  • Doctors use a special scan called coronary CTA to check for heart problems, and there's a new AI tool that helps figure out if a patient has low blood flow to the heart muscle.
  • This study looked at how well this AI tool can predict serious health problems, like death or heart attacks, in patients who might have heart disease.
  • The results showed that if the AI tool finds something wrong, those patients may have a higher chance of serious issues, especially if they have non-obstructive heart disease.

Department for BioMedical Research, University Hospital Inselspital, University of Bern, 3010 Bern, Switzerland; Department of Nephrology and Hypertension, University Hospital Inselspital, University of Bern, 3010 Bern, Switzerland.

Aldosterone synthase (CYP11B2) represents a promising drug target because its genetic dysregulation is causally associated with cardiovascular disease, its autonomous activity leads to primary aldosteronism, and its deficiency leads to salt wasting syndromes. The serendipitous discovery that the dextro-rotatory stereoisomer of the racemic aromatase (CYP19A1) inhibitor CGS16949A mediates potent CYP11B2 inhibition led to the purification and clinical development of dexfadrostat phosphate. To characterize the pharmacophore of dexfadrostat phosphate, structure-based enzyme coordination with CYP11B2, CYP11B1 and CYP19A1 was combined with steroid turnover upon in vitro and clinical treatment.

Whereas exercise training, as part of multidisciplinary rehabilitation, is a key component in the management of patients with chronic coronary syndrome (CCS) and/or congestive heart failure (CHF), physicians and exercise professionals disagree among themselves on the type and characteristics of the exercise to be prescribed to these patients, and the exercise prescriptions are not consistent with the international guidelines. This impacts the efficacy and quality of the intervention of rehabilitation. To overcome these barriers, a digital training and decision support system [i.

Background: We aimed to evaluate the quality of life (QoL), using patient-reported outcome measures (PROMs), in elderly patients with venous thromboembolism (VTE) and to explore whether VTE complications (recurrence, bleeding, or postthrombotic syndrome) had an impact on later QoL.

Methods: We used data from the SWIss venous Thromboembolism COhort of older patients(SWITCO65+), a prospective multicenter cohort of patients aged ≥65 years with acute, symptomatic VTE. Primary outcome was changes in QoL up to 24 months, assessed using generic (36-Item Short-Form Health Survey), with physical (PCS) and mental component score (MCS), and disease-specific (Venous Insufficiency Epidemiological and Economic Study [VEINES]-QoL, [VEINES-Sym], and Pulmonary Embolism QoL) PROMs.

Cancer and cardiovascular diseases (CVD) often share common risk factors, and patients with CVD who develop cancer are at high risk of experiencing major adverse cardiovascular events. Additionally, cancer treatment can induce short- and long-term adverse cardiovascular events. Given the improvement in oncological patients' prognosis, the burden in this vulnerable population is slowly shifting towards increased cardiovascular mortality.

(1) Background: Upfront treatment consolidation with high-dose chemotherapy (HDCT) and autologous stem cell transplantation (ASCT) has relevantly contributed to achieving durable remissions following induction treatment in multiple myeloma (MM) patients. The optimization of HDCT regimens can, therefore, essentially contribute to improving the depth and duration of tumor remissions. To date, melphalan at 200 mg/m is the standard HDCT regimen for fit MM patients.
