Relation between periodontal disease and ischemic heart disease

The aim of this study was to determine the association between periodontal diseases and ischemic heart disease among 30 exercise tolerance test (ETT) positive and 30 ETT negative of ischemic heart disease patients attending the National Heart Foundation Hospital and Research Institute. The presence of gum swelling for the two groups were statistically significant. The results revealed that 80% ETT positive and 23% ETT negative respondent had gum bleeding, 53% ETT positive and 7% ETT negative had ulceration of gingiva. Furthermore, severely inflamed with spontaneous bleeding was found in 53.3% ETT positive and 6.7% negative respondents. It can be concluded that oral hygiene should be promoted as a part of prevention of ischemic heart disease

Evaluation of clinical parameters related to methotrexate therapy in lichen planus

Background: For better management of lichen planus a clinical trial of oral methotrexate is necessary in ow· country. Objective: The objective of this study is to evaluate efficacy and safety ofmethotrexate therapy in the treatment of lichen planus.Methods: It was a prospective randomized controlled clinical trial conducted in the department of Dermatology and Venereology, BSMMU, Dhaka, from January 2009 to December 2010. Forty four patients of lichen planus were included in the study. Cases (group-A, n=23) were treated with methotrexate (10 mg) single morning dose and control (group-B, n=21) were treated with mini pulse betamethasone (5mg) single morning dose on 2 consecutive days during the period of 12 weeks. Results: Clinical parameters were measured by follow up clinical examination. Morphological lesion of lichen planus improved 95. 7% in group-A and only 28.6% improved in group-B. At the end of study 82.6% bad no complaints of itching in group-A and 100% had no complaints of itching in group-B. 16(69.6%) patients in group-A were completely cured clinically but 10(47.6%) in group-B. Anemia 3(14.2%) and edema 12(57.1 %) developed in group-B but none in group-A. In group-B, dyspepsia 15(71.4%), acne 10(47.6%),mooning face 8(38.1%), striae 8(38.1%) and hyper­trichosis 4(19.0%) developed but none in group-A lntermittenr diarrhoea, headache, nausea and fatigue complained in both groups of patients but the percentage of complaints was higher amog group-8 compared to group-A. Menstrual abnormality developed in group-B 5(71.4%) but none in group-A.Conclusion: The overall adverse effects were less in group-A than group-B. Therefore, methotrexate can be used as an alternative safer option for the treatment of lichen planus

OBJECTIVES The authors sought to evaluate interim results from the EXPLORER-Long Term Extension (LTE) cohort of MAVA-LTE (A Long-Term Safety Extension Study of Mavacamten in Adults Who Have Completed EXPLORER-HCM; NCT03723655). METHODS After mavacamten or placebo withdrawal at the end of the parent EXPLORER-HCM (Clinical Study to Evaluate Mavacamten [MYK-461] in Adults With Symptomatic Obstructive Hypertrophic Cardiomyopathy; NCT03470545), patients could enroll in MAVA-LTE. Patients received mavacamten 5 mg once daily; adjustments were made based on site-read echocardiograms. RESULTS Between April 9, 2019, and March 5, 2021, 231 of 244 eligible patients (94.7%) enrolled in MAVA-LTE (mean age: 60 years; 39% female). At data cutoff (August 31, 2021) 217 (93.9%) remained on treatment (median time in study: 62.3 weeks; range: 0.3-123.9 weeks). At 48 weeks, patients showed improvements in left ventricular outflow tract (LVOT) gradients (mean change ± SD from baseline: resting: -35.6 ± 32.6 mm Hg; Valsalva: -45.3 ± 35.9 mm Hg), N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels (median: -480 ng/L; Q1-Q3: -1,104 to -179 ng/L), and NYHA functional class (67.5% improved by ≥1 class). LVOT gradients and NT-proBNP reductions were sustained through 84 weeks in patients who reached this timepoint. Over 315 patient-years of exposure, 8 patients experienced an adverse event of cardiac failure, and 21 patients had an adverse event of atrial fibrillation, including 11 with no prior history of atrial fibrillation. Twelve patients (5.2%) developed transient reductions in site-read echocardiogram left ventricular ejection fraction of <50%, resulting in temporary treatment interruption; all recovered. Ten patients discontinued treatment due to treatment-emergent adverse events. CONCLUSIONS Mavacamten treatment showed clinically important and durable improvements in LVOT gradients, NT-proBNP levels, and NYHA functional class, consistent with EXPLORER-HCM. Mavacamten treatment was well tolerated over a median 62-week follow-up.S

Exercise Capacity in Patients With Obstructive Hypertrophic Cardiomyopathy:SEQUOIA-HCM Baseline Characteristics and Study Design

Patients with obstructive hypertrophic cardiomyopathy (oHCM) have increased risk of arrhythmia, stroke, heart failure, and sudden death. Contemporary management of oHCM has decreased annual hospitalization and mortality rates, yet patients have worsening health-related quality of life due to impaired exercise capacity and persistent residual symptoms. Here we consider the design of clinical trials evaluating potential oHCM therapies in the context of SEQUOIA-HCM (Safety, Efficacy, and Quantitative Understanding of Obstruction Impact of Aficamten in HCM). This large, phase 3 trial is now fully enrolled (N = 282). Baseline characteristics reflect an ethnically diverse population with characteristics typical of patients encountered clinically with substantial functional and symptom burden. The study will assess the effect of aficamten vs placebo, in addition to standard-of-care medications, on functional capacity and symptoms over 24 weeks. Future clinical trials could model the approach in SEQUOIA-HCM to evaluate the effect of potential therapies on the burden of oHCM.

Phase 2 study of aficamten in patients with obstructive hypertrophic cardiomyopathy

Background: Left ventricular outflow tract (LVOT) obstruction is a major determinant of heart failure symptoms in obstructive hypertrophic cardiomyopathy (oHCM). Aficamten, a next-in-class cardiac myosin inhibitor, may lower gradients and improve symptoms in these patients. Objectives: This study aims to evaluate the safety and efficacy of aficamten in patients with oHCM. Methods: Patients with oHCM and LVOT gradients ≥30 mm Hg at rest or ≥50 mm Hg with Valsalva were randomized 2:1 to receive aficamten (n = 28) or placebo (n = 13) in 2 dose-finding cohorts. Doses were titrated based on gradients and ejection fraction (EF). Safety and changes in gradient, EF, New York Heart Association functional class, and cardiac biomarkers were assessed over a 10-week treatment period and after a 2-week washout. Results: From baseline to 10 weeks, aficamten reduced gradients at rest (mean difference: −40 ± 27 mm Hg, and −43 ± 37 mm Hg in Cohorts 1 and 2, P = 0.0003 and P = 0.0004 vs placebo, respectively) and with Valsalva (−36 ± 27 mm Hg and −53 ± 44 mm Hg, P = 0.001 and &lt;0.0001 vs placebo, respectively). There were modest reductions in EF (−6% ± 7.5% and −12% ± 5.9%, P = 0.007 and P &lt; 0.0001 vs placebo, respectively). Symptomatic improvement in ≥1 New York Heart Association functional class was observed in 31% on placebo, and 43% and 64% on aficamten in Cohorts 1 and 2, respectively (nonsignificant). With aficamten, N-terminal pro–B-type natriuretic peptide was reduced (62% relative to placebo, P = 0.0002). There were no treatment interruptions and adverse events were similar between treatment arms. Conclusions: Aficamten resulted in substantial reductions in LVOT gradients with most patients experiencing improvement in biomarkers and symptoms. These results highlight the potential of sarcomere-targeted therapy for treatment of oHCM

Efficacy and safety of aficamten in symptomatic non-obstructive hypertrophic cardiomyopathy: results from the REDWOOD-HCM trial, cohort 4

Background This open-label phase 2 trial evaluated the safety and efficacy of aficamten in patients with nonobstructive hypertrophic cardiomyopathy (nHCM). Methods Patients with symptomatic nHCM (left ventricular outflow tract obstruction gradient ≤ 30 mmHg, left ventricular ejection fraction [LVEF] ≥ 60%, N-terminal pro-B-type natriuretic peptide [NT-proBNP] &gt; 300 pg/mL) received aficamten 5–15 mg once daily (doses adjusted according to echocardiographic LVEF) for 10 weeks. Results We enrolled 41 patients (mean ± SD age 56 ± 16 years; 59% female). At Week 10, 22 (55%) patients experienced an improvement of ≥ 1 New York Heart Association class; 11 (29%) became asymptomatic. Clinically relevant improvements in Kansas City Cardiomyopathy Questionnaire Clinical Summary Scores occurred in 22 (55%) patients. Symptom relief was paralleled by reductions in NT-proBNP levels (56%; P &lt; 0.001) and high-sensitivity cardiac troponin I (22%; P &lt; 0.005). Modest reductions in LVEF (mean ± SD) of −5.4% ± 10 to 64.6% ± 9.1 were observed. Three (8%) patients had asymptomatic reduction in LVEF &lt; 50% (range: 41%–48%), all returning to normal after 2 weeks of washout. One patient with prior history of aborted sudden cardiac death experienced a fatal arrhythmia during the study. Conclusions Aficamten administration for symptomatic nHCM was generally safe and was associated with improvements in heart failure symptoms and cardiac biomarkers
