Efficacy of Oral Acetazolamide as Add-on Diuretic Therapy in Decongestion in Patients with Heart Failure: A Study Protocol for a Randomized Controlled Trial.

Background: Acute heart failure is a common clinical syndrome leading to hospital admission, with few evidence-based therapies for managing congestion. This trial aims to assess the efficacy of acetazolamide combined with loop diuretics in achieving decongestion among patients who fail to respond to oral diuretics and progress to acute decompensated heart failure in the absence of injectable furosemide.

Methods: This single-center, double-blind randomized controlled trial with a 1:1 allocation ratio aims to evaluate 130 patients admitted to the infusion ward.

Methods: A total of 947 individuals referred to the cardiology clinic who have not used statin or take low-dose statin were evaluated through a cross-sectional study.

Comparing HeartModel and cardiac magnetic resonance imaging for left ventricular volume and function evaluation in patients with dilated cardiomyopathy.

Background: Integration of artificial intelligence enhances precision, yielding dependable evaluations of left ventricular volumes and ejection fraction despite image quality variations. Commercial software like HeartModel provides fully automated 3DE quantification, simplifying the measurement of left chamber volumes and ejection fraction. In this manuscript, we present a cross-sectional study to assess and compare the diagnostic accuracy of automated 3D echocardiography (HeartModel) to the standard Cardiac Magnetic Resonance Imaging in patients with dilated cardiomyopathy.

Marital Quality-A Neglected Player in the Prevention of Cardiovascular Diseases: A Systematic Review of Longitudinal Studies.

Purpose Of Review: Marital quality (MQ) is a psychosocial factor that has been neglected in cardiovascular prevention guidelines, although its association with cardiovascular diseases has been identified in several studies. Therefore, we aim to investigate how MQ either in positive or negative dimensions affect different cardiovascular risk factors and diseases.

Recent Findings: We systematically searched different databases in September 2023 for longitudinal studies conducted to assess the contribution of MQ to well-established cardiovascular risk factors and diseases.

Serum levels of trimethylamine N-oxide and kynurenine novel biomarkers are associated with adult metabolic syndrome and its components: a case-control study from the TEC cohort.

Background: Epidemiologic research suggests that gut microbiota alteration (dysbiosis) may play a role in the pathogenesis of metabolic syndrome (MetS). Dysbiosis can influence Trimethylamine N-oxide (TMAO) a gut microbiota-derived metabolite, as well as kynurenine pathways (KP), which are known as a new marker for an early predictor of chronic diseases. Hence, the current study aimed to investigate the association between KYN and TMAO with MetS and its components.

Methods: The study analyzed 1182 adults aged 20+ in the Tehran University of Medical Sciences (TUMS) Employee's Cohort study (TEC), focusing on dietary intakes, angina, and atherogenic indexes, using a validated food frequency questionnaire (FFQ) and the Rose Angina Questionnaire (RAQ).

Blood Pressure Control Following Angiotensin-Converting Enzyme Inhibitors and Angiotensin II Receptor Blockers: Insights from a Triple-Blind, Randomized, Clinical Trial.

Data on substituting one antihypertensive medication with the proper dose of another antihypertensive medication, in certain medical conditions, are scarce. Herein, we present the results of replacing angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs) with the calcium channel blocker (CCB) amlodipine, with or without the alpha- and beta-blocker carvedilol, to control high blood pressure in patients with coronavirus disease 2019 (COVID-19). Iranian hypertensive patients with COVID-19 and a history of taking ACEI or ARB were randomized to "continue" and "change" groups.

A total of 548 consecutive patients with ST-elevation myocardial infarction who underwent primary percutaneous coronary intervention between November 2016 and January 2019 were evaluated.

Effects of angiotensin receptor blockers (ARBs) on clinical outcomes of patients with hypertension and COVID-19: A 7-month follow-up cohort study.

Since the coronavirus disease 2019 (COVID-19) pandemic, the use of angiotensin II receptor blockers (ARBs) in hypertensive patients with COVID-19 has been controversial. Following our previous study, after one year, we intended to extend our sample size and results to investigate the effects of ARBs with both in-hospital outcomes and 7-month follow-up results in patients with COVID-19. Patients with a diagnosis of COVID-19 who were admitted to Sina Hospital, Tehran, Iran, from February to October 2020 participated in this follow-up cohort study.

ACC/AHA/HFSA 2022 and ESC 2021 guidelines on heart failure comparison.

The 2022 American College of Cardiology/American Heart Association/Heart Failure Society of America (ACC/AHA/HFSA) and the 2021 European Society of Cardiology (ESC) both provide evidence-based guides for the diagnosis and treatment of heart failure (HF). In this review, we aimed to compare recommendations suggested by these guidelines highlighting the differences and latest evidence mentioned in each of the guidelines. While the staging of HF depends on left ventricular ejection fraction, the Universal Definition of HF, suggested in 2021, is described in 2022 ACC/AHA/HFSA guidelines.
