Familial hypercholesterolemia : review article

La hipercolesterolemia familiar (HF) es una alteración de origen genético que clínicamente se puede manifestar desde el nacimiento y que se caracteriza por niveles plasmáticos anormalmente altos de colesterol LDL (cLDL) y por una elevada tasa de morbimortalidad cardiovascular prematura. Tiene dos formas de presentación: la HF heterocigótica (HFHe) y la HF homocigótica (HFHo); esta última más severa y de aparición clínica en los primeros años de vida. Históricamente, la prevalencia para la HFHe es de un caso en 500 personas y para la HFHo de un caso por cada millón de personas; sin embargo, los datos reales probablemente son superiores porque hay evidencia de que ambas condiciones están subdiagnosticadas. La terapia recomendada, además de los cambios en el estilo de vida, son las estatinas; sin embargo, con estos fármacos es difícil lograr en muchos casos reducciones aceptables del cLDL, por lo que se requiere asociar otras modalidades terapéuticas, algunas de ellas recientemente aprobadas. Dado que en Colombia no se ha publicado ningún documento de revisión sobre HF, la Sociedad Colombiana de Cardiología y Cirugía Cardiovascular convocó a diferentes especialidades de la medicina para elaborar un documento sobre el tema, que resumiera, de manera práctica y actualizada, aspectos clínicos, genéticos, diagnósticos y de tratamiento.Q44-26Familial hypercholesterolemia (FH) is a genetic disorder that may clinically manifest since birth and is characterized by abnormally high plasma LDL cholesterol (LDLc) levels and a high early cardiovascular morbidity and mortality rate. FH has two presentation forms: heterozygous FH (HeFH) and homozygous FH (HoFH), the latter being more severe and with a clinical onset during the first few years of life. Historically, HeFH prevalence is of 1:500 and HoFH of 1:1 million; however, real data are probably higher because evidence indicated that both conditions are underdiagnosed. Recommended therapy, besides lifestyle changes, are statins; nevertheless, these drugs make it difficult in many cases to achieve reasonable cLDL reductions, therefore an association with other therapeutic models, some of which have recently been approved, is required. Since no review papers have been published in Colombia regarding FH, the Colombian Cardiology and Cardiovascular Surgery Society invited several medical specialties to draft a document on the subject that would sum up, in a practical and updated way, clinical, genetics, diagnostics and therapeutic aspects

Empagliflozin in Heart Failure with a Preserved Ejection Fraction.

BACKGROUND: Sodium-glucose cotransporter 2 inhibitors reduce the risk of hospitalization for heart failure in patients with heart failure and a reduced ejection fraction, but their effects in patients with heart failure and a preserved ejection fraction are uncertain. METHODS: In this double-blind trial, we randomly assigned 5988 patients with class II-IV heart failure and an ejection fraction of more than 40% to receive empagliflozin (10 mg once daily) or placebo, in addition to usual therapy. The primary outcome was a composite of cardiovascular death or hospitalization for heart failure. RESULTS: Over a median of 26.2 months, a primary outcome event occurred in 415 of 2997 patients (13.8%) in the empagliflozin group and in 511 of 2991 patients (17.1%) in the placebo group (hazard ratio, 0.79; 95% confidence interval [CI], 0.69 to 0.90; P<0.001). This effect was mainly related to a lower risk of hospitalization for heart failure in the empagliflozin group. The effects of empagliflozin appeared consistent in patients with or without diabetes. The total number of hospitalizations for heart failure was lower in the empagliflozin group than in the placebo group (407 with empagliflozin and 541 with placebo; hazard ratio, 0.73; 95% CI, 0.61 to 0.88; P<0.001). Uncomplicated genital and urinary tract infections and hypotension were reported more frequently with empagliflozin. CONCLUSIONS: Empagliflozin reduced the combined risk of cardiovascular death or hospitalization for heart failure in patients with heart failure and a preserved ejection fraction, regardless of the presence or absence of diabetes.

The Changing Landscape for Stroke\ua0Prevention in AF: Findings From the GLORIA-AF Registry Phase 2

Background GLORIA-AF (Global Registry on Long-Term Oral Antithrombotic Treatment in Patients with Atrial Fibrillation) is a prospective, global registry program describing antithrombotic treatment patterns in patients with newly diagnosed nonvalvular atrial fibrillation at risk of stroke. Phase 2 began when dabigatran, the first non\u2013vitamin K antagonist oral anticoagulant (NOAC), became available. Objectives This study sought to describe phase 2 baseline data and compare these with the pre-NOAC era collected during phase&nbsp;1. Methods During phase 2, 15,641 consenting patients were enrolled (November 2011 to December 2014); 15,092 were eligible. This pre-specified cross-sectional analysis describes eligible patients\u2019 baseline characteristics. Atrial fibrillation&nbsp;disease characteristics, medical outcomes, and concomitant diseases and medications were collected. Data were analyzed using descriptive statistics. Results Of the total patients, 45.5% were female; median age was 71 (interquartile range: 64, 78) years. Patients were from Europe (47.1%), North America (22.5%), Asia (20.3%), Latin America (6.0%), and the Middle East/Africa (4.0%). Most had high stroke risk (CHA2DS2-VASc [Congestive heart failure, Hypertension, Age&nbsp; 6575 years, Diabetes mellitus, previous Stroke, Vascular disease, Age 65 to 74 years, Sex category] score&nbsp; 652; 86.1%); 13.9% had moderate risk (CHA2DS2-VASc&nbsp;= 1). Overall, 79.9% received oral anticoagulants, of whom 47.6% received NOAC and 32.3% vitamin K antagonists (VKA); 12.1% received antiplatelet agents; 7.8% received no antithrombotic treatment. For comparison, the proportion of phase 1 patients (of N&nbsp;= 1,063 all eligible) prescribed VKA was 32.8%, acetylsalicylic acid 41.7%, and no therapy 20.2%. In Europe in phase 2, treatment with NOAC was more common than VKA (52.3% and 37.8%, respectively); 6.0% of patients received antiplatelet treatment; and 3.8% received no antithrombotic treatment. In North America, 52.1%, 26.2%, and 14.0% of patients received NOAC, VKA, and antiplatelet drugs, respectively; 7.5% received no antithrombotic treatment. NOAC use was less common in Asia (27.7%), where 27.5% of patients received VKA, 25.0% antiplatelet drugs, and 19.8% no antithrombotic treatment. Conclusions The baseline data from GLORIA-AF phase 2 demonstrate that in newly diagnosed nonvalvular atrial fibrillation patients, NOAC have been highly adopted into practice, becoming more frequently prescribed than VKA in&nbsp;Europe and North America. Worldwide, however, a large proportion of patients remain undertreated, particularly in&nbsp;Asia&nbsp;and North America.

Angina de Prinzmetal Angina de Prinzmetal Prinzmetal's angina

Essa síndrome é causada por um espasmo focal de uma artéria coronária epicárdica, levando a isquemia miocárdica grave. Embora freqüentemente acredite-se que o espasmo ocorra em artérias sem estenose, muitos pacientes com angina de Prinzmetal apresentam espasmo adjacente a placas ateromatosas. A causa exata do espasmo não está bem definida, mas pode estar relacionada à hipercontratilidade do músculo liso vascular devido a mitógenos vasoconstrictores, leucotrienos ou serotonina. Em alguns pacientes, é uma manifestação de distúrbio vasoespástico e está associado à migrânea, fenômeno de Raynaud ou asma induzida por aspirina. Apresentamos um caso associado com depressão transitória do segmento ST.<br>Este síndrome es causado por un espasmo focal de una arteria coronaria epicárdica, llevando a isquemia miocárdica grave.

Although it is frequently thought that the spasm occurs in arteries without stenosis, many Prinzmetal patients have spasm adjacent to atheromatous plaques. The exact cause of the spasm has not been well defined, but it may be related to the hypercontractility of the vascular smooth muscle due to vasoconstrictor mitogens, leukotrienes, or serotonin. In some patients, it is a manifestation of a vasospastic disorder and it is associated with migraine, Raynaud's phenomenon, or aspirin-induced asthma. We present a case associated with transient ST-segment depression

A multi-national registry to study the characteristics and outcomes of heart failure patients : The global congestive heart failure (G-CHF) registry

Aims The goal of the global congestive heart failure (G-CHF) registry is to collect comparative international data on heart failure characteristics, management, and outcomes and to better understand the determinants that impact the clinical course of heart failure. Methods G-CHF is a multicenter, prospective cohort study of adult patients with a new or prior clinical diagnosis of heart failure. We have enrolled 23,047 participants from 257 centers in 40 countries from 8 major geographic regions of the world, with recruitment ongoing. Approximately 4,000 participants will also participate in substudies to assess frailty, comorbidity, diet, barriers to care, biomarkers, and planned detailed echocardiographic analyses. Follow-up is planned for a period of 5 years. The primary outcome is cause-specific mortality. Key secondary outcomes include hospitalizations, quality of life, and major cardiovascular and noncardiovascular outcomes. A total of 31.9% of participants were enrolled as inpatients. Thus far, mean age of the cohort at baseline is 63.1 years, and 60.8% are male. Participants most commonly have heart failure with reduced ejection fraction (53.6%) followed by preserved ejection fraction (24.2%) and midrange ejection fraction (20.6%). The most common causes of heart failure are ischemic (37.8%) followed by hypertensive (20.0%), idiopathic (15.1%), and valvular disease (8.8%). Conclusion G-CHF will provide a greater understanding of the characteristics of the global heart failure population, variations in its management, clinical outcomes, and what continues to impact morbidity and mortality in this high-risk population

Efficacy of empagliflozin in heart failure with preserved versus mid-range ejection fraction: a pre-specified analysis of EMPEROR-Preserved.

The EMPEROR-Preserved trial showed that the sodium-glucose co-transporter 2 inhibitor empagliflozin significantly reduces the risk of cardiovascular death or hospitalization for heart failure (HHF) in heart failure patients with left ventricular ejection fraction (LVEF)  > 40%. Here, we report the results of a pre-specified analysis that separately evaluates these patients stratified by LVEF: preserved (≥ 50%) (n = 4,005; 66.9%) or mid-range (41-49%). In patients with LVEF  ≥ 50%, empagliflozin reduced the risk of cardiovascular death or HHF (the primary endpoint) by 17% versus placebo (hazard ratio (HR) 0.83; 95% confidence interval (CI): 0.71-0.98, P = 0.024). For the key secondary endpoint, the HR for total HHF was 0.83 (95%CI: 0.66-1.04, P = 0.11). For patients with an LVEF of 41-49%, the HR for empagliflozin versus placebo was 0.71 (95%CI: 0.57-0.88, P = 0.002) for the primary outcome (Pinteraction = 0.27), and 0.57 (95%CI: 0.42-0.79, P < 0.001) for total HHF (Pinteraction = 0.06). These results, together with those from the EMPEROR-Reduced trial in patients with LVEF < 40%, support the use of empagliflozin across the full spectrum of LVEF in heart failure
