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.

RESUMO

BACKGROUND: Coronary obstruction (CO) following transcatheter aortic valve replacement (TAVR) is a life-threatening complication, scarcely studied. OBJECTIVES: The authors analyzed the incidence of CO after TAVR, presentation, management, and in-hospital and 1-year clinical outcomes in a large series of patients undergoing TAVR. METHODS: Patients from the Spanish TAVI (Transcatheter Aortic Valve Implantation) registry who presented with CO in the procedure, during hospitalization or at follow-up were included. Computed tomography (CT) risk factors were assessed. In-hospital, 30-day, and 1-year all-cause mortality rates were analyzed and compared with patients without CO using logistic regression models in the overall cohort and in a propensity score-matched cohort. RESULTS: Of 13,675 patients undergoing TAVR, 115 (0.80%) presented with a CO, mainly during the procedure (83.5%). The incidence of CO was stable throughout the study period (2009-2021), with a median annual rate of 0.8% (range 0.3%-1.3%). Preimplantation CT scans were available in 105 patients (91.3%). A combination of at least 2 CT-based risk factors was less frequent in native than in valve-in-valve patients (31.7% vs 78.3%; P < 0.01). Percutaneous coronary intervention was the treatment of choice in 100 patients (86.9%), with a technical success of 78.0%. In-hospital, 30-day, and 1-year mortality rates were higher in CO patients than in those without CO (37.4% vs 4.1%, 38.3% vs 4.3%, and 39.1% vs 9.1%, respectively; P < 0.001). CONCLUSIONS: In this large, nationwide TAVR registry, CO was a rare, but often fatal, complication that did not decrease over time. The lack of identifiable predisposing factors in a subset of patients and the frequently challenging treatment when established may partly explain these findings.

RESUMO

BACKGROUND: Predictors of antiplatelet therapy discontinuation (ATD) during the first year after drug-eluting stent implantation are poorly known. METHODS AND RESULTS: This was a prospective study with 3-, 6-, 9-, and 12-month follow-up of patients receiving at least 1 drug-eluting stent between January and April 2008 in 29 hospitals. Individual- and hospital-level predictors of ATD were assessed by hierarchical-multinomial regression analysis. ATD could be assessed in 1622 candidates for follow-up (82.5%). A total of 234 patients (14.4%) interrupted at least 1 antiplatelet therapy drug, predominantly clopidogrel (n=182, 11.8%). Bleeding events or invasive procedures led to ATD in 109 patients. This was predicted by renal impairment (odds ratio [OR] 2.81, 95% confidence interval [CI] 1.48 to 5.34), prior major hemorrhage (OR 3.77, 95% CI 1.41 to 10.03), and peripheral arterial disease (OR 1.78, 95% CI 1.01 to 3.15). Medical decisions led to ATD in 70 patients; this was predicted by long-term use of anticoagulant therapy (OR 3.88, 95% CI 1.26 to 11.98), undergoing the procedure in a private hospital (OR 13.3, 95% CI 1.69 to 105), and not receiving instructions about medication (OR 2.8, 95% CI 1.23 to 6.36). Thirty-nine patients interrupted ATD on their own initiative, mainly immigrants (OR 3.78, 95% CI 1.2 to 11.98) and consumers of psychotropic drugs (OR 2.58, 95% CI 1.3 to 5.12). CONCLUSIONS: ATD during the first year after drug-eluting stent implantation is based mainly on patient decision or a medical decision not associated with major bleeding events or major surgical procedures. Individual- and hospital-level variables are important to predict ATD.

RESUMO

INTRODUCTION: Erectile dysfunction (ED) is associated with cardiovascular disease (CVD) because it is highly prevalent among those with cardiovascular risk factors (CVRFs). Moreover, it precedes the development of CVD and is considered a subrogate marker of subclinical CVD. AIM: The aim of this study was to evaluate the presence of ED among patients with type 2 diabetes (DM2) without macroangiopathy, and to assess the association between ED and other CVRFs, chronic diabetes complications, silent myocardial ischemia (SMI), and peripheral arterial disease (PAD). METHODS: One hundred fifty-four male patients with DM2 and without clinical evidence of CVD were included in the study. The presence of ED, PAD, SMI, chronic diabetic complications, and other CVRFs was evaluated in these patients. MAIN OUTCOME MEASURES: PAD; SMI; ED; 24-hour blood pressure Holter; lipid profile; insulin resistance; testosterone; chronic inflammation; nephropathy; retinopathy; neuropathy. RESULTS: Prevalence of ED was 68.2%. Patients with ED were older and characterized by DM2, systolic blood pressure (BP), retinopathy, and insulin treatment of longer duration than patients without ED, even when adjusting for age was performed. Adjusting for duration of diabetic condition revealed significant differences in age and systolic BP. Independent factors for ED were age (57.7±7.5 years, relative risks [RR 1.1], P=0.003) and duration of diabetes (9[3-15] years, RR 1.1, P=0.006). SMI was detected in 13.6% of patients (18.1% in patients with ED vs. 4.1% in patients without ED). Asymptomatic PAD was detected in 13.2% of subjects (14.4% in patients with ED vs. 10.4% in patients without). CONCLUSIONS: ED is highly prevalent in DM2, and is associated with the presence of SMI, higher systolic BP and chronic microvascular diabetic complications.

RESUMO

Silent myocardial ischemia occurs more frequently in diabetics. Differential arterial pulse pressure is a valuable predictor of cardiovascular disease. We studied 48 consecutive male patients with type-2 diabetes and no known history of ischemic heart disease. Ambulatory monitoring of arterial pressure was carried out and the presence of silent myocardial ischemia was studied using a protocol that involved: resting ECG, echocardiography, 24-hour Holter ECG, conventional exercise stress testing, and exercise testing with nuclear scanning. Nine patients (19%) had silent myocardial ischemia. Differential pulse pressure had good discriminative ability in identifying the presence of silent ischemia: the area under the receiver operating characteristic (ROC) curve was 0.83 (95% confidence interval [CI], 0.71-0.96; P=.002). This predictive ability was also observed on adjusted logistic regression modeling (odds ratio [OR], 1.24, 95% CI = 1.02-1.49). We found that the OR for the risk of silent ischemia for every 10-mmHg increase in differential pulse pressure was 8.5 (95% CI 1.7-31.2). Age and differential pulse pressure were the only independent predictors of silent myocardial ischemia found in this study.
