BACKGROUND: Risk stratification for patients with non-ischemic cardiomyopathy (NICM) remains challenging as previous studies predicting life-threatening ventricular arrhythmia (LTVA) events were conducted before the establishment of the current standard treatment. We investigated the prognostic value of non-sustained ventricular tachycardia (NSVT) in NICM patients among recent studies. METHODS: MEDLINE, Embase were searched from January 2000 to October 2023. The risk of NSVT on LTVA and mortality was assessed using a random-effects model for patients with NICM...

BACKGROUND: There is a scarcity of data on the prevalence of abnormal findings on preprocedural computed tomography (CT) before aortic valve replacement (AVR) in patients with aortic stenosis (AS). METHODS: Among consecutive 593 patients with severe AS who were planned to undergo AVR, we evaluated the prevalence of clinically significant incidental noncardiac findings on preprocedural CT. Clinically significant incidental noncardiac findings were defined as newly detected abnormalities that required therapy, consultation for expert, further investigation, or clinical follow-up...

BACKGROUND: Multi-parametric assessment, including heart sounds in addition to conventional parameters, may enhance the efficacy of noninvasive telemonitoring for heart failure (HF). We sought to assess the feasibility of self-telemonitoring with multiple devices including a handheld heart sound recorder and its association with clinical events in patients with HF. METHODS: Ambulatory HF patients recorded their own heart sounds, mono‑lead electrocardiograms, oxygen saturation, body weight, and vital signs using multiple devices every morning for six months...

BACKGROUND: The adaptive cardiac resynchronization therapy (aCRT) algorithm enables synchronized left ventricular pacing (sLVP) to achieve fusion with intrinsic right ventricular activation. Although sLVP presents benefits over biventricular pacing, the adequate sLVP rate for better clinical outcomes remains unclear. We aimed to assess the association between sLVP rates and clinical outcomes. METHODS: Our study cohort included 271 consecutive patients, who underwent CRT implantation between April 2016 and August 2021...

BACKGROUND: The relationship between baseline yellow plaque (YP) and vascular response after stent implantation has not been fully investigated. METHODS: This was a sub-analysis of the Collaboration-1 study (multicenter, retrospective, observational study). A total of 88 lesions from 80 patients with chronic coronary syndrome who underwent percutaneous coronary intervention were analyzed. Optical coherence tomography (OCT) and coronary angioscopy (CAS) were serially performed immediately and 11 months after stent implantation...

INTRODUCTION: Acute decompensated heart failure (ADHF) is a global health problem and early detection of high-risk patients for effective treatment is important. Exhaled breath analysis and measurement of volatile organic compounds (VOCs) may be a fast and cost-effective non-invasive diagnostic and screening tool complementing measurement of cardiac biomarkers. Another technique to detect and characterize VOCs is the ion mobility spectrometry (IMS) not requiring vacuum or sample pretreatment...

The tricuspid valve is known as "the forgotten valve". Tricuspid regurgitation (TR) is a highly prevalent valvular heart disease. TR is often late in the course of the disease when it becomes symptomatic, often being a marker of late-stage chronic heart failure with a poor prognosis and high mortality rate at long-term follow-up. Despite the clear correlation between TR and mortality, most TR patients are under-treated. Neither pharmacologic nor surgical treatment demonstrates a significant survival benefit...

BACKGROUND: With the widespread use of permanent pacemakers (PPM), and increased mortality associated with pacemaker endocarditis, it is essential to evaluate comorbidities that could potentially increase the risk of infective endocarditis (IE). Heart failure (HF), a common comorbidity, has not been well studied as an independent risk factor for development of IE in individuals with PPM. METHODS: The US National Inpatient Sample database was used to sample individuals with PPM...

BACKGROUND: It is crucial to identify factors that can predict the risk of mortality in patients newly diagnosed with interstitial lung disease (ILD). This study sought to develop and assess a composite scoring system for mortality prediction among ILD patients based on cardiovascular parameters, which were previously reported as predictors of survival. METHODS: We prospectively enrolled patients with newly diagnosed ILD and monitored their survival status for 24 months...

BACKGROUND: Some patients with diabetes are unaware that they are prescribed medications for diabetes. The purpose of this study is to determine, using a Japanese nationwide epidemiologic database, the association between unawareness of being prescribed medication and the risk of developing cardiovascular disease (CVD) in patients with diabetes. METHODS: This observational cohort study analyzed data from the JMDC Claims Database between 2005 and 2022, including 94,048 patients with diabetes treated with medications...

BACKGROUND: The presence of insomnia exhibits a profound association with diverse cardiovascular pathologies. However, its prognostic implications in patients undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis remain ambiguous. METHODS: This retrospective study enrolled patients who underwent TAVR for severe aortic stenosis at a prominent academic center from 2015 to 2022. The impact of insomnia, operationally defined as the prescription of soporific agents, on the two-year composite primary outcome comprising all-cause mortality and hospital readmissions was scrutinized...

BACKGROUND: Aortic valve replacement is recommended for patients with "very severe" aortic stenosis (AS), irrespective of symptomatic manifestation. Nonetheless, the prognostic ramifications of "very severe" AS, as opposed to "severe" AS, subsequent to trans-catheter aortic valve implantation (TAVI) remain enigmatic. METHODS: We enrolled consecutive patients who received TAVI at our institute between May 2015 and April 2021. We scrutinized the impact of baseline "very severe" AS upon 3-year all-cause death or heart failure hospitalization following TAVI, in comparison to "severe" AS...

Cardiac amyloidosis (CA) is related to the aggregation of insoluble fibrous deposits of misfolded proteins within the myocardium. Transthyretin amyloidosis (ATTR) and immunoglobulin light-chain amyloidosis are the main forms of CA. Atrial fibrillation (AF) is a common arrhythmia in CA patients, especially in those with ATTR amyloidosis. Increased atrial preload and afterload, atrial enlargement, enhanced atrial wall stress, and autonomic dysfunction are the main mechanisms of AF in CA patients. CA is associated with the formation of endocardial thrombi and systemic embolism...

Historically, patients with myocarditis were considered for implantable cardioverter defibrillator (ICD) utilization only in the chronic phase of the disease following the development of persistent cardiomyopathy refractory to medical therapy or occurrence of a major ventricular arrhythmic event. However, recent literature has indicated that ventricular arrhythmias are frequently reported even in the acute phase of the disease, challenging the long-standing perception that this disease process was largely reversible...
