Objective: Several studies have demonstrated an association between frailty and worse outcomes in patients with acute coronary syndrome (ACS); however, there is a lack of evidence from Colombia. This study aims to evaluate the association between frailty and the risk of adverse outcomes in patients over 65 years old diagnosed with ACS., Materials and Methods: A prospective cohort study was conducted, including patients over 65 years old who underwent coronary angiography due to an ACS diagnosis at a hospital in Medellín, Colombia. Frailty was assessed using the FRAIL scale. The primary outcome was all-cause mortality at 30 days. Secondary outcomes included length of hospital stay and a composite outcome of in-hospital or 30-day mortality, contrast-induced nephropathy (CIN), acute heart failure, cardiogenic shock, hemorrhagic complications, and vascular complications., Results: A total of 112 patients were included. Frail patients (n=35, 31.3%) were older, had a lower socioeconomic status, higher GRACE scores, and more severely compromised coronary vessels. A significant association was observed between frailty and 30-day mortality (relative risk [RR] 19.00, 95% confidence interval [CI]: 5.04-72.61; p<0.001), the composite outcome (RR 4.57, 95% CI: 2.56-8.34; p<0.001), and longer hospital stays (9 days vs. 5 days in the non-frail group)., Conclusions: A considerable number of patients over 65 years old with ACS were frail. Frailty was associated with adverse in-hospital and 30-day outcomes., Competing Interests: Conflictos de interés: Ninguno

Objetive: Congenital heart diseases (CHD) can be found in pregnant women. Although cardiac interventions in the catheterization laboratory are considered safe and effective, it is preferable to wait 3-6 months after delivery to correct simple, uncomplicated CHD; however, this may result in follow-up losses. The objective is to present our experience in correcting CHD during the early puerperium (EP)., Materials and Methods: All cases of pregnant women with CHD, including atrial septal defect (ASD), patent ductus arteriosus (PDA), and aortic coarctation (CoA) between 2017-2023, who underwent percutaneous defect correction during the EP were collected., Results: Fifteen pregnant women were included, diagnosed with ASD (5), PDA (6), and CoA (4). Five patients (33.3%) were classified as WHO risk class IV; the procedure was successful in 80% of the cases, and only 1 patient presented complications., Conclusions: In our experience, the closure of uncomplicated congenital defects during the EP did not present major complications and could be a treatment strategy to prevent follow-up losses after delivery in pregnant women with CHD., Competing Interests: Conflictos de interés: Ninguno

Introduction: Radial arterial access is one of the main ways to perform left heart catheterization and coronary angiography in different clinical settings, due to its lower rate of local complications and similar clinical results to when using the femoral access., Objective: To determine the incidence of complications of radial access in interventional cardiology procedures of a hemodynamic service, as well as the impact on functionality and predictive factors for presentation., Methodology: Prospective observational cohort-type study in patients undergoing radial access coronary angiography in a university hospital with collection of demographic, clinical and ultrasound data prior to the procedure and 24 hours after it; The statistical model of logistic regression was applied to evaluate the association between the variables and the complications., Results: 100 patients were obtained, 62% men, with a mean age of 64 years, 69% had arterial hypertension, 38% diabetes mellitus, 35% dyslipidemia, 2% peripheral arterial disease, and 10% chronic kidney disease. The reason for coronary angiography was non-ST-segment elevation acute coronary syndrome (NSTE-ACS) 65%, ST-segment elevation myocardial infarction (STEMI) 28%, pre-surgical 6%, and chronic coronary syndrome 1%. A 6 Fr introducer was used in all of them. 13% complications were documented, the most common being arterial occlusion and hematoma. Only one had implications for the functionality of the hand after a complication. After multivariate regression, height (<1.65 m) and dynamometry (<25 pounds) were found as predictive factors by area under the curve analysis using the Youden index., Conclusion: The present cohort had an incidence of complications detected by ultrasound of 13%, although none of these had direct clinical implications and only one reported alteration in functionality. Height less than 1.65 m and dynamometry less than 25 pounds were found as predictive factors.

Background and Objective: Chronic thromboembolic pulmonary hypertension (CTEPH) has a dismal prognosis when there are no central pulmonary thrombi amenable to surgical thromboendarterectomy. Pulmonary vasodilators could be useful in this setting. Initial experience with bosentan in a small group of patients with CTEPH has shown favourable results on the short term (3 to 6 months), but long-term effects remain unknown., Patients and Method: We retrospectively describe the effects of bosentan in 6 CTEPH patients with a mean follow-up period of 15 months (range, 8-26)., Results: At 3-month follow-up, all patients had experienced clinical improvement, with a statistical trend towards reduced pulmonary vascular resistance [1,008 (624) dyn/sec/cm-5 versus 768 (392), p = 0.07]. Clinical improvement persisted on the long-term, [baseline NYHA functional class 3.0 (0.4) versus 2.0 (0) at the last follow-up visit, p < 0.01]. Six-minute walk-test results [baseline 230 (124) meters versus a 313 (70) at 1 year] and NTproBNP [2,225 (2,079) pg/ml versus a 1,056 (1,104) at 1 year] were also consistent with persistent beneficial effect., Conclusions: Bosentan seemed to provide long-term benefits in this small series of patients with CTEPH.
