Going from Primary to Primordial Prevention: Is the Juice Worth the Squeeze?

PURPOSE OF REVIEW: While primary prevention strategies target individuals who are at high risk of cardiovascular disease, there is rising interest towards primordial prevention that focuses on preventing the development of risk factors upstream of disease detection. Therefore, we review the advantages of primordial prevention interventions on minimizing future cardiovascular events. RECENT FINDINGS: Primordial prevention of atherosclerotic cardiovascular disease involves behavioral, genetic, and environmental strategies, starting from fetal/infant health and continuing throughout childhood and young adulthood. Early interventions focusing on modifiable risk factors such as physical inactivity, non-ideal body weight, smoking, and environmental pollutants are important towards preventing the initial occurrence of risk factors such as hypertension, dyslipidemia, and diabetes to ultimately reduce cardiovascular disease. Implementing primordial prevention strategies early on in life can minimize cardiovascular events and lead to healthy aging in the population. Future studies can further evaluate the effectiveness of various primordial prevention strategies.

Artificial intelligence coronary computed tomography, coronary computed tomography angiography using fractional flow reserve, and physician visual interpretation in the per-vessel prediction of abnormal invasive adenosine fractional flow reserve.

Aims: A comparison of diagnostic performance comparing AI-QCTISCHEMIA, coronary computed tomography angiography using fractional flow reserve (CT-FFR), and physician visual interpretation on the prediction of invasive adenosine FFR have not been evaluated. Furthermore, the coronary plaque characteristics impacting these tests have not been assessed. Methods and results: In a single centre, 43-month retrospective review of 442 patients referred for coronary computed tomography angiography and CT-FFR, 44 patients with CT-FFR had 54 vessels assessed using intracoronary adenosine FFR within 60 days. A comparison of the diagnostic performance among these three techniques for the prediction of FFR ≤ 0.80 was reported. The mean age of the study population was 65 years, 76.9% were male, and the median coronary artery calcium was 654. When analysing the per-vessel ischaemia prediction, AI-QCTISCHEMIA had greater specificity, positive predictive value (PPV), diagnostic accuracy, and area under the curve (AUC) vs. CT-FFR and physician visual interpretation CAD-RADS. The AUC for AI-QCTISCHEMIA was 0.91 vs. 0.76 for CT-FFR and 0.62 for CAD-RADS ≥ 3. Plaque characteristics that were different in false positive vs. true positive cases for AI-QCTISCHEMIA were max stenosis diameter % (54% vs. 67%, P < 0.01); for CT-FFR were maximum stenosis diameter % (40% vs. 65%, P < 0.001), total non-calcified plaque (9% vs. 13%, P < 0.01); and for physician visual interpretation CAD-RADS ≥ 3 were total non-calcified plaque (8% vs. 12%, P < 0.01), lumen volume (681 vs. 510 mm3, P = 0.02), maximum stenosis diameter % (40% vs. 62%, P < 0.001), total plaque (19% vs. 33%, P = 0.002), and total calcified plaque (11% vs. 22%, P = 0.003). Conclusion: Regarding per-vessel prediction of FFR ≤ 0.8, AI-QCTISCHEMIA revealed greater specificity, PPV, accuracy, and AUC vs. CT-FFR and physician visual interpretation CAD-RADS ≥ 3.

Natural Supplements for COVID19-Background, Rationale, and Clinical Trials.

Worldwide, the turmoil of the SARS-CoV-2 (COVID-19) pandemic has generated a burst of research efforts in search of effective prevention and treatment modalities. Current recommendations on natural supplements arise from mostly anecdotal evidence in other viral infections and expert opinion, and many clinical trials are ongoing. Here the authors review the evidence and rationale for the use of natural supplements for prevention and treatment of COVID-19, including those with potential benefit and those with potential harms. Specifically, the authors review probiotics, dietary patterns, micronutrients, antioxidants, polyphenols, melatonin, and cannabinoids. Authors critically evaluated and summarized the biomedical literature published in peer-reviewed journals, preprint servers, and current guidelines recommended by expert scientific governing bodies. Ongoing and future trials registered on clinicaltrials.gov were also recorded, appraised, and considered in conjunction with the literature findings. In light of the controversial issues surrounding the manufacturing and marketing of natural supplements and limited scientific evidence available, the authors assessed the available data and present this review to equip clinicians with the necessary information regarding the evidence for and potential harms of usage to promote open discussions with patients who are considering dietary supplements to prevent and treat COVID-19.

Vasoactive intestinal peptide producing pheochromocytoma and intracardiac thrombosis.

A case of pheochromocytoma producing vasoactive intestinal peptide (VIP) and left ventricular thrombus in the absence of cardiomyopathy or wall motion abnormalities on echocardiogram is presented along with a review of the relevant literature. A 30-year-old female of Afghani descent with past medical history of panic attacks presented with fever, cough, sore throat, vomiting, and was found to have an 11 cm adrenal mass consistent with primary adrenocortical adenoma versus carcinoma. Her tumor elicited catechols and vasoactive intestinal peptide. Her hospitalization was complicated by left ventricular thrombosis leading to an embolic injury to her right kidney, respiratory failure, need for transient dialysis and urinary tract infections. She developed a profuse secretory diarrhea and decision was made to treat with empiric octreotide infusion and imodium with improvement in symptoms. She underwent coil and particle embolization followed by resection. Followup PET gallium scan showed no evidence of residual disease or metastasis. VIP producing pheochromocytoma associated with intracardiac thrombosis is rare. Outcomes depend on prompt diagnosis of the pheochromocytoma and multidisciplinary approach to management.

Cardiac birth defects in a twin infant born to a woman with chronic myeloid leukemia on dasatinib.

Preclinical animal studies have demonstrated an association between maternal use of tyrosine kinase inhibitors and embryofetal toxicity; yet, multiple clinical case series have reported normal pregnancy outcomes and healthy infants in women on these medications during the course of their pregnancy. We describe a case of a woman with chronic myeloid leukemia who had taken the second-generation tyrosine kinase inhibitor dasatinib during the first 12 weeks of her dichorionic diamniotic twin pregnancy and subsequently delivered two low-birth weight infants, one with severe cardiac malformations and the other without apparent birth abnormalities. To our knowledge, this is the first reported case of fetal cardiovascular defects in an infant born to a woman on dasatinib during a twin pregnancy and supports current recommendations to avoid this medication during pregnancy. We also review relevant preclinical and clinical studies of tyrosine kinase inhibitor use during pregnancy and explore alternative therapeutic options for patients with chronic myeloid leukemia during pregnancy to aid clinicians in the appropriate management of these patients so as to minimize both maternal and fetal risks.
