Risk stratification and lipid evaluation in mexican patients, evidence of lipid and cardiovascular analysis in REMECAR. The mexican registry of cardiovascular diseases (REMECAR group).

Background and aims: Dyslipidaemia is a significant risk factor for cardiovascular disease in the Mexican population. This analysis aimed to describe the baseline LDL-c levels of patients presenting to cardiovascular clinics and evaluate the proportion who achieved their risk-based LDL-c goals as recommended by 2021 ESC prevention guidelines. Methods: The REMECAR registry is an observational study of patients attending a specialized cardiovascular clinic for their first visit. The cardiovascular risk was retrospectively determined using the 2021 ESC guideline stratification and the SCORE2 and SCORE-OP. Results: A total of 5443 patients were included in the analysis. Within this population, 55.96% presented as very high, 39.98% as high and 4.06% as moderate to low risk. 63% of the participants were not on any lipid-lowering treatment at entry, while 12.4% were receiving high-intensity statin therapy. Patients presenting with established atherosclerotic cardiovascular disease had a mean LDL-c of 90.9 ± 40.7 mg/dL. Of these, 14.1% were achieving LDL-c levels of 70-55 mg/dL and 19.3% were achieving LDL-c levels <55 mg/dL. In diabetic patients at very high risk, only 25.7% achieved their LDL-c goal. Finally, in patients without another risk factor and very high-risk evaluated by SCORE2 & SCORE-OP, only 14% of patients achieved their LDL-c goals. Conclusions: An important number of patients were not receiving any lipid-lowering therapy. Furthermore, in those who were, a significant portion did not achieve LDL-c recommended thresholds. Our results underline the urgent need to improve the prescription and optimization of lipid-lowering therapy as the current management appears to be insufficient for achieving optimal recommended goals. Identifying key barriers in lipid management is fundamental to establishing better strategies and health system policies to reduce cardiovascular risk.

Gender differences and management of stroke risk of nonvalvular atrial fibrillation in an upper middle-income country: Insights from the CARMEN-AF registry.

BACKGROUND: Atrial Fibrillation (AF) is associated with an increased risk of stroke and systemic embolism. Several studies have suggested that female AF patients could have a greater risk for stroke. There is scarce information about clinical characteristics and use of antithrombotic therapies in Latin American patients with nonvalvular AF. OBJECTIVE: To describe the gender differences in clinical characteristics, thromboembolic risk, and antithrombotic therapy of patients with nonvalvular AF recruited in Mexico, an upper middle-income country, into the prospective national CARMEN-AF Registry. METHODS: A total of 1423 consecutive patients, with at least one thromboembolic risk factor were enrolled in CARMEN-AF Registry during a three-year period (2014-2017). They were categorized according to Gender. RESULTS: Overall, 48.6% were women, mean age 70 ±â€¯12 years. Diabetes, smoking, alcoholism, non-ischemic cardiomyopathy, coronary artery disease, and obstructive sleep apnea were higher in men. Most women were found with paroxysmal AF (40.6%), and most men with permanent AF (44.0%). No gender differences were found in the use of vitamin K antagonists (VKA) (30.5% in women vs. 28.0% in men). No gender differences were found in the use of direct oral anticoagulants (DOAC) (33.8% women vs 35.4% men). CONCLUSIONS: CARMEN-AF Registry demonstrates that in Mexico, regardless of gender, a large proportion of patients remain undertreated. No gender differences were found in the use of VKA or DOAC.

Treatment of seven patients with coarctation of the aorta treated using a Mexican-made platinum/iridium stent.

BACKGROUND: Nowadays, stenting is the treatment of choice in patients >15 years of age with coarctation of the aorta without hypoplastic aortic isthmus. The platinum/iridium stent manufactured in Mexico may be an affordable alternative with the same benefits as the imported stent. METHODS: This is a series of cases in which we present the immediate results of the first seven patients with coarctation of the aorta treated with the platinum/iridium stent manufactured in Mexico. The first four patients were selected and treated at the Cardiology Hospital of the National Medical Center during the year 2003, two more patients were selected and treated at the National Institute of Cardiology, and another patient was treated at the Military Hospital, Mexico City, in the year 2005. RESULTS: A total of seven patients were successfully treated with the platinum/iridium stent without any complications. Average initial gradient was 56.4 mmHg (range: 30-90 mmHg). In six patients, the final gradient was 0.0 mmHg and in one it was 2 mmHg. In the four patients treated in the Cardiology Hospital of the National Medical Center, mean follow-up time was 17.5 +/- 2.5 months, with a gradient of 0.0 mmHg. All patients are in NYHA Class I. At 12 months follow-up, the gradient remains as 0 mmHg and the patients are still in NYHA Class I functional state. CONCLUSIONS: This stent can be a safe and effective alternative to other stents available on the market for the treatment of coarctation of the aorta.
