20-0.50], I²=92%, P < 0.001), and MI (OR 0.85 [95% CI 0.76-0.96], I²=45%, P = 0.007). While there was no significant difference between OMT with revascularization and OMT alone in the odds of all-cause death (OR 0.94 [95% CI 0.84-1.05], I²=0%, P = 0.30). CONCLUSIONS: The current updated meta-analysis of 10 RCTs shows that in patients with SCAD, OMT with revascularization would reduce the risk for MACCE, cardiovascular death, and MI. However, the invasive strategy does not decrease the risks for all-cause mortality when comparing with OMT alone.

BACKGROUND: Complete revascularization improves cardiovascular outcomes compared with culprit-only revascularization in patients with acute myocardial infarction ([MI]; ST-segment-elevation MI or non-ST-segment-elevation MI) and multivessel coronary artery disease. However, the timing of complete revascularization (single-setting versus staged revascularization) is uncertain. The aim was to compare the outcomes of single-setting complete, staged complete, and culprit vessel-only revascularization in patients with acute MI and multivessel disease. METHODS: PubMed, EMBASE, and clinicaltrials.gov databases were searched for randomized controlled trials that compared 3 revascularization strategies. RESULTS: From 16 randomized controlled trials that randomized 11 876 patients with acute MI and multivessel disease, both single-setting complete and staged complete revascularization reduced primary outcome (cardiovascular mortality/MI; odds ratio [OR], 0.52 [95% CI, 0.41-0.65]; OR, 0.74 [95% CI, 0.62-0.88]), composite of all-cause mortality/MI (OR, 0.52 [95% CI, 0.40-0.67]; OR, 0.78 [95% CI, 0.67-0.91]), major adverse cardiovascular event (OR, 0.42 [95% CI, 0.32-0.56]; OR, 0.62 [95% CI, 0.47-0.82]), MI (OR, 0.39 [95% CI, 0.26-0.57]; OR, 0.73 [95% CI, 0.59-0.90]), and repeat revascularization (OR, 0.30 [95% CI, 0.18-0.47]; OR, 0.46 [95% CI, 0.30-0.71]) compared with culprit-only revascularization. Single-setting complete revascularization reduced cardiovascular mortality/MI (OR, 0.70 [95% CI, 0.55-0.91]), major adverse cardiovascular event (OR, 0.67 [95% CI, 0.50-0.91]), and all-cause mortality/MI driven by a lower risk of MI (OR, 0.53 [95% CI, 0.36-0.77]) compared with staged complete revascularization. Single-setting complete revascularization ranked number 1, followed by staged complete revascularization (number 2) and culprit-only revascularization (number 3) for all outcomes. The results were largely consistent in subgroup analysis comparing ST-segment-elevation MI versus non-ST-segment-elevation MI cohorts. CONCLUSIONS: Single-setting complete revascularization may offer the greatest reductions in cardiovascular events in patients with acute MI and multivessel disease. A large-scale randomized trial of single-setting complete versus staged complete revascularization is warranted to evaluate the optimal timing of complete revascularization.

OBJECTIVE: Infective endocarditis (IE)-related ST elevation myocardial infarction (STEMI) is extremely rare. A clear clinical consensus is lacking regarding the management of this emergency. In this study, we aimed to describe the clinical outcomes of treatment strategies in this patient population. METHODS: The study population comprised 19 retrospectively evaluated patients (nine women; mean age 52±11.8 years) with a diagnosis of IE-related STEMI. Transesophageal echocardiography detected vegetation in all the patients. The study population was divided into two groups on the basis of in-hospital mortality. RESULTS: Major clinical manifestations included dyspnea (89.5%), fever (78.9%), and chest pain (63.2%). Catheter-based coronary angiography was performed in all the patients. The causative agent was isolated in all the cases, and Staphylococcus aureus was identified in seven (36.8%). The most common infarction was in the left anterior descending artery (n=12 [63.2%]). The treatment strategy consisted of mechanical thrombectomy (n=1), valve replacement following stent implantation (n=5), direct balloon angioplasty (n=4), valve replacement along with coronary artery bypass grafting (CABG; n=6), and medical follow-up (n=3). Moreover, thrombolysis in myocardial infarction III flow was significantly higher in the survival group (100% vs. 0%, p<0.001). All these patients preferred CABG or stent implantation for revascularization. CONCLUSION: The current data suggest that a revascularization strategy with stent implantation or revascularization with CABG has a lower mortality rate in patients with IE-related STEMI.

Abstract Background Prolonged mechanical ventilation (MV) after cardiac surgery imposes a significant burden on the patient in terms of morbidity and financial hospital costs. Objective To develop a risk score model to predict prolonged MV in patients undergoing coronary artery bypass grafting (CABG) surgery. Methods This was a historical cohort study of 4165 adult patients undergoing CABG between January 1996 and December 2016. MV for periods ≥ 12 hours was considered prolonged. Logistic regression was used to examine the relationship between risk predictors and prolonged MV. The variables were scored according to the odds ratio. To build the risk score, the database was randomly divided into 2 parts: development data set (2/3) with 2746 patients and internal validation data set (1/3) with 1419 patients. The final score was validated in the total database and the model's accuracy was tested by performance statistics. Significance was established at p < 0.05. Results Prolonged MV was observed in 783 (18.8%) patients. Predictors of risk were age ≥ 65 years, urgent/emergency surgery, body mass index ≥ 30 kg/m2, chronic kidney disease, chronic obstructive pulmonary disease, and cardiopulmonary bypass time ≥ 120 minutes. The area under the ROC curve was 0.66 (95% CI, 0.64-0.68; p<0.001), the Hosmer-Lemeshow chi-square test was χ2: 3.38 (p=0.642), and Pearson's correlation was r = 0.99 (p<0.001), indicating the model's satisfactory ability to predict the occurrence of prolonged MV. Conclusion Selected variables allowed the construction of a simplified risk score for daily practice, which may classify the patients as having low, moderate, high, and very high risk.

BACKGROUND: Renal function plays a significant role in the prognosis and management of patients with multi-vessel coronary artery disease (CAD) referred for revascularization. Current data lack precise risk stratification using estimated glomerular filtration rate (eGFR) and creatinine clearance. METHODS: This prospective study includes a three-year follow-up of 1112 consecutive patients with multi-vessel CAD enrolled in the 22 hospitals in Israel that perform coronary angiography. RESULTS: The Mayo formula yielded the highest mean eGFR (90 ± 26 mL/min per 1.73m2) and chronic kidney disease-epidemiology collaboration (CKD-EPI) the lowest (76 ± 24 mL/min per 1.73m2). Consequently, the Mayo formula classified more patients (56%) as having normal renal function. There was a significant and strong correlation between the values obtained from all five formulas using Cockcroft-Gault as the reference formula: Mayo: r = 0.80, p < 0.001; CKD-EPI: r = 0.87, p < 0.001; modification of diet in renal disease (MDRD): r = 0.84, p < 0.001; inulin clearance-based: r = 0.99, p < 0.001). Multivariable analysis demonstrated that decreased renal function is an independent predictor of 3-year mortality in all five formulas, with risk increasing by 15-25% for each 10-unit decrease in eGFR. Despite the similarities between the formulas, the ability to predict mortality was highest in the Mayo formula and lowest in MDRD. CONCLUSIONS: Our data suggest that while the Mayo formula is not currently recommended by any nephrology guidelines, it may be an alternative formula to predict mortality among patients with multivessel CAD, including to the widely used MDRD formula.

BACKGROUND: Patients with critical limb-threatening ischemia (CLTI) have had poor long-term survival after lower extremity revascularization owing to coexistent coronary artery disease. A new cardiac diagnostic test, coronary computed tomography-derived fractional flow reserve (FFRCT), can identify patients with ischemia-producing coronary stenosis who might benefit from coronary revascularization. We sought to determine whether the diagnosis of silent coronary ischemia before limb salvage surgery with selective postoperative coronary revascularization can reduce the incidence of adverse cardiac events and improve the survival of patients with CLTI compared with standard care. METHODS: Patients with CLTI and no cardiac history or symptoms who had undergone preoperative testing to detect silent coronary ischemia with selective postoperative coronary revascularization (group I) were compared with patients with standard preoperative cardiac clearance and no elective postoperative coronary revascularization (group II). Both groups received guideline-directed medical care. Lesion-specific coronary ischemia in group I was defined as FFRCT of ≤0.80 distal to a stenosis, with severe ischemia defined as FFRCT of ≤0.75. The endpoints included all-cause death, cardiovascular (CV) death, myocardial infarction (MI), major adverse CV events (i.MACE; CV death, MI, unplanned coronary revascularization, stroke) through 2 years of follow-up. RESULTS: Groups I (n = 111) and II (n = 120) were similar in age (66 ± 9 vs 66 ± 7 years), gender (78% vs 83% men), comorbidities, and surgery performed. In group I, unsuspected, silent coronary ischemia was found in 71 of 103 patients (69%), with severe ischemia in 58% and left main coronary ischemia in 8%. Elective postoperative coronary revascularization was performed in 47 of 71 patients with silent ischemia (66%). In group II, the status of silent coronary ischemia was unknown. The median follow-up was >2 years for both groups. The 2-year outcomes for groups I and II were as follows: all-cause death, 8.1% and 20.0% (hazard ratio [HR], 0.38; 95% confidence interval [CI], 0.18-0.84; P = .016); CV death, 4.5% and 13.3% (HR, 0.32; 95% CI, 0.11-0.88; P = .028); MI, 6.3% and 17.5% (HR, 0.33; 95% CI, 0.14-0.79; P = .012); and major adverse CV events, 10.8% and 23.3% (HR, 0.44; 95% CI, 0.22-0.88; P = .021), respectively. CONCLUSIONS: The preoperative evaluation of patients with CLTI and no known coronary artery disease using coronary FFRCT revealed silent coronary ischemia in two of every three patients. Selective coronary revascularization of patients with silent coronary ischemia after recovery from limb salvage surgery resulted in fewer CV deaths and MIs and improved 2-year survival compared with patients with CLTI who had received standard cardiac evaluation and care. Prospective controlled studies are required to further define the role of FFRCT in the evaluation and treatment of patients with CLTI.

The red blood cell distribution width (RDW) measures the variability in the size of circulating erythrocytes. Previous studies suggested a powerful correlation between RDW obtained from a standard complete blood count and cardiovascular diseases in both primary and secondary cardiovascular prevention. The current study aimed to evaluate the prognostic role of RDW in patients undergoing cardiac rehabilitation after myocardial revascularization and/or cardiac valve surgery. The study included 1.031 patients with available RDW levels, prospectively followed for a mean of 4.5 ± 3.5 years. The mean age was 68 ± 12 years, the mean RDW was 14.7 ± 1.8%; 492 patients (48%) underwent cardiac rehabilitation after myocardial revascularization, 371 (36%) after cardiac valve surgery, 102 (10%) after valve-plus-coronary artery by-pass graft surgery, 66 (6%) for other indications. Kaplan-Meier analysis and Cox hazard analysis were used to associate RDW with mortality. Kaplan-Meier analysis demonstrated worse survival curves free from overall (log-rank p < 0.0001) and cardiovascular (log-rank p < 0.0001) mortality in the highest RDW tertile. Cox analysis showed RDW levels correlated significantly with the probability of overall (HR 1.26; 95% CI 1.19-1.32; p < 0.001) and cardiovascular (HR 1.31; 95% CI 1.23-1.40; p < 0.001) mortality. After multiple adjustments for cardiovascular risk factors, hemoglobin, hematocrit, C-reactive protein, microalbuminuria, atrial fibrillation, glomerular filtration rate,left ventricular ejection fraction and number of exercise training sessions attended, the increased risk of overall (HR 1.10; 95% CI 1.01-1.27; p = 0.039) and cardiovascular (HR 1.13; 95% CI 1.01-1.34; p = 0.036)mortality with increasing RDW values remained significant. The RDW represents an independent predictor of overall and cardiovascular mortality in secondary cardiovascular prevention patients undergoing cardiac rehabilitation.

BACKGROUND: Outcomes data for a durable-polymer everolimus-eluting stent (EES) at extended long-term follow-up in patients with ST-segment elevation myocardial infarction (STEMI) are unknown. OBJECTIVES: The aim of this study was to assess the 10-year outcomes of patients enrolled in the EXAMINATION (A Clinical Evaluation of Everolimus Eluting Coronary Stents in the Treatment of Patients With ST-Segment Elevation Myocardial Infarction) trial. METHODS: The EXAMINATION-EXTEND (10-Years Follow-Up of the EXAMINATION Trial) study is an investigator-driven 10-year follow-up of the EXAMINATION trial, which randomly assigned 1,498 patients with STEMI in a 1:1 ratio to receive either EES (n = 751) or bare-metal stents (n = 747). The primary endpoint was a patient-oriented composite endpoint of all-cause death, any myocardial infarction, or any revascularization. Secondary endpoints included a device-oriented composite endpoint of cardiac death, target vessel myocardial infarction, or target lesion revascularization; the individual components of the combined endpoints; and stent thrombosis. RESULTS: Complete 10-year clinical follow-up was obtained in 94.5% of the EES group and 95.9% of the bare-metal stent group. Rates of the patient-oriented composite endpoint and device-oriented composite endpoint were significantly reduced in the EES group (32.4% vs. 38.0% [hazard ratio: 0.81; 95% confidence interval: 0.68 to 0.96; p = 0.013] and 13.6% vs. 18.4% [hazard ratio: 0.72; 95% confidence interval: 0.55 to 0.93; p = 0.012], respectively), driven mainly by target lesion revascularization (5.7% vs. 8.8%; p = 0.018). The rate of definite stent thrombosis was similar in both groups (2.2% vs. 2.5%; p = 0.590). No differences were found between the groups in terms of target lesion revascularization (1.4% vs. 1.3%; p = 0.963) and definite or probable stent thrombosis (0.6% vs. 0.4%; p = 0.703) between 5 and 10 years. CONCLUSIONS: At 10-year follow-up, EES demonstrated confirmed superiority in combined patient- and device-oriented composite endpoints compared with bare-metal stents in patients with STEMI requiring primary percutaneous coronary intervention. Between 5- and 10-year follow-up, a low incidence of adverse cardiovascular events related to device failure was found in both groups. (10-Years Follow-Up of the EXAMINATION Trial; NCT04462315).

BACKGROUND: There is a paucity of data regarding acute phase (in-hospital and 30-day) major adverse cardiac events (MACE) following ST-segment elevation myocardial infarction (STEMI) in Bangladesh. This study aimed to document MACE during the acute phase post-STEMI to provide information. METHODS: We enrolled STEMI patients of the National Institute of Cardiovascular Disease, Dhaka, Bangladesh, from August 2017 to October 2018 and followed up through 30 days post-discharge for MACE, defined as the composite of all-cause death, myocardial infarction, and coronary revascularization. Demographic information, cardiovascular risk factors, and clinical data were registered in a case report form. The Cox proportional hazard model was used for univariate and multivariate analysis to identify potential risk factors for MACE. RESULTS: A total of 601 patients, mean age 51.6 ± 10.3 years, 93% male, were enrolled. The mean duration of hospital stay was 3.8 ± 2.4 days. We found 37 patients (6.2%) to experience an in-hospital event, and 45 (7.5%) events occurred within the 30 days post-discharge. In univariate analysis, a significantly increased risk of developing 30-day MACE was observed in patients with more than 12 years of formal education, diabetes mellitus, or a previous diagnosis of heart failure. In a multivariate analysis, the risk of developing 30-day MACE was increased in patients with heart failure (hazard ratio = 4.65; 95% CI 1.64-13.23). CONCLUSIONS: A high risk of in-hospital and 30-day MACE in patients with STEMI exists in Bangladesh. Additional resources should be allocated providing guideline-recommended treatment for patients with myocardial infarction in Bangladesh.

Changes in ventilatorymechanics and their consequent pulmonary complications are common after surgical procedures, particularly in cardiac surgery (CS), and may be associated with both preoperative history and surgical circumstances. This study aims to compare ventilatory mechanics in the moments before and after cardiac surgery (CS), describing how pulmonary complications occurred. An experimental, uncontrolled study was conducted, of the before-and-after type, and with a descriptive and analytical character. It was carried out in a private hospital in the city of Salvador, Bahia, Brazil, and involved 30 adult patients subjected to CS. In addition to clinical and epidemiological variables, minute volume (VE), respiratory rate (RR), tidal volume (VT), forced vital capacity (FVC), maximum inspiratory pressure (MIP), and peak expiratory flow (PEF) were also recorded. Data were collected in the following moments: preoperative (PRE-OP) period, immediate postoperative (IPO) period, and 1stpostoperative day (1stPOD). The sample was aged 48.1 ± 11.8 years old and had a body mass index of 25.5 ± 4.9 kg m-2; 60% of the patients remained on mechanical ventilation for less than 24 hours (17.5 [8.7-22.9] hours). There was a significant reduction in VT, FVC, MIP and PEF when PRE-OP versus IPO, and PRE-OP versus 1stPOD were compared (p < 0.05). There were no significant changes between IPO and the 1stPOD. The highest incidence of pulmonary complications involved pleural effusion (50% of the patients). This study showed that patients subjected to CS present significant damage to ventilatory parameters after the surgery, especially in the IPO period and on the 1stPOD. It is possible that the extension of this ventilatory impairment has led to the onset of postoperative pulmonary complications.

The advantages of an early invasive strategy in non-ST-elevation acute coronary syndromes (NSTE-ACS) are well documented. Less clear is the ideal time to perform it (within 24 h, within 72 h, or during hospitalization after positive non-invasive testing for ischemia). In particular, the class IA recommendation for coronary angiography within 24 h in patients with high-risk NSTE-ACS is controversial. Randomized clinical trials and meta-analyses show neutral effects on mortality, while significant positive results are observed only for secondary outcomes (mainly ischemic recurrences). Favorable effects on major cardiovascular events are reported only in the subgroup analysis of a single randomized trial (TIMACS) or in several trials included in the meta-analyses. Thus, these results are far from conclusive and should stimulate new randomized clinical studies to support them. In fact, the logistical implications that this recommendation implies deserve stronger evidence. It is clear that all patients with NSTE-ACS, especially if high-risk, should have the opportunity to undergo a coronary angiogram during hospitalization. However, in the real world, the strict timeline of the international guidelines may be difficult to follow. Therefore, indications that take into account resource availability and the organizational context should be developed. Several regional indications suggest that even in high-risk patients the 24 h time limit for the invasive strategy should not be mandatory, but timing of angiography should be calibrated on clinical presentation and logistical resources, without any a priori automatism.

OBJECTIVES: The aim of this study was to evaluate the clinical and anatomical features to predict the long-term outcomes in patients with fractional flow reserve (FFR)-guided deferred lesions, verified by intravascular ultrasound (IVUS). BACKGROUND: Deferral of nonsignificant lesion by FFR is associated with a low risk of clinical events. However, the impact of combined information on clinical and anatomical factors is not well known. METHODS: The study included 459 patients with 552 intermediate lesions who had deferred revascularization on the basis of a nonischemic FFR (>0.80). Grayscale IVUS was examined simultaneously. The primary endpoint was patient-oriented composite outcome (POCO) (a composite of all-cause death, myocardial infarction, and any revascularization) during 5-year follow-up. RESULTS: The rate of 5-year POCO was 9.8%. Diabetes mellitus (hazard ratio: 3.50; 95% confidence interval [CI]: 1.86 to 6.57; p < 0.001), left ventricular ejection fraction ≤40% (hazard ratio: 4.80; 95% CI: 1.57 to 14.63; p = 0.006), and positive remodeling (hazard ratio: 2.04; 95% CI: 1.03 to 4.03; p = 0.041) were independent predictors for POCO. When the lesions were classified according to the presence of the adverse clinical characteristics (diabetes, left ventricular ejection fraction ≤40%) or adverse plaque characteristics (positive remodeling, plaque burden ≥70%), the risk of POCO was incrementally increased (4.3%, 13.6%, and 21.3%, respectively; p < 0.001). CONCLUSIONS: In patients with FFR-guided deferred lesions, 5-year clinical outcomes were excellent.

Background Few studies have investigated optimal revascularization strategies in non-ST-segment-elevation myocardial infarction with multivessel disease. We investigated 3-year clinical outcomes according to revascularization strategy in patients with non-ST-segment-elevation myocardial infarction and multivessel disease. Methods and Results This retrospective, observational, multicenter study included patients with non-ST-segment-elevation myocardial infarction and multivessel disease without cardiogenic shock. Data were analyzed at 3 years according to the percutaneous coronary intervention strategy: culprit-only revascularization (COR), 1-stage multivessel revascularization (MVR), and multistage MVR. The primary outcome was major adverse cardiac events (MACE: a composite of all-cause death, nonfatal spontaneous myocardial infarction, or any repeat revascularization). The COR group had a higher risk of MACE than those involving other strategies (COR versus 1-stage MVR; hazard ratio, 0.65; 95% CI, 0.54-0.77; P<0.001; and COR versus multistage MVR; hazard ratio, 0.74; 95% CI, 0.57-0.97; P=0.027). There was no significant difference in the incidence of MACE between 1-stage and multistage MVR (hazard ratio, 1.14; 95% CI, 0.86-1.51; P=0.355). The results were consistent after multivariate regression, propensity score matching, inverse probability weighting, and Bayesian proportional hazards modeling. In subgroup analyses stratified by the Global Registry of Acute Coronary Events score, 1-stage MVR lowered the risk of MACE compared with multistage MVR in low-to-intermediate risk patients but not in patients at high risk. Conclusions MVR reduced 3-year MACE in patients with non-ST-segment-elevation myocardial infarction and multivessel disease compared with COR. However, 1-stage MVR was not superior to multistage MVR for reducing MACE except in low-to-intermediate risk patients.

To address many uncertainties in the acute care of patients with acute myocardial infarction (AMI) in proportion to increasing age, we underwent the nationwide current survey consisted of 11,676 patients with AMI based on the database of the Japanese Acute Myocardial Infarction Registry between January 2011 and December 2013 to figure out how difference of clinical profiles and outcomes between coronary revascularization and conservative treatments for AMI. Clinical profiles in a total of 763 patients with AMI with conservative treatments (7% of all) were characterized as more elderly women (median age, 71 yeas vs. 68 years, p < 0.0001, male, 71% vs. 76%, p = 0.0008), high Killip class (Killip class I, 61% vs. 75%, p < 0.0001), and non-ST-segment elevation AMI (37% vs. 27%, p < 0.0001) as compared with 10,913 with coronary revascularization, with a consequence of more than twofold higher in-hospital mortality (12% vs. 5%, p < 0.0001). When compared with conservative treatments, highly effective of coronary revascularization to decrease in-hospital mortality was found in patients with ST-segment elevation AMI (6% vs. 16%, p < 0.0001), while these advantages were not evident in those with non-ST-segment elevation AMI (4% vs. 6%, p = 0.1107), especially with high Killip class, regardless of whether or not propensity score matching of clinical characteristics. A risk-adapted allocation of invasive management therefore may have the potential of benefiting patients with non-ST-segment elevation AMI, in particular elders.

Intraaortic balloon pump (IABP) counterpulsation, introduced more than 50 years ago, remains the most commonly utilized mechanical circulatory support device for patients with cardiogenic shock and myocardial ischemia, despite lack of definitive proof regarding its outcome in these patients. Part I of this review focused on the history of counterpulsation, physiologic principles, technical considerations, and evidence for its use in cardiogenic shock; Part II will discuss periprocedural uses for IABP counterpulsation and review advances in technology, including the emergence of alternative mechanical circulatory support devices that have influenced IABP utilization.

BACKGROUND: Hybrid coronary revascularization (HCR) constitutes a left internal mammary artery graft to the left anterior descending (LAD) coronary artery, coupled with percutaneous coronary intervention (PCI) for non-LAD lesions. This management strategy is not commonly offered to patients with complex multivessel disease. Our objective was to evaluate 8-year survival in patients with triple-vessel disease (TVD) treated by HCR, compared with that of concurrent matched patients managed by traditional coronary artery bypass grafting (CABG) or multivessel PCI. METHODS: A retrospective review was undertaken of 4805 patients with TVD who presented between January 2009 and December 2016. A cohort of 100 patients who underwent HCR were propensity-matched with patients treated by CABG or multivessel PCI. The primary endpoint was all-cause mortality at 8 years. RESULTS: Patients with TVD who underwent HCR had similar 8-year mortality (5.0%) as did those with CABG (4.0%) or multivessel PCI (9.0%). A composite endpoint of death, repeat revascularization, and new myocardial infarction, was not significantly different between patient groups (HCR 21.0% vs CABG 15.0%, P = .36; HCR 21.0% vs PCI 25.0%, P = .60). Despite a higher baseline synergy between percutaneous coronary intervention with taxus and cardiac surgery(SYNTAX) score, HCR was able to achieve a lower residual SYNTAX score than multivessel PCI (P = .001). CONCLUSIONS: In select patients with TVD, long-term survival and FREEDOM from major adverse cardiovascular events after HCR are similar to that seen after traditional CABG or multivessel PCI. HCR should be considered for patients with multivessel disease, presuming a low residual SYNTAX score can be achieved.

Intraaortic balloon pump counterpulsation is the most common form of mechanical circulatory support used in patients with myocardial ischemia and cardiogenic shock. The physiologic principles of counterpulsation include diastolic augmentation of aortic pressure and systolic reduction of left ventricular afterload, resulting in hemodynamic benefits through increased coronary perfusion pressure and improved myocardial oxygen balance in patients with myocardial ischemia. Major trials have failed to conclusively demonstrate improvements in morbidity and mortality with counterpulsation therapy for patients with acute myocardial infarction (MI), cardiogenic shock, and/or severe coronary artery disease undergoing revascularization therapy, and the debate over its applications continues. Part I of this review focuses on the history of the development of counterpulsation, technical considerations, and complications associated with its use, its physiologic effects, and evidence for its use in myocardial ischemia and cardiogenic shock.

BACKGROUND: Whether revascularization should be performed as multivessel intervention at the time of index procedure (MV-index), staged procedure (MV-staged), or culprit only intervention (COI) in patients with multivessel disease (MVD) presenting with acute coronary syndrome (ACS) is unclear. We performed a systematic review and network meta-analysis of randomized controlled trials to assess the optimal revascularization strategy in this patient population. METHODS: PubMed, Embase, and Cochrane Central databases were systematically searched to identify all relevant studies. The outcomes assessed were major cardiac adverse events (MACE), all-cause mortality, cardiovascular mortality, myocardial infarction (MI), and revascularization. A Bayesian random-effects network meta-analysis was used to calculate odds ratio (OR) with credible interval (CrI). RESULTS: Thirteen studies with 8,066 patients were included in the analysis. There was a decreased risk of MACE (MV-index vs. COI: OR, 0.35; 95% CrI, 0.23-0.55; MV-staged vs COI: OR, 0.52; 95% CrI, 0.31-0.81) and revascularization (MV-index vs. COI: OR, 0.27; 95% CrI, 0.15-0.49; MV-staged vs. COI: OR, 0.38; 95% CrI, 0.19-0.70) with MV-index intervention and MV-staged intervention compared with COI. However, MV-index intervention and not MV-staged intervention was associated with a decreased risk of MI (MV-index vs. COI: OR, 0.35; 95% CrI, 0.12-0.93; MV-staged vs. COI: OR, 0.65; 95% CrI, 0.24-1.59) compared with COI. CONCLUSIONS: Our analysis suggests that multivessel intervention either at index procedure or as staged intervention may be more efficacious compared to COI in patients with MVD presenting with ACS.
