Effect of Tafamidis on Clinical and Functional Parameters in Transthyretin Amyloid Cardiomyopathy.

Background: Transthyretin amyloid cardiomyopathy (ATTR-CM) has recently gained recognition as a rare and fatal disease. Tafamidis, a first-in-class transthyretin stabilizer, has emerged as a promising agent for attenuating disease progression. Nevertheless, how tafamidis alters clinical and imaging parameters remains unclear.

Left atrial reservoir strain as a surrogate marker for atrial fibrillation burden in patients with non-valvular atrial fibrillation.

Background: To evaluate the correlation between atrial fibrillation (AF) burden and two-dimensional LA (left atrium) longitudinal reservoir strain (LARS) to explore the potential clinical utility of this novel parameter in patients with AF.

Methods: This cross-sectional study was conducted at the cardiac electrophysiology clinic of a tertiary centre by consecutively enrolling patients with non-valvular AF. The AF burden was evaluated using 14-day patch-based electrocardiography and defined as the percentage of time spent in AF during a 14-day monitoring period.

Impact of Tafamidis on [Tc]Tc-pyrophosphate Scintigraphy in Ala97Ser Hereditary Transthyretin amyloid cardiomyopathy: significant initial reduction with stable Long-Term effects.

Objective: Tafamidis has shown potential in slowing disease progression in patients with transthyretin amyloid cardiomyopathy (ATTR-CM). This study aimed to evaluate serial changes on [Tc]Tc-pyrophosphate (PYP) scintigraphy during tafamidis treatment for hereditary ATTR-CM.

Methods: We retrospectively analyzed a prospectively collected cohort of Ala97Ser (A97S) hereditary ATTR-CM patients treated with tafamidis (61 mg/day) and a control group comprising A97S hereditary ATTR-CM patients who had not received disease-modifying medications.

Tafamidis improves myocardial longitudinal strain in A97S transthyretin cardiac amyloidosis.

Background: Transthyretin cardiomyopathy (ATTR-CM) is a debilitating disease that has received much attention since the emergence of novel treatments. The Transthyretin Cardiomyopathy Clinical Trial showed that tafamidis, a transthyretin tetramer stabilizer, effectively reduced the declines in functional capacity and quality of life. However, Ala97Ser (A97S) hereditary ATTR-CM is underrepresented in major ATTR-CM tafamidis trials.

Tafamidis decreased cardiac amyloidosis deposition in patients with Ala97Ser hereditary transthyretin cardiomyopathy: a 12-month follow-up cohort study.

Background: Transthyretin cardiac cardiomyopathy (ATTR-CM) is a rare but life-threatening disease. Tafamidis is an effective treatment for patients with ATTR-CM, however its long-term effects on cardiac remodeling and cardiac amyloid deposition are unknown. This study aimed to used cardiac magnetic resonance (CMR) to investigate the effects of tafamidis on patients with hereditary A97S ATTR-CM.

Differential effects of sodium-glucose cotransporter 2 inhibitors on cardiovascular and renal outcomes according to renal function: a dose-response meta-analysis involving 10 randomized clinical trials and 71 553 individuals.

Background: The main target of sodium-glucose cotransporter 2 inhibitors (SGLT2i), the sodium-glucose cotransporters 2, is found in the kidneys, and their activity is reduced in patients with chronic kidney disease (CKD). How the efficacy of SGLT2i may vary in patients with different levels of renal impairment has not been fully elucidated.

Methods: We searched the PubMed databases for relevant studies published through May 25, 2022.

Pulmonary artery catheter usage in diagnosis of Shoshin beriberi presented with unexplained lactic acidosis.

Wet beriberi is a rare but fatal disease in modern society. The nonspecific clinical manifestations, including symptoms of heart failure and recalcitrant lactic acidosis, can prevent timely diagnosis. The use of a pulmonary artery catheter can promptly confirm a high cardiac output state and plays a crucial role in rapidly deteriorating cases.

Major adverse cardiovascular and limb events in people with diabetes treated with GLP-1 receptor agonists vs SGLT2 inhibitors.

Aims/hypothesis: This study aimed to assess the real-world outcomes of people with diabetes mellitus treated with glucagon-like peptide-1 receptor agonists (GLP1RAs) compared with those treated with sodium-glucose cotransporter 2 inhibitors (SGLT2is) in terms of major adverse cardiovascular and limb events. Peripheral artery disease is a common cause of morbidity in people with diabetes. Previous cardiovascular outcome trials have demonstrated the benefits of GLP1RAs and SGLT2is for reducing various cardiovascular events, but the safety and efficacy of these drugs on limb outcomes remain subject to debate and ambiguity.

Mortality risk in patients with underweight or obesity with peripheral artery disease: a meta-analysis including 5,735,578 individuals.

Objectives: The "obesity paradox" - in which patients with obesity exhibit superior survival than normal-weight counterparts - has been reported for several diseases. However, obesity is a well-known risk factor for cardiovascular disease, and whether the obesity paradox is present in peripheral artery disease (PAD) is unknown.

Methods: A comprehensive search for studies that reported mortality in patients with PAD grouped by BMI identified 12 studies.

A Dose Response Association Between Body Mass Index and Mortality in Patients with Peripheral Artery Disease: A Meta-analysis Including 5 729 272 Individuals.

Objective: Obesity is a significant risk factor for atherosclerotic cardiovascular disease; however, the "obesity paradox", in which obese patients enjoy superior survival, has been observed in various cardiovascular conditions. Whether this phenomenon exists for peripheral artery disease (PAD) remains uncertain. The goal of this study was to evaluate the relationship between body mass index (BMI) and mortality in patients with PAD.

affects anther dehiscence in a male-sterile line.

Anther indehiscence is an important form of functional male sterility that can facilitate the production of hybrid seed; however, the molecular mechanisms of anther indehiscence-based male sterility have not been thoroughly explored in eggplant ( L.). Here, we used two-dimensional gel electrophoresis to compare the protein profiles in the anthers of normally developing (F142) and anther indehiscent (S16) plants.
