RESUMEN
AIMS: Severe mitral regurgitation (MR) following acute myocardial infarction (MI) is associated with high mortality rates and has inconclusive recommendations in clinical guidelines. We aimed to report the international experience of patients with secondary MR following acute MI and compare the outcomes of those treated conservatively, surgically, and percutaneously. METHODS AND RESULTS: Retrospective international registry of consecutive patients with at least moderate-to-severe MR following MI treated in 21 centres in North America, Europe, and the Middle East. The registry included patients treated conservatively and those having surgical mitral valve repair or replacement (SMVR) or percutaneous mitral valve repair (PMVR) using edge-to-edge repair. The primary endpoint was in-hospital mortality. A total of 471 patients were included (43% female, age 73 ± 11 years): 205 underwent interventions, of whom 106 were SMVR and 99 PMVR. Patients who underwent mitral valve intervention were in a worse clinical state (Killip class ≥3 in 60% vs. 43%, P < 0.01), but yet had lower in-hospital and 1-year mortality compared with those treated conservatively [11% vs. 27%, P < 0.01 and 16% vs. 35%, P < 0.01; adjusted hazard ratio (HR) 0.28, 95% confidence interval (CI) 0.18-0.46, P < 0.01]. Surgical mitral valve repair or replacement was performed earlier than PMVR [median of 12 days from MI date (interquartile range 5-19) vs. 19 days (10-40), P < 0.01]. The immediate procedural success did not differ between SMVR and PMVR (92% vs. 93%, P = 0.53). However, in-hospital and 1-year mortality rates were significantly higher in SMVR than in PMVR (16% vs. 6%, P = 0.03 and 31% vs. 17%, P = 0.04; adjusted HR 3.75, 95% CI 1.55-9.07, P < 0.01). CONCLUSIONS: Early intervention may mitigate the poor prognosis associated with conservative therapy in patients with post-MI MR. Percutaneous mitral valve repair can serve as an alternative for surgery in reducing MR for high-risk patients.

OBJECTIVES: The aim of this analysis was to assess the effect of the coronary revascularization strategy during index admission on clinical outcomes among patients undergoing percutaneous coronary intervention (PCI) with multivessel coronary artery disease (MVD). BACKGROUND: The value of complete revascularization (CR) over incomplete revascularization (IR) in MVD patients is not fully established. METHODS: Patients with MVD defined as ≥2 major epicardial vessels with ≥50% stenosis were selected from the observational all-comer e-Ultimaster registry. Patients were treated with a sirolimus-eluting thin-strut coronary stent. Completeness of revascularization was physician assessed at the index procedure or an eventually staged procedure during the index hospitalization. Outcomes measures at 1 year were target lesion failure (TLF) (composite of cardiac death, target vessel-related myocardial infarction [MI], and clinically driven target lesion revascularization [TLR]), and patient-oriented composite endpoint (POCE) (all-cause mortality, MI, or revascularization). The inverse probability of treatment weights (IPTW) methodology was used to perform a matched analysis. RESULTS: The registry recruited 37,198 patients of whom 15,441 (41.5%) had MVD. CR on hospital discharge was achieved in 7413 (48.0%) patients and IR in 8028 (52.0%) patients. Mean age was 64.6 ± 11.1 versus 65.7 ± 11.0 years (p < 0.01), male gender 77.9% and 77.3% (p = 0.41) and diabetes 31.3% versus 33.4% (p = 0.01) for CR and IR, respectively. Chronic stable angina patients more commonly underwent CR (47.6% vs. 36.8%, p < 0.01). After propensity weighted analysis, 90.5% of CR patients were angina-free at 1 year compared with 87.5% of IR patients (p < 0.01). TLF (3.3% vs. 4.4%; p < 0.01), POCE (6.8% vs. 10.8%; p < .01), and all-cause mortality (2.3% vs. 3.1%; p < .01) were all lower in CR patients. CONCLUSIONS: A physician-directed use of a CR strategy utilizing sirolimus-eluting thin-strut stent results in optimized clinical outcomes and less angina in an all-comer population. Our findings suggest that a CR should be aimed for.

Background: The main cause of acute coronary syndrome (ACS) is coronary artery obstruction due to atherosclerotic plaque growth or thrombus formation secondary to plaque rupture or erosion. However, there is a subgroup of patients with signs and symptoms suggestive of ACS but without relevant coronary artery obstruction on coronary angiography. This population is defined as myocardial infarction with non-obstructive coronary arteries (MINOCA). The present study analyzes the clinical features and outcomes of very young patients with a diagnosis of MINOCA. Method: Nested case-control study of ≤40-year-old patients referred for coronary angiography due to clinical suspicion of ACS. Patients were divided into three groups: patients with obstructive coronary artery disease (CAD), patients diagnosed with MINOCA, and controls with non-coronary artery disease. Results: Of 19,321 coronary angiographies performed in our center in a period of 10 years, 408 (2.1%) were in patients ≤40 years old, and MINOCA was identified in 32 (21%) patients. The cardiovascular risk factors for obstructive CAD and MINOCA were very similar. The incidence of major adverse cardiovascular events (MACE) at follow-up was significantly higher in the MINOCA (HR 4.13 (95%CI 1.22-13.89) and obstructive CAD (HR 4.59 (95%CI 1.90-10.99) patients compared to controls. Cocaine use HR 14.58 (95%CI 3.08-69.02), family history of CAD HR 6.20 (95%CI 1.40-27.43), and depression HR 5.16 (95%CI 1.06-25.24) were associated with a poor outcome in the MINOCA population. Conclusion: Very young patients with MINOCA had a poor prognosis at long-term follow-up, similar to patients with obstructive CAD. Focusing efforts on secondary prevention is essential in this population.

OBJECTIVES: To assess outcomes in patients with acute mitral regurgitation (MR) following acute myocardial infarction (AMI) who received percutaneous mitral valve repair (PMVR) with the MitraClip device and to compare outcomes of patients who developed cardiogenic shock (CS) to those who did not (non-CS). BACKGROUND: Acute MR after AMI may lead to CS and is associated with high mortality. METHODS: This registry analyzed patients with MR after AMI who were treated with MitraClip at 18 centers within eight countries between January 2016 and February 2020. Patients were stratified into CS and non-CS groups. Primary outcomes were mortality and rehospitalization due to heart failure. Secondary outcomes were acute procedural success, functional improvement, and MR reduction. Multivariable Cox regression analysis evaluated association of CS with clinical outcomes. RESULTS: Among 93 patients analyzed (age 70.3 ± 10.2 years), 50 patients (53.8%) experienced CS before PMVR. Mortality at 30 days (10% CS vs. 2.3% non-CS; p = .212) did not differ between groups. After median follow-up of 7 months (IQR 2.5-17 months), the combined event mortality/re-hospitalization was similar (28% CS vs. 25.6% non-CS; p = .793). Likewise, immediate procedural success (90% CS vs. 93% non-CS; p = .793) and need for reintervention (CS 6% vs. non-CS 2.3%, p = .621) or re-admission due to HF (CS 13% vs. NCS 23%, p = .253) at 3 months did not differ. CS was not independently associated with the combined end-point (hazard ratio 1.1; 95% CI, 0.3-4.6; p = .889). CONCLUSIONS: Patients found to have significant MR during their index hospitalization for AMI had similar clinical outcomes with PMVR whether they presented in or out of cardiogenic shock, provided initial hemodynamic stabilization was first achieved before PMVR.

ABSTRACT: The aim of our study is to assess the impact of anemia, chronic kidney disease, and diabetes mellitus on platelet reactivity (PR) in patients with severe aortic stenosis, both at baseline and after transcatheter aortic valve implantation (TAVI). This study is a prespecified subanalysis of the REAC-TAVI prospective, multicenter trial that included patients pretreated with aspirin + clopidogrel before TAVI. PR was measured at baseline and at 5 different time points after TAVI with the VerifyNow assay (Accriva Diagnostics, San Diego, CA), over a 3-month follow-up period. Patients with high PR (HPR) at baseline, before TAVI (n = 48) were randomized to aspirin + clopidogrel or aspirin + ticagrelor for 3 months, whereas those with normal PR (NPR) (n = 20) were continued on aspirin + clopidogrel. A "raiser response" in PR was defined as an increase in PR units >20% of baseline after TAVI. Patients with HPR before TAVI presented concomitant anemia and chronic kidney disease more frequently than their counterparts with NPR. Anemia and higher body mass index were independently associated with HPR to clopidogrel at baseline. Moreover, anemic patients with baseline HPR who were continued on clopidogrel presented higher PR after TAVI than patients with HPR switched to ticagrelor. All patients with baseline NPR presented a "raiser response" after TAVI, which was nonexistent among patients with HPR managed with ticagrelor. In summary, anemia seems as a relevant factor associated with baseline HPR and higher PR after TAVI in patients with baseline HPR randomized to clopidogrel, whereas ticagrelor proved more effective than clopidogrel at attaining sustained reductions in PR during follow-up, regardless of baseline comorbidities.

Purpose. Echocardiography assessment from apical five-chamber view (A5CV) is the standard technique for aortic stenosis (AS) grading. Data on non-apical views, such as right parasternal (RPV), subcostal (SCV) and suprasternal notch (SSNV), is scarce and constitutes the aim of our study. Methods. We designed an observational study that included patients with AS recruited prospectively in whom the stenosis was graded by echocardiography from A5CV and non-apical view. The value of non-apical views in up-grading the stenosis severity (primary objective), the prognostic relevance of such reclassification and the feasibility and reproducibility of non-apical views assessment (secondary objectives) was evaluated. Results. Feasibility of AS appraisal from RPV, SCV and SSNV was 78%, 81% and 56%, respectively (SCV vs SSNV, p = .009). AS were up-graded from non-apical views according to peak gradient, mean gradient, area and indexed area by 24%, 17%, 24% and 22%, respectively (p < .0001). Non-apical views reclassified from non-severe to severe AS, from low gradient severe to high gradient severe AS and from non-critical to critical AS 19%, 23% and 3% of cases (p < .0001). The 4-years hard cardiac events rate was 41% in patients with non-severe AS, 67% in patients with severe AS from non-apical views, 68% in patients with severe AS from A5CV and 80% in patients with severe AS from A5CV and non-apical views (p < .001). Reproducibility of AS evaluation from non-apical views was fair to excellent (intraclass correlation coefficients: SSNV = 0.44, RPV = 0.61, SCV = 0.92). Conclusion. Assessment of AS from non-apical views is feasible, reproducible and valuable over A5CV; its use is encouraged.

BACKGROUND: Leadless pacemakers (L-PM) are an emerging effective and safe technology that offer an alternative to conventional pacemakers (C-PM) for right ventricular stimulation. However, there is little information about their potential benefits for quality of life (QoL) in patients with L-PM. We compared QoL between patients with L-PM and C-PM. METHODS: The study population comprised patients undergoing single chamber pacemaker implantation from December 2016 to March 2018. The SF-36 questionnaire was used to evaluate QoL at baseline and at 6 months of followup. We also used a questionnaire consisted of 10 specific questions related to the implant procedure. RESULTS: A total of 106 patients (64 C-PM; 42 L-PM) were included. There were no differences in baseline characteristics between the groups (C-PM vs L-PM), except for age (81.5 vs 77.3 years; P = .012) and diabetes (38% vs 17%; P = .021). Baseline SF-36 scores did not differ between the groups. At 6 months followup, patients in the L-PM group scored significantly higher on physical function (63 vs 42; P < .001), physical role (64 vs 36; P = .004), and mental health (75 vs 65; P = .017), even after adjusting for covariates. Pacemaker-related discomfort and physical restrictions were significantly lower for the L-PM group. CONCLUSION: L-PM is associated with better QoL than C-PM in both physical and mental health. Patients undergoing L-PM implantation reported less procedure-related discomfort, physical restriction, and preoccupation.

AIMS: Nutrition is an important determinant of health above the age of 80 years. Malnutrition in the elderly is often underdiagnosed. The aim of this study was to report the prevalence and prognostic value of malnutrition in patients ≥80 years old with atrial fibrillation (AF) with and without anticoagulant therapy. METHODS AND RESULTS: We assessed the nutritional status of 4724 octogenarian patients with diagnoses of AF in a single centre from Spain between 2014 and 2017 with the CONUT score. Malnutrition was confirmed in 2036 patients (43.1%). Anticoagulation prescription was more frequent in patients with good nutrition than in those malnourished (79.5% vs. 71.7%, P < 0.001). The impact of malnutrition on mortality was evaluated by Cox regression, whereas its association with ischaemic stroke and major bleeding was studied through competing risk analysis. After multivariate adjusting, malnutrition was associated with mortality [hazard ratio (HR) 1.36, 95% confidence interval (CI) 1.24-1.49], stroke [sub-distribution HR (sHR) 1.37, 95% CI 1.10-1.69], and major bleeding (sHR 1.29, 95% CI 1.02-1.64). In anticoagulated patients, the embolic-haemorrhagic trade-off event was virtually neutral for those who had normal nutritional status [average daily rates (ADRs) for stroke and bleeding: 4.70 and 4.69 per 100 000 patients/day, respectively; difference = +0.01 per 100 000 patients/day; P = 0.99] and negative for those with malnutrition (ADR for stroke and bleeding: 5.38 and 7.61 per 100 000 patients/day, respectively; difference = -2.23 per 100 000 patients/day; P = 0.07). CONCLUSION: Malnutrition is very common in octogenarian patients with AF, being a clinical predictor for poor prognosis. For anticoagulated patients, malnutrition was associated with a negative embolic-haemorrhagic balance.

BACKGROUND: Pre-clinical results of a novel open-cell, thin strut, durable polymer, laser cut cobalt chromium sirolimus-eluting stent (Angiolite) were promising. Using quantitative optical coherence tomographic (OCT) analyses, we explored the healing characteristics of the Angiolite DES system at 3- and 6-months post implantation. METHODS: A total of 103 patients with de novo coronary lesions underwent percutaneous coronary intervention with the Angiolite DES and were randomized 1:3 into two cohorts for angiographic and OCT follow-up, with 28 and 70 patients returning for 3- or 6-month post-PCI surveillance, respectively. The primary endpoints were the 6-month rates of OCT-derived neointimal proliferation, strut coverage and incomplete strut apposition (ISA), whilst the secondary endpoints were 3-month OCT-derived measures of strut coverage and ISA, as well as 6-month quantitative coronary angiographic-derived measures [late lumen loss (LLL), binary restenosis]. RESULTS: The Angiolite stent was successfully implanted in all patients, without periprocedural complications. At 3- and 6-months follow-up, OCT strut coverage was evident in 86.3% and 83.3% of struts, mean neointimal thickness was 73.7 ± 46.5 µm and 73.9 ± 54.3 µm, mean neo-intimal area obstruction of 5.8% ±10.3% and 4.4% ± 11.3%, and ISA rates were 1.3% ± 7.3% and 1.1% ± 6.2%, respectively. In-stent LLL at 6 months was 0.07 ± 0.37 mm, with a binary in-stent angiographic restenosis rate of 0% without any stent thrombosis, myocardial infarction or cardiovascular death, with 1 patient undergoing ischemia-driven target-lesion revascularization. CONCLUSIONS: At 6 months, the Angiolite DES was safe with high rates of strut coverage, modest degrees of neointimal hyperplasia and very low rates of strut malapposition. These data coupled with the absence of in-stent binary restenosis and a very low 6-month in-stent LLL point towards an efficacious DES. Future studies are required to evaluate its efficacy in broader lesion subsets with longer follow-up.

AIM: The aim of this study was to establish safety and efficacy of a new sirolimus-eluting stent with bioresorbable polymer, Ultimaster (BP-SES). Sirolimus-eluting stent with bioresorbable polymer was compared with everolimus-eluting, permanent polymer, Xience stent (PP-EES) in the frame of a CENTURY II clinical trial designed to make global clinical data compliant with regulatory requirements in Europe and Japan. METHODS AND RESULTS: The CENTURY II is a prospective, multicentre, randomized (1 : 1), single blind, controlled, non-inferiority clinical trial conducted at 58 study sites in Japan, Europe, and Korea. A total of 1123 patients requiring a percutaneous coronary intervention (PCI) procedure, with implantation of drug-eluting stent (DES), were enrolled [total population (TP)]. Randomization of patients was stratified for the subset of patients matching requirements for DES in Japan (Cohort JR, n = 722). Baseline patient demographic and angiographic characteristics were similar in both study arms, with minimal differences between the TP and Cohort JR. The primary endpoint, freedom from target lesion failure (TLF) at 9 months-TLF [composite of cardiac death, target-vessel-related myocardial infarction (MI) and target lesion revascularization]-was 95.6% with BP-SES and 95.1% with PP-EES (Pnon-inferiority<0.0001). Composite of cardiac death and MI rate was 2.9 and 3.8% (P = 0.40) and target vessel revascularization was 4.5% with BP-SES and 4.2% with PP-EES (P = 0.77). The stent thrombosis rate was 0.9% in both arms. In Cohort JR, freedom from TLF was 95.9 and 94.6% (Pnon-inferiority < 0.0005) with BP-SES and PP-EES, respectively. CONCLUSION: The new bioresorbable polymer sirolimus-eluting stent showed safety and efficacy profiles similar to durable polymer everolimus-eluting stent at 9-month follow-up. STUDY REGISTRATION NUMBER: UMIN000006940.

BACKGROUND: The present study analyzes a cohort of consecutive patients with ST-segment elevation acute myocardial infarction (STEMI), evaluating the ischemia-reperfusion times from the perspective of gender differences (females versus males), with a long-term follow-up. METHODS: Single-center analytical cohort study of patients with STEMI in a tertiary hospital, between January 2015 and December 2020. RESULTS: A total of 2668 patients were included, 2002 (75%) men and 666 (25%) women. The time elapsed from the onset of symptoms to the opening of the artery was 197min (IQR 140-300) vs 220min (IQR 152-340), p=0.004 in men and women respectively. A delay in health care significantly impacts the occurrence of cardiovascular adverse events at follow-up, HR 1.34 [95%CI 1.06-1.70]; p=0.015. CONCLUSIONS: Women took longer to go to health care services and had a longer delay both in the diagnosis of STEMI and in coronary reperfusion. It is imperative to emphasize the necessity of educating women about the recognition of ischemic heart disease symptoms, empowering them to raise early alarms and seek timely medical attention.

BACKGROUND: Diabetes mellitus (DM) increases the probability of presenting atrial fibrillation (AF) and it is a predictor of its ischemic stroke. There is limited information of the association between glycated hemoglobin (HbA1c) levels and ischemic, embolic or bleeding events in patients with pre-DM and AF. METHODS: To investigate whether the presence of pre-DM in patients with AF predicts ischemic or bleeding events, myocardial infarction or mortality, we performed a retrospective study with a final cohort of 2993 non-diabetic patients with AF and data of glycated hemoglobin (HbA1c). We divided the cohort in two groups: those with normal glucose (n = 1351) and those with pre-diabetes (n = 1642). Incidence rates were calculated as the number of events per 100 person-years and were then compared between groups. Competitive hazard regression analysis for non-fatal events(death as the competing event) and conventional Cox regression for mortality were performed. RESULTS: There was not difference between groups for incidence rates of the different events per 100 person-years. Even considering HbA1c as continuous variable, the unadjusted analysis showed no relation between levels of HbA1c and more risk of events. This association remained not significant after adjustment for CHA2DS2-VASc score, HAS-BLED score and anticoagulation therapy. CONCLUSION: In this study of 2993 non-diabetic patients with new-onset AF, we have not found an association between HbA1c and worse prognosis when it is in the range of pre-diabetes.

BACKGROUND AND AIMS: Liver diseases play an important role in the development and progression of atrial fibrillation (AF). The Fibrosis-4 (FIB-4) index is a non-invasive score recommended for detecting liver fibrosis. Since the association between liver fibrosis and outcomes of AF patients is still not well defined, we aim to analyze prognosis impact of FIB-4 index in those patients. METHODS: A retrospective population-based cohort study was performed with 12,870 unselected patients from a single health area in Spain with AF from 2014 to 2019. Cox regression models were used to estimate the association of FIB-4 index with mortality. The association with ischemic stroke (IS), major bleeding (MB), acute myocardial infarction (AMI), and heart failure (HF) was assessed by competing risk analysis. RESULTS: A total of 61.1%, 22.0%, and 16.9% were classified as low, moderate and high risk of liver fibrosis according to FIB-4 index, respectively. During a mean follow-up of 4.5 ± 1.7 years, FIB-4 index was associated with mortality (adjusted HR 1.04; 95% CI 1.01-1.06; p = 0.002), MB and HF (adjusted sHR 1.03, 95% CI 1.01-1.04; p = 0.004), but not with IS or with AMI. The association between FIB-4 and MB was only found in patients treated with vitamin K antagonists, not in patients on direct oral anticoagulants. CONCLUSIONS: The FIB-4 index, a non-invasive scoring method for evaluating liver fibrosis, is independently associated with all-cause mortality, MB and HF in patients with AF, suggesting that it may be useful as a risk assessment tool to identify adverse outcomes in patients with AF.

Aortic stenosis (AS) is the most prevalent degenerative valvular disease in western countries. Transthoracic echocardiography (TTE) is considered, nowadays, to be the main imaging technique for the work-up of AS due to high availability, safety, low cost, and excellent capacity to evaluate aortic valve (AV) morphology and function. Despite the diagnosis of AS being considered straightforward for a very long time, based on high gradients and reduced aortic valve area (AVA), many patients with AS represent a real dilemma for cardiologist. On the one hand, the acoustic window may be inadequate and the TTE limited in some cases. On the other hand, a growing body of evidence shows that patients with low gradients (due to systolic dysfunction, concentric hypertrophy or coexistence of another valve disease such as mitral stenosis or regurgitation) may develop severe AS (low-flow low-gradient severe AS) with a similar or even worse prognosis. The use of complementary imaging techniques such as transesophageal echocardiography (TEE), multidetector computed tomography (MDTC), or cardiac magnetic resonance (CMR) plays a key role in such scenarios. The aim of this review is to summarize the diagnostic challenges associated with patients with AS and the advantages of a comprehensive multimodality cardiac imaging (MCI) approach to reach a precise grading of the disease, a crucial factor to warrant an adequate management of patients.
RESUMEN
BACKGROUND: Rate control is the most commonly employed first-line management strategy for atrial fibrillation (AF) in patients with chronic kidney disease (CKD). Principal agents used to control heart rate (HR) include beta-blockers (BB) and nondihydropyridine calcium channel blockers (ND-CCB). However, there is a paucity of published studies of the differences between those drugs in CKD patients. HYPOTHESIS: The present study aimed to investigate the differences, in terms of hospitalizations due to a poor HR control, in patients with AF under a rate-control strategy according to glomerular filtration rate (GFR). METHODS: The study cohort included 2804 AF patients under rate-control regime (BB or ND-CCB) between January 2014 and April 2020. The end point, determined by competing risk regression, was hospitalizations for AF with rapid ventricular response (RVR), slow ventricular response (SVR), and need for pacemaker. RESULTS: On multivariate analysis, there were no statistical differences between ND-CCB and BB for subjects with GFR > 60 mL/min/1.73 m2 (subdistribution heart rate [sHR] 0.850, 95% confidence interval [CI]: 0.61-1.19; p = .442) and GFR 30-59 mL/min/1.73 m2 (sHR 1.242, 95% CI: 0.80-1.63; p = .333), while in patients with GFR < 30 mL/min/1.73 m2, ND-CCB therapy was associated with increased hospitalizations due to poor HR control (sHR 4.53, 95% CI: 1.19-17.18; p = .026). CONCLUSION: In patients with GFR ≥ 30 mL/min/1.73 m2, the choice of ND-CCB or BB had no impact on hospitalizations due to poor HR control, while in GFR < 30 mL/min/1.73 m2, a possible association was detected. The effects of these drugs on GFR < 30 mL/min/1.73 m2 would require further investigation.

BACKGROUND: The FIRE trial (Functional Assessment in Elderly Myocardial Infarction Patients With Multivessel Disease) enrolled 1445 older (aged ≥75 years) patients with myocardial infarction and multivessel disease in Italy, Spain, and Poland. Patients were randomized to physiology-guided complete revascularization or treatment of the only culprit lesion. Physiology-guided complete revascularization significantly reduced ischemic adverse events at 1 year. This prespecified analysis investigated the changes between the 2 study groups in angina status, quality of life, physical performance, and frailty. METHODS: Patients underwent validated scales at hospital discharge (baseline) and 1 year later. Angina status was evaluated using the Seattle Angina Questionnaire, health-related quality of life by EQ visual analog scale, physical performance by short physical performance battery, and frailty by the clinical frailty scale. Mixed models for repeated measures analysis were used to study the association between the treatment arms, time, and scales. RESULTS: Baseline and 1-year Seattle Angina Questionnaire, EQ visual analog scale, short physical performance battery, and clinical frailty scale were collected in around two-thirds of the entire FIRE study population. The mean age was 80.9±4.6 years (female sex, 35.9%). Overall, 35.3% were admitted for ST-segment-elevation myocardial infarction, whereas the others were admitted for non-ST-segment-elevation myocardial infarction. Physiology-guided complete revascularization, compared with culprit-only revascularization, was associated with greater improvement in terms of angina status (Seattle Angina Questionnaire summary score, 7.3 [95% CI, 6.1-8.6] points), health-related quality of life (EQ visual analog scale, 6.2 [95% CI, 4.4-8.1] points), and physical performance (short physical performance battery, 1.1 [95% CI, 0.9-1.3] points). After 1 year, patients randomized to culprit-only revascularization experienced a deterioration in frailty status (clinical frailty scale, 0.2 [95% CI, 0.1-0.3] points), which was not observed in patients randomized to physiology-guided complete revascularization. CONCLUSIONS: The present analysis suggested that a physiology-guided complete revascularization is associated with consistent benefits in terms of angina status, quality of life, physical performance, and the absence of further deterioration of the frailty status.
