Clinical Outcomes After Acute Coronary Syndromes or Revascularization Among People Living With HIV: A Systematic Review and Meta-Analysis.

Importance: Clinical outcomes after acute coronary syndromes (ACS) or percutaneous coronary interventions (PCIs) in people living with HIV have not been characterized in sufficient detail, and extant data have not been synthesized adequately. Objective: To better characterize clinical outcomes and postdischarge treatment of patients living with HIV after ACS or PCIs compared with patients in an HIV-negative control group. Data Sources: Ovid MEDLINE, Embase, and Web of Science were searched for all available longitudinal studies of patients living with HIV after ACS or PCIs from inception until August 2023. Study Selection: Included studies met the following criteria: patients living with HIV and HIV-negative comparator group included, patients presenting with ACS or undergoing PCI included, and longitudinal follow-up data collected after the initial event. Data Extraction and Synthesis: Data extraction was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. Clinical outcome data were pooled using a random-effects model meta-analysis. Main Outcome and Measures: The following clinical outcomes were studied: all-cause mortality, major adverse cardiovascular events, cardiovascular death, recurrent ACS, stroke, new heart failure, total lesion revascularization, and total vessel revascularization. The maximally adjusted relative risk (RR) of clinical outcomes on follow-up comparing patients living with HIV with patients in control groups was taken as the main outcome measure. Results: A total of 15 studies including 9499 patients living with HIV (pooled proportion [range], 76.4% [64.3%-100%] male; pooled mean [range] age, 56.2 [47.0-63.0] years) and 1 531 117 patients without HIV in a control group (pooled proportion [range], 61.7% [59.7%-100%] male; pooled mean [range] age, 67.7 [42.0-69.4] years) were included; both populations were predominantly male, but patients living with HIV were younger by approximately 11 years. Patients living with HIV were also significantly more likely to be current smokers (pooled proportion [range], 59.1% [24.0%-75.0%] smokers vs 42.8% [26.0%-64.1%] smokers) and engage in illicit drug use (pooled proportion [range], 31.2% [2.0%-33.7%] drug use vs 6.8% [0%-11.5%] drug use) and had higher triglyceride (pooled mean [range], 233 [167-268] vs 171 [148-220] mg/dL) and lower high-density lipoprotein-cholesterol (pooled mean [range], 40 [26-43] vs 46 [29-46] mg/dL) levels. Populations with and without HIV were followed up for a pooled mean (range) of 16.2 (3.0-60.8) months and 11.9 (3.0-60.8) months, respectively. On postdischarge follow-up, patients living with HIV had lower prevalence of statin (pooled proportion [range], 53.3% [45.8%-96.1%] vs 59.9% [58.4%-99.0%]) and ß-blocker (pooled proportion [range], 54.0% [51.3%-90.0%] vs 60.6% [59.6%-93.6%]) prescriptions compared with those in the control group, but these differences were not statistically significant. There was a significantly increased risk among patients living with HIV vs those without HIV for all-cause mortality (RR, 1.64; 95% CI, 1.32-2.04), major adverse cardiovascular events (RR, 1.11; 95% CI, 1.01-1.22), recurrent ACS (RR, 1.83; 95% CI, 1.12-2.97), and admissions for new heart failure (RR, 3.39; 95% CI, 1.73-6.62). Conclusions and Relevance: These findings suggest the need for attention toward secondary prevention strategies to address poor outcomes of cardiovascular disease among patients living with HIV.

In-hospital versus after-discharge complete revascularization in patients with ST segment elevation myocardial infarction and multivessel disease. REVIVA-ST trial.

INTRODUCTION: Complete revascularization (CR) in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease (MVD), is associated with a reduction in major adverse cardiovascular events (MACE). However, there is uncertainty about whether nonculprit-lesion revascularization should be performed, during index hospitalization or delayed, especially regarding health care resources utilization. In this study, we aimed to evaluate the impact of in-hospital nonculprit-lesion revascularization vs. delayed (after discharge) revascularization on the length of index hospitalization. METHODS: In this single-center study, we randomly assigned patients with STEMI and MVD who underwent successful culprit-lesion PCI to a strategy of either CR during in-hospital admission or a delayed CR after discharge. The first primary endpoint was the length of hospital stay. The second endpoint was the composite of cardiovascular death, myocardial infarction or ischemia-driven revascularization at 12 months (MACE). RESULTS: From January 2018 to December 2022, we enrolled 258 patients (131 allocated to CR during in-hospital admission and 127 to an after-discharge CR). We found a significant reduction in the length of hospital stay in those assigned to after-discharge CR strategy [4 days (3-5) versus 7 days (5-9); p = 0.001]. At 12-month of follow-up, no differences were found in the occurrence of MACE, 7 (5.34%) patients in in-hospital CR and 4 (3.15%) in after-discharge CR strategy; (hazard ratio, 0.59; 95% confidence interval, 0.17 to 2.02; p = 0.397). CONCLUSIONS: In STEMI patients with MVD, an after-discharge CR strategy reduces the length of index hospitalization without an increased risk of MACE after 12 months of follow-up.

Complete versus culprit-only revascularization for older adults with acute coronary syndromes: a meta-analysis and systematic review

BACKGROUND: Randomized studies support complete over culprit-only revascularization for patients with acute coronary syndrome (ACS) However,whether these findings extend to elderly patients has not been thoroughly explored. METHODS: We conducted a systematic review and meta-analysis comparing clinical outcomes of elderly individuals (defined as age > 75 years) with ACS and multivessel coronary artery disease submitted to complete vs. culprit-only percutaneous coronary intervention (PCI). PubMed, Embase, and Cochrane were searched. We computed pooled hazard ratios (HRs) with 95% confidence intervals (CI) to preserve time-to-event data RESULTS: We included 7 studies, of which 2 were randomized controlled trials (RCTs), comprising 7,409 patients, of whom 3225 (43.5%) underwent complete revascularization. As compared with culprit lesion only PCI, complete revascularization was associated with a lower risk of all-cause mortality (HR 0.76; 95% CI 0.68-0.85; p<0.001), cardiovascular mortality (HR 0.67; 95% CI 0.54-0.82; p<0.001), and recurrent myocardial infarction (MI) (HR 0.65; 95% CI 0.50-0.85; p=0.002). There was no significant difference between the groups regarding the risk of recurrent revascularizations (HR 0.79; 95% CI 0.54-1.16; p=0.23). CONCLUSION: Among elderly patients with ACS and multivessel CAD, complete revascularization is associated with a lower risk of all-cause mortality, cardiovascular mortality, and recurrent MI.

FFR-Guided Complete or Culprit-Only PCI in Patients with Myocardial Infarction.

BACKGROUND: The benefit of fractional flow reserve (FFR)-guided complete revascularization in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel coronary artery disease remains unclear. METHODS: In this multinational, registry-based, randomized trial, we assigned patients with STEMI or very-high-risk non-STEMI (NSTEMI) and multivessel disease who were undergoing primary percutaneous coronary intervention (PCI) of the culprit lesion to receive either FFR-guided complete revascularization of nonculprit lesions or no further revascularization. The primary outcome was a composite of death from any cause, myocardial infarction, or unplanned revascularization. The two key secondary outcomes were a composite of death from any cause or myocardial infarction and unplanned revascularization. RESULTS: A total of 1542 patients underwent randomization, with 764 assigned to receive FFR-guided complete revascularization and 778 assigned to receive culprit-lesion-only PCI. At a median follow-up of 4.8 years (interquartile range, 4.3 to 5.2), a primary-outcome event had occurred in 145 patients (19.0%) in the complete-revascularization group and in 159 patients (20.4%) in the culprit-lesion-only group (hazard ratio, 0.93; 95% confidence interval [CI], 0.74 to 1.17; P = 0.53). With respect to the secondary outcomes, no apparent between-group differences were observed in the composite of death from any cause or myocardial infarction (hazard ratio, 1.12; 95% CI, 0.87 to 1.44) or unplanned revascularization (hazard ratio, 0.76; 95% CI, 0.56 to 1.04). There were no apparent between-group differences in safety outcomes. CONCLUSIONS: Among patients with STEMI or very-high-risk NSTEMI and multivessel coronary artery disease, FFR-guided complete revascularization was not shown to result in a lower risk of a composite of death from any cause, myocardial infarction, or unplanned revascularization than culprit-lesion-only PCI at 4.8 years.

Outcomes by sex in the International Study of Comparative Health Effectiveness With Medical and Invasive Approaches (ISCHEMIA) trial.

BACKGROUND: In the International Study of Comparative Health Effectiveness With Medical and Invasive Approaches (ISCHEMIA) trial, among participants with stable coronary artery disease, the risk of cardiac events was similar between an invasive (INV) strategy of angiography and coronary revascularisation and a conservative (CON) strategy of initial medical therapy alone. Outcomes according to participant sex were not reported. AIMS: We aimed to analyse the outcomes of ISCHEMIA by participant sex. METHODS: We evaluated 1) the association between participant sex and the likelihood of undergoing revascularisation for participants randomised to the INV arm; 2) the risk of the ISCHEMIA primary composite outcome (cardiovascular death, any myocardial infarction [MI] or rehospitalisation for unstable angina, heart failure or resuscitated cardiac arrest) by participant sex; and 3) the contribution of the individual primary outcome components to the composite outcome by participant sex. RESULTS: Of 5,179 randomised participants, 1,168 (22.6%) were women. Female sex was independently associated with a lower likelihood of revascularisation when assigned to the INV arm (adjusted odds ratio 0.75, 95% confidence interval [CI]: 0.57-0.99; p=0.04). The INV versus CON effect on the primary composite outcome was similar between sexes (women: hazard ratio [HR] 0.96, 95% CI: 0.70-1.33; men: HR 0.90, 95% CI: 0.76-1.07; pinteraction=0.71). The contribution of the individual components to the composite outcome was similar between sexes except for procedural MI, which was significantly lower in women (9/151 [5.9%]) than men (67/519 [12.9%]; p=0.01). CONCLUSIONS: In ISCHEMIA, women assigned to the INV arm were less likely to undergo revascularisation than men. The effect of an INV versus CON strategy was consistent by sex, but women had a significantly lower contribution of procedural MI to the primary outcome.

[Functional status of patients after myocardial revascularization combined with chronic low back pain at the sanatorium-resort stage of medical rehabilitation]. / Funktsional'nyi status patsientov posle revaskulyarizatsii miokarda v sochetanii s khronicheskoi bol'yu v nizhnei chasti spiny na sanatorno-kurortnom etape meditsinskoi reabilitatsii.

Chronic ischemic heart disease (CIHD) is the leading cause of morbidity and mortality, increasing in proportion to the growth of the older population. Rehabilitative measures in patients who have undergone the myocardial revascularization, with back pain currently have insufficient evidence base. The differentiated program of medical rehabilitation (MR) at the stage of sanatorium-resort treatment is not regulated. A description of the comorbid patients' functional status will create a differentiated system of individual rehabilitation program set up. OBJECTIVE: To develop an algorithm for assessing the functional status of patients after myocardial revascularization with chronic low back pain. MATERIAL AND METHODS: The single-center cross-sectional cohort study (September 2021 - May 2022 yrs) included 50 patients after a myocardial revascularization with chronic low back pain (36 women, 14 men; median age 63.5 [55.5; 67.5] years), who were the study group and 10 patients with CIHD (5 women, 5 men; median age 65.0 [62.0; 68.0] years) who joined the control group. All patients underwent clinical (neurological and therapeutic examination), functional (clinical tests, echocardiography) and laboratory (general and biochemical blood analysis, blood cytokine levels) investigations, the functional class of impairment was defined. RESULTS: There are 4 groups with combined pain syndrome (cardiogenic and vertebrogenic) in different ratios due to different functional and laboratory status among patients after the myocardial revascularization with chronic back pain. The presence of cardiogenic pain syndrome was associated with an increase in leukocyte and peripheral blood glucose levels, interleukin-6, myocardial mass enlargement, while vertebrogenic pain syndrome correlated with personal anxiety. CONCLUSION: The evaluation of the functional status of patients according to the degree of severity of cardiogenic and vertebrogenic pain syndrome has revealed a simple method of pathogenetically based differentiation selection for individual rehabilitation program of patient development.

Examining the Outcomes of Hybrid Coronary Revascularization in Acute STEMI Patients from 2015 to 2022.

Background: The global rise of chronic diseases, especially cardiovascular disease (CVD), poses a significant public health challenge, being a leading cause of death and disability worldwide. In Iran, the surge in CVD incidence and its risk factors, along with a decrease in the age of onset, has notably increased the reliance on coronary artery bypass grafting (CABG) as a life-saving intervention. Staged hybrid coronary revascularization (HCR), which combines percutaneous coronary intervention with delayed CABG, offers a novel approach for patients with complex coronary artery disease, potentially improving survival and reducing complications. Considering the newness of this treatment method and the limitations of previous studies, we investigated the results of staged HCR in acute ST-elevation myocardial infarction (STEMI) patients in this study. Methods: This observational study was performed on consecutive patients with acute STEMI who underwent staged HCR and were referred to Valiasr and Razi hospitals in Birjand from 2015 to 2022. The required information (demographic information, angiography result, and operation side effects) was collected in a checklist. If necessary, the patients were contacted by phone. After collecting the data, they were entered into SPSS version 16 software. Results: This study was conducted on 33 patients with a mean age of 64.88 ± 9.24 years (69.7% male). The average hospital stay was 11.6 ± 8.9 days (3 to 72 days). The mean ejection fraction and syntax score were 36.5% ± 10.2% and 31.21 ± 6.7, respectively. Following surgery and during hospitalization, arrhythmias were observed, including 33.3% with premature ventricular contractions, 18.1% with atrial fibrillation, and 3.1% with ventricular tachycardia. The average number of pack cells (red blood cells that have been separated for blood transfusion) and creatinine changes before and after hybrid surgery were 640.9 ± 670.9 cc and 0.055 ± 0.07. In the follow-up, 9.09% of patients had late mortality, 6.1% of patients had urinary tract infections during hospitalization, 6.1% of patients had surgical site infections, 3.1% needed dialysis, and none of the studied patients had premature death or need for reintervention. Conclusions: The results of our study indicated that staged HCR performed early after an ACS is not associated with significant mortality or complications. Therefore, it is advisable to consider staged HCR as a surgical option in appropriate cases.

82-rubidium positron emission tomography determined myocardial flow reserve and outcomes following cardiac revascularisation - A multicentre registry study.

BACKGROUND: Finding patients with chronic coronary syndromes (CCS) whom revascularization could benefit, is complicated. Myocardial flow reserve (MFR), a measurement of myocardial perfusion, has proven prognostic value on survival and risk of major adverse cardiac events (MACE). We investigated if MFR identifies who may benefit from revascularization. METHODS: Among 7462 patients from Danish hospitals examined with 82Rb PET between January 2018 and August 2020, patients with ≥5% reversible perfusion defects were followed for MACE and all-cause mortality. Associations between revascularisation (within 90 days) and outcomes according to MFR (< and ≥ 2) was assessed by Cox regression adjusted by inverse probability weighting for demographics, cardiovascular risk factors, comorbidities, and 82Rb PET variables. RESULTS: Of 1806 patients with ≥5% reversible perfusion defect, 893 (49%) had MFR < 2 and 491 underwent revascularisation (36.6% in MFR < 2 versus 17.9% MFR ≥ 2, p < 0.001). During a median follow-up of 37.0 [31.0-45.8 IQR] months, 251 experienced a MACE and 173 died. Revascularisation was associated with lower adjusted risk of all-cause mortality (hazard ratio [HR], 0.51 [95% CI, 0.30-0.88], p = 0.015) and MACE (HR, 0.54 [0.33-0.87], p = 0.012) in patients with MFR < 2 but not MFR ≥ 2 for all-cause mortality (HR 1.33 [0.52-3.40], p = 0.542) and MACE (HR 1.50 [0.79-2.84], p = 0.211). MFR significantly modified the association between revascularisation and MACE, but not all-cause mortality (interaction p-value 0.021 and 0.094, respectively). CONCLUSIONS: Revascularization was associated with improved prognosis among patients with impaired MFR. No association was seen in patients with normal MFR. In patients with regional ischemia, MFR may identify patients with a prognostic benefit from revascularization.

Differences in coronary angiographic findings and outcomes between men and postmenopausal women with stable chest pain.

BACKGROUND: Despite the significant increase in cardiovascular events in women after menopause, studies comparing postmenopausal women and men are scarce. METHODS: We analyzed data from a nationwide, multicenter, prospective registry and enrolled 2412 patients with stable chest pain who underwent elective coronary angiography. Binary coronary artery disease (b-CAD) was defined as the ≥50% stenosis of epicardial coronary arteries, including the left main coronary artery. RESULTS: Compared with the men, postmenopausal women were older (66.6 ±â€…8.5 vs. 59.5 ±â€…11.4 years) and had higher high-density lipoprotein cholesterol levels (49.0 ±â€…12.8 vs. 43.6 ±â€…11.6 mg/dl, P  < 0.01). The prevalence of diabetes did not differ significantly ( P  = 0.40), and smoking was more common in men than in postmenopausal women ( P  ≤ 0.01). At enrollment, b-CAD and revascularization were more common in men than in postmenopausal women (50.3% vs. 41.0% and 14.4% vs. 9.7%, respectively; both P  < 0.01). However, multivariate analyses revealed that revascularization [odds ratio (OR): 0.72; 95% confidence interval (CI): 0.49-1.08] was not significantly related to sex and a similar result was found in age propensity-matched population (OR: 0.80; 95% CI: 0.52-1.24). During the follow-up period, the secondary composite cardiovascular outcomes were lower in postmenopausal women than in men (OR: 0.55; 95% CI: 0.31-0.98), also consistent with the result using the age propensity-mated population (OR: 0.33; 95% CI: 0.13-0.85). CONCLUSION: Postmenopausal women experienced coronary revascularization comparable to those in men at enrollment, despite the average age of postmenopausal women was 7 years older than that of men.Postmenopausal women exhibit better clinical outcomes than those of men if optimal treatment is provided.
