New Cardiovascular Risk Assessment Techniques for Primary Prevention: JACC Review Topic of the Week.
JOURNAL OF THE AMERICAN COLLEGE OF CARDIOLOGY - 26 Jul 2022
Risk factor-based models fail to accurately estimate risk in select populations, in particular younger individuals. A sizable number of people are also classified as being at intermediate risk, for whom the optimal preventive strategy could be more precise. Several personalized risk prediction tools, including coronary artery calcium scoring, polygenic risk scores, and metabolic risk scores may...
Cardioprotective actions of nitroxyl donor Angeli's salt are preserved in the diabetic heart and vasculature in the face of nitric oxide resistance.
BRITISH JOURNAL OF PHARMACOLOGY - 01 Aug 2022
The risk of fatal cardiovascular events is increased in patients with type 2 diabetes mellitus (T2DM). A major contributor to poor prognosis is impaired nitric oxide (NO•) signalling at the level of tissue responsiveness, termed NO• resistance. This study aimed to determine if T2DM promotes NO• resistance in the heart and vasculature and whether tissue responsiveness to nitroxyl (HNO) is affect...
Breast arterial calcification and epicardial adipose tissue volume, but not density are independently associated with cardiovascular risk.
INTERNATIONAL JOURNAL OF CARDIOLOGY - 01 Aug 2022
Mammographically detected breast arterial calcification (BAC) has been proposed as surrogate marker for coronary artery disease (CAD) in women. Epicardial adipose tissue (EAT) and peri-coronary adipose tissue (PCAT) are inflammatory fat depots linked to atherogenesis. BAC has demonstrated association with inflammation, therefore we aimed to determine the association between BAC, EAT and PCAT.Si...

OBESITY REVIEWS : AN OFFICIAL JOURNAL OF THE INTERNATIONAL ASSOCIATION FOR THE STUDY OF OBESITY - 01 Aug 2022
Quality of life is a key outcome that is not rigorously measured in obesity treatment research due to the lack of standardization of patient-reported outcomes (PROs) and PRO measures (PROMs). The S.Q.O.T. initiative was founded to Standardize Quality of life measurement in Obesity Treatment. A first face-to-face, international, multidisciplinary consensus meeting was conducted to identify the k...
Cuffless blood pressure measuring devices: review and statement by the European Society of Hypertension Working Group on Blood Pressure Monitoring and Cardiovascular Variability.
JOURNAL OF HYPERTENSION - 01 Aug 2022
Many cuffless blood pressure (BP) measuring devices are currently on the market claiming that they provide accurate BP measurements. These technologies have considerable potential to improve the awareness, treatment, and management of hypertension. However, recent guidelines by the European Society of Hypertension do not recommend cuffless devices for the diagnosis and management of hypertensio...
Circulating short-chain fatty acids in hypertension: a reflection of various hypertensive phenotypes.
JOURNAL OF HYPERTENSION - 01 Aug 2022
Hypertension is the most common chronic condition globally, contributing to an increased risk of cardiovascular disease and premature death. Despite advances in treatment options, approximately 10% of patients have resistant hypertension, characterized by elevated blood pressure that does not respond to treatment. The gut microbiome is now increasingly recognized to play a role in the developme...

DIABETES RESEARCH AND CLINICAL PRACTICE - 01 Aug 2022
We evaluated the associations of age and duration of type 2 diabetes with major diabetes-related complications.We included 1.1 million people with type 2 diabetes from the Australian diabetes registry, followed from 2010 to 2019. We estimated the incidence of hospitalization or death from myocardial infarction (MI), stroke, and heart failure (HF), and hospitalisation for lower extremity amputat...
Diagnostic and Prognostic Value of Myocardial Work Indices for Identification of Cancer Therapy-Related Cardiotoxicity.
JACC. CARDIOVASCULAR IMAGING - 01 Aug 2022
Echocardiographic global longitudinal strain (GLS) is a useful measure for detection of cancer treatment-related cardiac dysfunction (CTRCD) but is influenced by blood pressure changes. This limitation may be overcome by assessment of myocardial work (MW), which incorporates blood pressure into the calculation.This work aims to determine whether myocardial work indices (MWIs) can help diagnose ...
Improving the Characterization of Stage A and B Heart Failure by Adding Global Longitudinal Strain.
JACC. CARDIOVASCULAR IMAGING - 01 Aug 2022
Current guidelines distinguish stage B heart failure (SBHF) (asymptomatic left ventricular [LV] dysfunction) from stage A heart failure (SAHF) (asymptomatic with heart failure [HF] risk factors) on the basis of myocardial infarction, LV remodeling (hypertrophy or reduced ejection fraction [EF]) or valvular disease. However, subclinical HF with preserved EF may not be identified with these crite...
Atrial Fibrillation and Stress: A 2-Way Street?
JACC. CLINICAL ELECTROPHYSIOLOGY - 01 Aug 2022
The accumulating literature linking stress with negative health outcomes, including cardiovascular disease (CVD), is extensively reported yet poorly defined. Stress is associated with a higher risk of hypertension, acute myocardial infarction, arrhythmogenesis, and heart failure. Stress mediates its effect through direct neuronal, endocrine, autonomic, and immune processes and indirectly by mod...
