Article Abstract
Left ventricular failure is the final common pathway for a wide spectrum of myocardial insults, including systemic hypertension and myocardial infarction. Although left ventricular hypertrophy is an adaptive response to pressure and volume overload, this process becomes maladaptive if left untreated and pathologic cardiac hypertrophy then becomes an important and independent risk factor for the development of heart failure. Despite its importance, the transition from hypertrophy to heart failure in humans is poorly understood. The focus of treatment should be prevention of heart failure and other cardiovascular events, such as stroke and atrial fibrillation. When heart failure is present, treatment with medical and device therapy is then focused on improving functional capacity, increasing survival, and preventing progression to end-stage heart failure.

Proactive esophageal cooling during radiofrequency cardiac ablation: data update including applications in very high-power short duration ablation.
Expert Rev Med Devices
December 2024
NorthShore University Health System, Evanston, IL, USA.
Introduction: Proactive esophageal cooling reduces injury during radiofrequency (RF) ablation of the left atrium (LA) for the treatment of atrial fibrillation (AF). New catheters are capable of higher wattage settings up to 90 W (very high-power short duration, vHPSD) for 4s. Varying power and duration however does not eliminate the risk of thermal injury.

Waldenström macroglobulinemia is a rare cancer of plasma cells characterized by the excessive production of immunoglobulin M (IgM). IgM-associated systemic amyloid light chain (AL) amyloidosis is a rare complication of Waldenström macroglobulinemia, characterized by the misfolding of lambda light chains that deposit in various organs, including the heart. We describe a case of progressive nonischemic cardiomyopathy secondary to Waldenström macroglobulinemia and IgM-associated AL amyloidosis that was refractory to medical therapy and highlight the challenges in diagnosis and management.

Department of Epidemiology, NHC Key Laboratory for Health Technology Assessment, Fudan University School of Public Health, 138 Yi Xue Yuan Road, Shanghai, 200032, China.
Background: Depression is a severe mental disorder commonly co-morbid with diabetes, but it remains to elucidate whether depression is associated with the risks of a wide range of vascular complications in people with type 2 diabetes mellitus (T2DM) and whether metabolic biomarkers may mediate this pathway.
Methods: We conducted this prospective analysis among the participants of the UK Biobank who were diagnosed with T2DM and free of vascular complications at baseline between March 13, 2006 and September 30, 2010. Major depressive disorder (MDD) was ascertained according to the hospital admission records and self-report of doctor-diagnosed conditions, while the presence of depressive symptoms was assessed using the Patient Health Questionnaire-2.
Efficacy and safety of perioperative sintilimab plus platinum-based chemotherapy for potentially resectable stage IIIB non-small cell lung cancer (periSCOPE): an open-label, single-arm, phase II trial.
EClinicalMedicine
January 2025
Department of Thoracic Surgery, National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital & Shenzhen Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Shenzhen, China.
Background: The absolute overall survival (OS) improvement with preoperative chemotherapy or chemoradiotherapy in locally advanced non-small cell lung cancer (NSCLC) patients is controversial and unsatisfactory. We designed this trial to explore the efficacy and safety of perioperative sintilimab plus platinum-based chemotherapy for potentially resectable stage IIIB NSCLC to facilitate further optimization of this therapeutic strategy.
Methods: Patients diagnosed with stage IIIB NSCLC through invasive staging approaches and/or PET/CT scans and evaluated as having a high probability of radical resection of the primary lesion and metastatic lymph nodes with clear pathological margins by a multidisciplinary team were enrolled in this open-label, single-arm, phase II trial at a single centre in China.
Cardiovascular Disease Among Women and Birthing Individuals After Delivering a Child With Congenital Heart Disease.
JACC Adv
January 2025
Division of Cardiology, University of Pennsylvania Perelman School of Medicine, Philadelphia, Pennsylvania, USA.
Background: Individuals have a higher risk of cardiovascular disease later in life if they give birth to a child with congenital heart disease (CHD). The mechanism of this association has not been well documented.
Objectives: The authors aimed to describe the prevalence of cardiovascular disease and risk factors in women and birthing individuals 18 to 23 years after delivery of a child with CHD compared to normative data.
