RESUMO
BACKGROUND: Optimal management strategy for patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease (MVD) still remains unclear, especially in the elderly population. The aim of this study was to assess long-term outcomes and predictors of morbi-mortality according to age in patients with a STEMI and MVD. METHODS: We prospectively included 381 consecutive patients with a STEMI who underwent primary angioplasty and showed MVD in the angiogram. 111 (29.1%) patients were older than 75 (≥75) years and 270 (70.9%) were younger than 75 (<75) years. The co-primary outcomes were the incidence of all-cause mortality and major adverse cardiac events (MACE) during follow-up. RESULTS: During a median follow-up of 22 months, patients ≥75 years showed a higher incidence of all-cause mortality and MACE, as compared to younger patients. On multivariate analysis, incomplete revascularization (IR) was only an independent predictor of MACE (HR = 3.1, CI 95%:1.9-4.7; P = .02) in younger patients; whereas in the elderly group severely depressed ejection fraction was the unique independent predictor of MACE (HR = 2.7, CI 95%:1.5-4.8; P = .001). IR was not associated with the risk of all-cause mortality in any group. CONCLUSION: This study confirms the relevant prevalence of MVD in STEMI patients, as well as the difference in outcomes of an IR strategy between both age-groups, being only independently associated with MACE in younger patients. This finding supports that a routine complete revascularization (CR) strategy seems to be the best therapeutic option in younguer patients, whereas in the elderly population may not confer a clear clinical benefit during a long-term follow-up.

OBJECTIVE: The aim of this case report is to highlight the importance of excluding aortic coarctation in a patient with a bicuspid aortic valve. CLINICAL PRESENTATION AND INTERVENTION: A 56-year-old woman with hypertension was admitted complaining of progressive dyspnea. Transthoracic echocardiography showed a calcified, bicuspid aortic valve with severe stenosis. Aortography revealed the presence of severe narrowing of the aorta between the carotid and subclavian arteries. The patient was referred for cardiovascular surgery in which successful aortic valve replacement and aortic correction were performed. CONCLUSION: This case report shows an uncommon finding of infantile aortic coarctation in an adult patient admitted with heart failure.

OBJECTIVE: The aim of this case report was to highlight the importance of ruling out pheochromocytoma in a patient with Von Hippel-Lindau disease (VHL) and cardiovascular manifestations. CLINICAL PRESENTATION AND INTERVENTION: A 22-year-old woman with type IIb VHL presented with signs and symptoms of acute decompensated heart failure. Transthoracic echocardiography showed a dilated left ventricle with severely depressed ejection fraction, confirmed by MRI. Urinary catecholamine and metanephrine tests had elevated levels and an abdominal MRI showed the presence of two cystic masses at the left hypochondrium. Surgical resection of both masses was performed, confirming the diagnosis of pheochromocytoma and clear cell renal carcinoma on histology. Six-month echocardiography showed a left ventricle with normal diameters and preserved ejection fraction. Genetic analysis revealed a germline mutation (exon 3 deletion of VHL). As there was no family history of VHL, it was determined to be a de novo mutation. CONCLUSION: This case report showed an atypical manifestation in a patient with VHL and underlines the importance of screening for pheochromocytoma in such patients.

OBJECTIVE: To highlight the usefulness of apixaban on intra-atrial thrombus that develops after previous treatment with warfarin. CLINICAL PRESENTATION AND INTERVENTION: A 69-year-old woman with a history of atrial fibrillation treated with warfarin presented with acute decompensated heart failure due to an episode of atrial fibrillation. Transesophageal echocardiogram revealed the presence of an intra-atrial thrombus. She was treated with apixaban, and transesophageal echocardiogram showed complete resolution of the thrombus after 3 weeks of treatment. CONCLUSION: This case highlights the usefulness of apixaban in the management of atrial fibrillation and proven intra-atrial thrombus.

BACKGROUND: Tricuspid regurgitation (TR) is a common echocardiographic finding that has been related to adverse outcome under various clinical scenarios. Nevertheless, evidence supporting its prognostic value in heart failure (HF) is scarce, and, in most cases, contradictory. We evaluated the association of TR grade with 1-year all-cause mortality in acute HF (AHF). METHODSâANDâRESULTS: We included 1,842 consecutive patients admitted for AHF. Mean age was 72.8±11.3 years, 51% were female and 45.5% had LVEF <50%. The severity of TR was graded in non-TR, mild (1), moderate (2), moderate-severe (3) and severe (4). At 1-year follow-up, 370 patients (20.1%) had died. In patients with LVEF ≥50%, a significant and positive association between TR severity and mortality was noted. Indeed, the HR for mortality for TR 3 and 4 vs. no TR/TR 1 were as follows: hazard ratios (HR), 1.68; 95% confidence intervals (95% CI): 1.08-2.60, P=0.02; and HR, 2.87; 95% CI: 1.61-5.09, P<0.001, respectively. In contrast, no association between TR grade and mortality (P=0.650) was observed in patients with LVEF <50% (P-value for interaction=0.033). CONCLUSIONS: A differential prognostic effect of TR severity on 1-year mortality was observed for LVEF HF status. The association was significant only in patients with LVEF ≥50%, with increasing mortality risk as TR became more severe.

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. TRIAL REGISTRATION: ClinicalTrials.gov number: NCT04743154.

Lipoprotein(a) (Lp[a]) is an emerging risk factor for incident ischemic heart disease. However, its role in risk stratification in in-hospital survivors to an index acute myocardial infarction (AMI) is scarcer, especially for predicting the risk of long-term recurrent AMI. We aimed to assess the relation between Lp(a) and very long-term recurrent AMI after an index episode of AMI. It is a retrospective analysis that included 1,223 consecutive patients with an AMI discharged from October 2000 to June 2003 in a single-teaching center. Lp(a) was assessed during index admission in all cases. The relation between Lp(a) at discharge and total recurrent AMI was evaluated through negative binomial regression. The mean age of the patients was 67.0 ± 12.3 years, 379 (31.0%) were women, and 394 (32.2%) were diabetic. The index event was more frequently non-ST-segment elevation myocardial infarction (66.0%). The median Lp(a) was 28.8 (11.8 to 63.4) mg/100 ml. During a median follow-up of 9.9 (4.6 to 15.5) years, 813 (66.6%) deaths and 1,205 AMI in 532 patients (43.5%) occurred. Lp(a) values were not associated with an increased risk of long-term all-cause mortality (p = 0.934). However, they were positively and nonlinearly associated with an increased risk of total long-term reinfarction (p = 0.016). In the subgroup analysis, there was no evidence of a differential effect for the most prevalent subgroups. In conclusion, after an AMI, elevated Lp(a) values assessed during hospitalization were associated with an increased risk of recurrent reinfarction in the very long term. Further prospective studies are warranted to evaluate their clinical implications.

INTRODUCTION AND OBJECTIVES: Carbohydrate antigen 125 (CA125), a biomarker associated with fluid overload, has proven useful in managing diuretic therapy in heart failure. We aimed to evaluate the impact of diuretic optimization guided by CA125 before transcatheter aortic valve implantation (TAVI) on outcomes. METHODS: This prospective interventional study enrolled patients scheduled for TAVI, in whom baseline CA125 was measured 2 weeks before TAVI. Patients with CA125 ≥ 20 U/mL underwent diuretic up-titration before TAVI. Three groups were included: group I) baseline CA125 <20 U/mL; IIa) CA125 ≥ 20 U/mL that decreased after treatment, and IIb) CA125 ≥ 20 U/mL that did not decrease. The primary outcome was changes in the Kansas City Cardiomyopathy Questionnaire at 3 and 12 months. The secondary endpoint was clinical events. RESULTS: The study included 184 patients (115 group I, 46 IIa, and 23 IIb). Groups I and IIa exhibited early and sustained improvements in the Kansas City Cardiomyopathy Questionnaire (group I: 18.9 points [95%CI, 15.7-22.1; P <.001] at 90 days, and 18.1 [95%CI, 14.9-21.4, P <.001] at 1 year; group IIa: 21.1 points [95%CI, 15.4-26.7; P <.001] and 19.5 [95%CI, 13.9-25.1; P <.001] respectively). In contrast, in group IIb there was no significant improvement at 90 days (P=.12), with improvement being significant only at 1 year (17.8 points, 95%CI, 5.9-29.6; P=.003). Over a median follow-up of 20.7 months, there were 63 (27.83%) deaths or heart failure admissions. Multivariate analysis showed a lower risk of events in group I vs IIb (HR, 0.28; 95%CI, 0.14-0.58; P <.001), and IIa vs IIb (HR, 0.24; 95%CI, 0.11-0.55; P <.001). CONCLUSIONS: Patients with persistently high CA125 despite diuretic therapy pre-TAVI showed slower functional recovery and poorer clinical outcomes after TAVI.
RESUMO
AIMS: There is limited information on the sex-specific longitudinal changes of left ventricular ejection fraction (LVEF) after an acute heart failure (AHF) hospitalization. We aimed to investigate whether LVEF trajectories over time and their impact on mortality and AHF readmission rates differ between men and women. METHODS AND RESULTS: We conducted a retrospective sex-specific analysis of longitudinal LVEF measurements (n = 9581) in 3383 patients with an index hospitalization for AHF in a single tertiary-level hospital. Statistical techniques suited for longitudinal data analysis were used. The mean age of the sample was 73.8 ± 11.2 years, and 47.9% were women. The mean LVEF was 49.4 ± 15.3%. At a median follow-up of 2.58 years (interquartile range 0.77-5.62), we registered 2197 deaths (64.9%) and 2597 AHF readmissions in 1302 (38.5%) patients. The longitudinal analysis showed that women had consistently higher LVEF values throughout the follow-up with both trajectories characterized by an early peak-approximately at 1 year-followed by decreasing values in men but a plateau in women. Multivariate between-sex comparisons across LVEF categories revealed that women had lower rates of AHF readmissions when LVEF ≤40%. On the contrary, women displayed an excess risk of AHF readmissions when LVEF >60%. A trend in the same direction was found for cardiovascular and all-cause mortality. CONCLUSION: Sex was a significant factor in determining the follow-up trajectory of LVEF and predicting differences in outcomes after an AHF admission. The findings suggest that women have a higher risk of AHF readmissions at higher LVEF values, while men have a higher risk at lower LVEF values. For all-cause and cardiovascular mortality, the same direction of the association was inferred but they were not significant.

INTRODUCTION AND OBJECTIVES: Catheter-directed therapy (CDT) for acute pulmonary embolism (PE) is an emerging therapy that combines heterogeneous techniques. The aim of the study was to provide a nationwide contemporary snapshot of clinical practice and CDT-related outcomes. METHODS: This Investigator-initiated multicenter registry aimed to include consecutive patients with intermediate-high risk (IHR) or high-risk (HR), acute PE eligible for CDT. The primary outcome of the study was in-hospital all-cause death. RESULTS: A total of 253 patients were included, of whom 93 (36.8%) had HR-PE, and 160 (63.2%) had IHR-PE with a mean age of 62.3±15.1 years. Local thrombolysis was performed in 70.8% and aspiration thrombectomy in 51.8%, with 23.3% of patients receiving both. However, aspiration thrombectomy was favored in the HR-PE cohort (80.6% vs 35%; P<.001). Only 51 patients (20.2%) underwent CDT with specific PE devices. The success rate for CDT was 90.9% (98.1% of IHR-PE patients vs 78.5% of HR-PE patients, P<.001). In-hospital mortality was 15.5%, and was highly concentrated in the HR-PE patients (37.6%) and significantly lower in IHR-PE patients (2.5%), P<.001. Long-term (24-month) mortality was 40.2% in HR-PE patients vs 8.2% in IHR-PE patients (P<.001). CONCLUSIONS: Despite the high success rate for CDT, in-hospital mortality in HR-PE is still high (37.6%) compared with very low IHR-PE mortality (2.5%).

INTRODUCTION: The benefit of complete revascularization (CR) on long-term total event reduction in patients with ST-segment elevation myocardial infarction (STEMI) and multivessel disease (MVD), still remains unclear. We assessed the efficacy of three different revascularization strategies on long-term total recurrent events. METHODS: We retrospectively analyzed 414 consecutive patients admitted with STEMI and MVD who were categorized according to the revascularization strategy used: culprit-vessel-only percutaneous coronary intervention (PCI) (n=163); in-hospital CR (n=136); and delayed CR (n=115). The combined endpoint assessed was all-cause mortality, the total number of myocardial infarctions, ischemia-driven revascularizations or strokes. Negative binomial regression was used to assess the association between the revascularization strategy and total events; risk estimates were expressed as an incidence rates ratio (IRR). RESULTS: At a median follow-up of four years (1.2-6), rates of the combined endpoint per 10 patient-years were 18, 0.8, and 0.6 in culprit-vessel-only PCI, in-hospital CR, and delayed CR strategies, respectively (p<0.001). After multivariable adjustment and when compared with culprit-vessel-only PCI, both in-hospital and delayed CR strategies were significantly associated with a reduction in the combined endpoint (IRR=0.40: 95% confidence interval (CI), 0.25-0.64; p<0.001; and IRR 0.40: 95% CI, 0.24-0.62; p<0.001, respectively). No differences were observed across in-hospital and delayed CR strategies. CONCLUSIONS: Complete revascularization of non-culprit lesions in patients with STEMI and MVD reduces the risk of total recurrent events during long-term follow-up. No differences between in-hospital and delayed CR strategies were found.

Revascularization of chronic total occlusions (CTO) is currently one of the most complex procedures in percutaneous coronary intervention (PCI), requiring the use of specific devices and a high level of experience to obtain good results. Once the clinical indication for extensive ischemia or angina uncontrolled with medical treatment has been established, the decision to perform coronary intervention is not simple, since this procedure has a higher rate of complications than non-PCI percutaneous intervention, higher ionizing radiation doses and a lower success rate. However, CTO revascularization has been shown to be helpful in symptomatic improvement of angina, reduction of ischemic burden, or improvement of ejection fraction. The aim of this work is to determine whether a model developed using deep learning techniques, and trained with angiography images, can better predict the likelihood of a successful revascularization procedure for a patient with a chronic total occlusion (CTO) lesion in their coronary artery (measured as procedure success and the duration of time during which X-ray imaging technology is used to perform a medical procedure) than the scales traditionally used. As a preliminary approach, patients with right coronary artery CTO will be included since they present standard angiographic projections that are performed in all patients and present less technical variability (duration, projection angle, image similarity) among them.The ultimate objective is to develop a predictive model to help the clinician in the decision to intervene and to analyze the performance in terms of predicting the success of the technique for the revascularization of chronic occlusions.Clinical Relevance- The development of a deep learning model based on the angiography images could potentially overcome the gold standard and help interventional cardiologists in the treatment decision for percutaneous coronary intervention, maximizing the success rate of coronary intervention.

Cardiovascular diseases (CVD) are the leading cause of death globally, being the heart valve complications one of the five most common heart problems. The aim of this study is the development of a MATLAB-based software tool to obtain several measurements derived from the aortic annulus for the planning of transcatheter aortic valve replacement (TAVR). The proposed software tool utilizes computed tomography (CT) images to reconstruct a volume of the patient. This virtual volume is rotated to situate the images in the plane which cuts the most basal points of the three aortic valve cusps, namely the aortic annulus, and obtain the required measurements. Nevertheless, the computer-user interaction will be entirely based on 2-dimension techniques to reduce both the complexity of the app and the computational load. The program was validated in CT images of 10 subjects with diagnosed aortic stenosis. A comparison of the results with the measurements used in the real clinical practice showed no significant differences between both methods.Clinical Relevance- The resulting computer tool provides significant information about the diseased aortic valve. This will allow clinicians to select the right prosthetic heart valve. It represents a cheaper and less complex alternative to sophisticated software tools which are currently being used to plan the intervention.

A non-neglectable percentage of patients with non-ST elevation myocardial infarction (NSTEMI) show non-obstructive coronary arteries (MINOCA). Specific data in older patients are scarce. We aimed to identify the clinical predictors of MINOCA in older patients admitted for NSTEMI and to explore the long-term prognosis of MINOCA. This was a single-center, observational, consecutive cohort study of older (≥70 years) patients admitted for NSTEMI between 2010 and 2014 who underwent coronary angiography. Univariate and multivariate Cox regression were performed to analyze the association of variables with MINOCA and all-cause mortality and with major adverse cardiac events (MACE), defined as a combined endpoint of all-cause mortality and nonfatal myocardial infarction and a combined endpoint of cardiovascular mortality, nonfatal myocardial infarction, and unplanned revascularization. The registry included 324 patients (mean age 78.8 ± 5.4 years), of which 71 (21.9%) were diagnosed with MINOCA. Predictors of MINOCA were female sex, left bundle branch block, pacemaker rhythm, chest pain at rest, peak troponin level, previous MI, Killip ≥2, and ST segment depression. Regarding prognosis, patients with obstructive coronary arteries (stenosis ≥50%) and the subgroup of MINOCA patients with plaques <50% had a similar prognosis; while MINOCA patients with angiographically smooth coronary arteries had a reduced risk of MACE. We conclude that the following: (1) in elderly patients admitted for NSTEMI, certain universally available clinical, electrocardiographic, and analytical variables are associated with the diagnosis of MINOCA; (2) elderly patients with MINOCA have a better prognosis than those with obstructive coronary arteries; however, only those with angiographically smooth coronary arteries have a reduced risk of all-cause mortality and MACE.

RESUMO
We aimed to assess the association between CA125 and the long-term risk of total acute heart failure (AHF) admissions in patients with an index hospitalization with AHF and preserved ejection fraction (HFpEF). We prospectively included 2369 patients between 2008 and 2019 in three centers. CA125 and NT-proBNP were measured during early hospitalization and evaluated as continuous and categorized in quartiles (Q). Negative binomial regressions were used to assess the association with the risk of recurrent AHF admission. The mean age of the sample patients was 76.7 ± 9.5 years and 1443 (60.9%) were women. Median values of CA125 and NT-proBNP were 38.3 (19.0-90.0) U/mL, and 2924 (1590-5447) pg/mL, respectively. During a median follow-up of 2.2 (0.8-4.6) years, 1200 (50.6%) patients died, and 2084 AHF admissions occurred in 1029 (43.4%) patients. After a multivariate adjustment, CA125, but not NT-proBNP, was positively and non-linearly associated with the risk of cumulative AHF-readmission (p < 0.001). Compared to Q1, patients belonging to Q2, Q3, and Q4 showed a stepwise risk increase (IRR = 1.29, 95% CI 1.08-1.55, p = 0.006; IRR = 1.35, 95% CI 1.12-1.63, p = 0.002; and IRR = 1.62, 95% CI 01.34-1.96, p < 0.001, respectively). In conclusion, CA125 predicted the risk of long-term AHF-readmission burden in patients with HFpEF and a recent admission for AHF.

BACKGROUND: Spontaneous coronary artery dissection (SCAD) is a rare but increasingly recognized cause of acute coronary syndrome. Many patients with SCAD have associated coronary risk factors. However, the implications of arterial hypertension in SCAD patients remain unknown. OBJECTIVE: This study sought to assess the clinical implications of arterial hypertension in a nationwide cohort of patients with SCAD. METHODS: The Spanish SCAD registry (NCT03607981) prospectively enrolled 318 consecutive patients. All coronary angiograms were centrally analyzed to confirm the diagnosis of SCAD. Patients were classified according to the presence of arterial hypertension. RESULTS: One-hundred eighteen patients (37%) had a diagnosis of arterial hypertension. Hypertensive SCAD patients were older (60 ± 12 vs. 51 ± 9 years old) and had more frequently dyslipidemia (56 vs. 23%) and diabetes (9 vs. 3%) but were less frequently smokers (15 vs. 35%) than normotensive SCAD patients (all P < 0.05). Most patients in both groups were female (90 vs. 87%, NS) and female patients with hypertension were more frequently postmenopausal (70 vs. 47%, P < 0.05). Hypertensive SCAD patients had more severe lesions and more frequently multivessel involvement (15 vs. 7%, P < 0.05) and coronary ectasia (19 vs. 7%, P < 0.05) but showed a similar prevalence of coronary tortuosity (34 vs. 26%, NS). Revascularization requirement was similar in both groups (17 vs. 26%, NS) but procedural success was significantly lower (65 vs. 88%, P < 0.05) and procedural-related complications more frequent (65 vs. 41%, P < 0.05) in SCAD patients with hypertension. CONCLUSION: Patients with SCAD and hypertension are older, more frequently postmenopausal and have more coronary risk factors than normotensive SCAD patients. During revascularization SCAD patients with hypertension obtain poorer results and have a higher risk of procedural-related complications (NCT03607981).

BACKGROUND: The Watchman FLX is a device upgrade of the Watchman 2.5 that incorporates several design enhancements intended to simplify left atrial appendage occlusion (LAAO) and improve procedural outcomes. This study compares peri-procedural results of LAAO with Watchman FLX (Boston Scientific, Marlborough, Massachusetts) in centers with varying degrees of experience with the Watchman 2.5 and Watchman FLX. METHODS: Prospective, multicenter, "real-world" registry including consecutive patients undergoing LAAO with the Watchman FLX at 26 Spanish sites (FLX-SPA registry). Implanting centers were classified according to the center's prior experience with the Watchman 2.5. A further division of centers according to whether or not they had performed ≤ 10 or > 10Watchman FLX implants was prespecified at the beginning of the study. Procedural outcomes of institutions stratified according to their experience with the Watchman 2.5 and FLX devices were compared. RESULTS: 359 patients [mean age 75.5 (SD8.1), CHA2DS2-VASc 4.4 (SD1.4), HAS-BLED 3.8(SD0.9)] were included. Global success rate was 98.6%, successful LAAO with the first selected device size was achieved in 95.5% patients and the device was implanted at first attempt in 78.6% cases. There were only 9(2.5%) major peri-procedural complications. No differences in efficacy or safety results according to the centers previous experience with Watchman 2.5 and procedural volume with Watchman FLX existed. CONCLUSIONS: The Watchman FLX attains high procedural success rates with complete LAA sealing in unselected, real-world patients, along with a low incidence of peri-procedural complications, regardless of operators experience with its previous device iteration or the number of Watchman FLX devices implanted.
RESUMO
Pulmonary vascular resistance (PVR) is a marker of pulmonary vascular remodeling. A non-invasive model assessed by cardiovascular magnetic resonance (CMR) has been proposed to estimate PVR. However, its accuracy has not yet been evaluated in patients with heart failure. We prospectively included 108 patients admitted with acute heart failure (AHF), in whom a right heart catheterization (RHC) and CMR were performed at the same day. PVR was estimated by CMR applying the model: PVR = 19.38 - [4.62 × Ln pulmonary artery average velocity (in cm/s)] - [0.08 × right ventricle ejection fraction (in %)], and by RHC using standard formulae. The median age of the cohort was 67 years (interquartile range 58-73), and 34% were females. The median of PVR assessed by RHC and CMR were 2.2 WU (1.5-4) and 5 WU (3.4-7), respectively. We found a weak correlation between invasive PVR and PVR assessed by CMR (Spearman r = 0.21, p = 0.02). The area under the ROC curve for PVR assessed by CMR to detect PVR ≥ 3 WU was 0.57, 95% confidence interval (CI): 0.47-0.68. In patients with AHF, the non-invasive estimation of PVR using CMR shows poor accuracy, as well as a limited capacity to discriminate increased PVR values.

INTRODUCTION AND OBJECTIVES: Discordant data have been reported on the prognosis of myocardial infarction with nonobstructive coronary arteries (MINOCA). Moreover, few data are available on the impact of angiographic subtypes. The objectives of this study were to assess the prognostic impact on the long-term follow-up of the diagnosis of MINOCA and its angiographic subtypes. METHODS: We included 591 consecutive patients with non-ST-segment elevation myocardial infarction (NSTEMI) who underwent coronary angiography. MINOCA was classified according to angiographic findings as smooth coronary arteries, mild irregularities (< 30% stenosis), and moderate atherosclerosis (30%-49% stenosis). The primary endpoint was a composite of mortality, nonfatal myocardial infarction, and revascularization (MACE) at a median of 5 years of follow-up. RESULTS: A total of 121 patients (20.5%) showed no obstructive lesions. MINOCA was associated with a lower occurrence of MACE (P=.014; HR, 0.63; 95%CI, 0.44-0.91) and was confirmed as an independent factor in the multivariate analysis (P=.018; HR, 0.63; 95%CI, 0.43-0.92). On analysis of the separate components of the main endpoint, MINOCA was significantly associated with a lower rate of myocardial infarction and revascularization, but not with mortality. Analysis of angiographic subtypes among MINOCA patients showed that smooth coronary arteries were a statistically significant protective factor on both univariate and multivariate analysis, while mild irregularities and 30% to 49% plaques were associated with a higher risk of MACE. CONCLUSIONS: MINOCA is associated with a lower rate of MACE, driven by fewer reinfarctions and revascularizations. Within the angiographic subtypes of MINOCA, smooth arteries were independently associated with a lower number of MACE.
