NCT05542719
Background. Atherosclerotic cardiovascular disease (ACVD) comprising coronary disease, cerebrovascular disease, peripheral artery disease, and aortic atherosclerosis caused 8.9 million deaths worldwide according to reports submitted by the World Health Organization during 2019, the development and progression of atherosclerosis is favored in the presence of modifiable risk factors such as dyslipidemia. In Mexico, during the period from December 29, 2019, to August 29, 2020, 141,873 deaths from heart disease were reported, even above the 108,658 deaths from SARS COV2 in the same time period. Although it is known that the Mexican mestizo population is susceptible to certain metabolic lipid disorders related to genetic variants, the frequency of dyslipidemia in patients with high cardiovascular risk is unknown to date and may be responsible for this increase. On the other hand, it has been shown that lowering LDL-C levels in this population by means of the pharmacological or dietary treatment stated the current guidelines, decreases chance of death, heart failure, angina, re-infarction or need for coronary revascularization; however, there are still patients not achieving treatment goals. Consequently, it is suggested that through the implementation and correct use of technological tools it is possible to increase efficiency in the medical follow-up of patients, allowing for appropriate lipid levels, like other chronic degenerative diseases such as diabetes and systemic arterial hypertension. Objective. To describe the frequency of dyslipidemias in high-risk and very high-risk patients with atherosclerotic cardiovascular disease, who are IMSS beneficiaries, and to analyze the impact of using an application to achieve dyslipidemia treatment goals at one-year follow-up. Hypothesis For the National Register: Not required since the main objective is to carry out a national register of dyslipidemias. For the use of the application: Null hypothesis: The use of the application does not change the frequency of patients with high and extremely high atherosclerotic cardiovascular risk who achieve the goals of dyslipidemia treatment during one year of follow-up.
NCT05094284
Over the past three decades, coronary stent struts have been made progressively thinner. Thin strut drug-eluting stents (DES) performed better than their thicker counterparts in a recent study. Thinner struts discourage abnormal coronary flow after implantation and associated with greater flexibility, deliverability and better clinical outcomes. Lower strut thickness may be particularly advantageous in small target vessels because thicker struts and smaller minimum in-stent lumen diameter are independent predictors of in-stent restenosis. BioFreedom Ultra is a thin strut (84μm), cobalt-chromium, carrier-free drug-coated stent with Biolimus A9 drug. The BioFreedom Ultra stent is intended for percutaneous coronary intervention (PCI) for high-bleeding-risk (HBR) patients treated with 1-month dual antiplatelet therapy. BioFreedom Ultra received CE mark in October 2020 supported by the LEADERS FREE III trial which enrolled 400 HBR patients using the same inclusion criteria as the LEADERS FREE randomized trial. LEADERS FREE III is a single-arm trial, with all patients treated using the BioFreedom Ultra stent. The data was compared to the BioFreedom stainless steel drug-coated stent (DCS-StS) and bare-metal stent (BMS) groups from LEADERS FREE. The primary safety endpoint of the trial was a composite of cardiac death, myocardial infarction, or definite/probable stent thrombosis. The primary efficacy endpoint was clinically driven target lesion revascularization. The study found that the BioFreedom Ultra was non-inferior to the DCS-StS for safety and superior to the BMS for efficacy. Definite or probable stent thrombosis at 1 year in this HBR population was only 1%. Recently, the Biofreedom QCA randomized trial compared the Biofreedom Ultra with the stainless steel version (DCS-StS) in an all-comer population. In this prospective, single-blind non-inferiority randomized (1:1) trial, BioFreedom Ultra was non-inferiority for late lumen loss at 9 months in comparison with DCS-StS.
NCT02074527
Design: Observational - Cross study with followed up for 30 days. The Primary Objective is to realize a record that reflects a national overview of the role of cardiac catheterization in patients with congenital heart disease in hospitals distributed by geographic density of each region of Brazil.
NCT03667703
Infants with congenital heart disease often require an intervention during their first year of life. Infants are generally admitted to a cardiac intensive care unit and are routinely prescribed stress ulcer prophylaxis to decrease acid release from the stomach to prevent stress ulcer formation. However, these medicines may not be safe and could put infants at increased risk for hospital-acquired infections, necrotizing enterocolitis and alteration to the infant's microbiome. The investigators plan to assess the feasibility of conducting a prospective, blinded randomized control trial to determine the safety of withholding stress ulcer prophylaxis in critically ill infants with congenital heart disease. In addition, the investigators plan to examine the changes to the infant's microbiome through oral, gastric and stool samples and compare hospital-acquired infections.

NCT05541068
Patients with heart failure (HF) have poor prognosis with high mortality and readmission rates. Diuretic therapy is the usual way of managing congestion, but sometimes is difficult to determine when we have reached euvolemia. Even in overweight and obese patients in which physical examination and usual diagnostic techniques have strong limitations. The aim of this study is to investigate the usefulness of bioelectrical impedance analysis (BIA) in management and treatment of HF in overweight and obese patients. The study included overweight and obese patients who were admitted with acute decompensated HF. The study population was randomized into two arms: BIA-guided therapy or standard care. Serum electrolytes, kidney functions and natriuretic peptides were followed up during their hospital stay and at 90 days after discharge. The primary endpoint was development of acute kidney injury (AKI) stage III (AKIN-III) during hospitalization and the main secondary endpoint was the reduction of NT-proBNP (N-terminal pro-B-type natriuretic peptide) levels during hospitalization and within 90 days after discharge.

NCT05538611
Heart failure is a chronic disease that spans the home as well as the outpatient and hospital Settings and requires multidisciplinary, continuous disease management. Heart failure management emphasizes seamless connection from admission to return to the family, so as to improve the efficiency of resource use. Early preventive intervention, timely and reasonable drug treatment, integration of effective medical resources, and establishment of A sound and effective management model should be carried out for the population with high risk factors of heart failure (heart function stage A), so as to delay the occurrence and development of heart failure and further avoid the occurrence of malignant cardiovascular events. Therefore, this project aims to establish a "special-general-community-family" chain quality control model with the "general practice department" as the core for patients with chronic heart failure in general hospitals, so as to provide them with a full life cycle, multidimensional, concise and efficient quality control management.At present, the situation of heart failure prevention and treatment in China is grim and the challenge is huge. Heart failure complicated illness, drug dosage adjustment characteristics of professionalism, its emphasis on guide oriented treatment, and should pay attention to individual, need of specialized subject doctor, general practitioners, community doctors and family personal collaborative to maximize the optimal management of patients with chronic heart failure, follow the classification diagnosis and treatment, two-way referral is helpful to improve the long-term prognosis of patients with. At present, HF management has received increasing attention, how to choose a more reasonable, effective and economic management mode is still a problem of disagreement.
NCT05539781
The majority (\>80%) of strokes are of ischemic etiology, of which ≈15% to 20% are attributable to atherosclerosis of the extracranial carotid arteries. The primary goal in carotid artery revascularization is to prevent stroke in patients with carotid artery stenosis. Treatment options including carotid endarterectomy (CEA) and carotid artery stenting (CAS). Hence, the investigators aim to compare carotid artery stenting (CAS) with carotid endarterectomy (CEA) in terms of long-term prognostic endpoints. Also, CEA and CAS result in different postoperative geometric features of carotid arteries that entail relevant modifications of rheological parameters, that may be associated with the risk of local complications and carotid artery restenosis. Finally, long-term and sustained cognitive benefits after carotid artery revascularization need further research and evidence.
NCT03487302
The study aims at investigating the role of cyanotic congenital heart disease (cCHD) on brain aging. The investigators assume that due to congenital and acquired cardiovascular abnormalities, cCHD patients could show radiologic (and clinical) signs of precocious brain aging and eventual cognitive decline.
