Background Incidental findings of coronary artery calcifications (CACs) are not consistently reported, and the clinical significance relating to cardiovascular outcomes remains to be established. In this single-center cross-sectional study, we assessed the association between incidental coronary artery calcification documented on formal chest CT reports and the incidence of major adverse cardiovascular events (MACE). Methods A MACE was defined as the occurrence of stroke or transient ischemic attack or ST-segment elevation myocardial infarction, non-ST-elevation myocardial infarction, or undergoing coronary artery bypass grafting.

August 2024

Division of Cardiovascular Medicine, Department of Medicine Henry Ford Health Detroit MI.

Article Synopsis
  • A meta-analysis was conducted to evaluate the effectiveness and safety of catheter-based renal denervation (RDN) in patients with uncontrolled hypertension, including those on and off antihypertensive medications.
  • The analysis included 15 randomized trials with a total of 2,581 patients, showing significant reductions in blood pressure for both groups, with larger decreases observed in those not taking medications.
  • RDN was found to be effective in lowering blood pressure while also demonstrating a good safety profile, confirming its potential as a treatment option for uncontrolled hypertension.

Article Synopsis
  • Industrialized environments, while offering benefits such as better education and lower infection rates, may contribute to brain atrophy, prompting a comparison of brain volume changes in industrialized versus non-industrialized populations.* -
  • The Tsimane and Moseten are two indigenous Bolivian groups studied, with the Tsimane showing increased brain volume in certain areas with age, while the UK Biobank participants experience a significant decrease in brain volume over time, particularly in frontal and temporal regions.* -
  • The findings suggest that lifestyle factors, including physical activity levels, may influence brain volume changes, with Tsimane males exhibiting surprising increases in some brain areas, while Tsimane females show greater decreases compared to UK Biobank females.*

Ethel Percy Andrus Gerontology Center, Leonard Davis School of Gerontology, University of Southern California, Los Angeles, CA 90089.

Article Synopsis
  • This study investigates brain aging and dementia in two indigenous South American populations, the Tsimane and Moseten, to understand brain volume (BV) changes in a nonindustrialized context.
  • It analyzes data from 1,165 individuals aged 40 to 94, revealing that BV declines with age but at a slower rate compared to industrialized populations.
  • The findings support the "embarrassment of riches" model, suggesting that a balanced energy intake during active lifestyles promotes better brain health, while excess body weight negatively impacts BV in modern societies.

The clinical implications of hypertension in addition to a high prevalence of both uncontrolled blood pressure and medication nonadherence promote interest in developing device-based approaches to hypertension treatment. The expansion of device-based therapies and ongoing clinical trials underscores the need for consistency in trial design, conduct, and definitions of clinical study elements to permit trial comparability and data poolability. Standardizing methods of blood pressure assessment, effectiveness measures beyond blood pressure alone, and safety outcomes are paramount.

The sternal foramen, usually an asymptomatic osteological defect, can lead to catastrophic consequences if not recognized prior to certain medical procedures. This study reports the prevalence of a sternal foramen in two South Amerindian populations compared with other published populations. We evaluated the presence of sternal foramina using thoracic computed tomography scans of 1334 (48% female) participants from two indigenous populations of Bolivia (n = 900 Tsimane, 434 Moseten).

Brain atrophy is correlated with risk of cognitive impairment, functional decline, and dementia. Despite a high infectious disease burden, Tsimane forager-horticulturists of Bolivia have the lowest prevalence of coronary atherosclerosis of any studied population and present few cardiovascular disease (CVD) risk factors despite a high burden of infections and therefore inflammation. This study (a) examines the statistical association between brain volume (BV) and age for Tsimane and (b) compares this association to that of 3 industrialized populations in the United States and Europe.

Background: Atrial fibrillation is the most common arrhythmia in post-industrialized populations. Older age, hypertension, obesity, chronic inflammation, and diabetes are significant atrial fibrillation risk factors, suggesting that modern urban environments may promote atrial fibrillation.

Objective: Here we assess atrial fibrillation prevalence and incidence among tropical horticulturalists of the Bolivian Amazon with high levels of physical activity, a lean diet, and minimal coronary atherosclerosis, but also high infectious disease burden and associated inflammation.

Acute chest pain is one of the most common presenting symptoms to the emergency department. Currently available risk scores are suboptimal in identifying low-risk patients eligible for early and safe discharge. Various, initially obtained clinical data have valuable discriminating power but are not being fully utilized.

Purpose: Renown Health (Reno, Nevada), a large, locally owned, not-for-profit integrated health care network, has developed an institution-wide policy to shift the treatment of deep vein thrombosis (DVT) from a short-acting anticoagulant and vitamin K antagonist to the direct oral anticoagulant rivaroxaban combined with pharmacy-directed follow-up at an outpatient anticoagulation clinic. We examined data on hospitalizations and costs pre-/post-policy change.

Methods: Data were obtained from the electronic health records of adults with newly diagnosed DVT treated at Renown Health.

BACKGROUND A coronary artery-left ventricular fistula is an anomalous communication between the coronary arteries and the cardiac chambers and is a rare congenital coronary anomaly that is often small and asymptomatic. Takotsubo cardiomyopathy, on the other hand, is a syndrome characterized by transient regional systolic dysfunction of the left ventricle, mimicking myocardial infarction, but in the absence of angiographic evidence of obstructive coronary artery disease or acute plaque rupture. We present the case of an elderly woman who presented with Takotsubo cardiomyopathy and who was incidentally discovered to have an associated coronary artery-left ventricular fistula.

Background: Conventional coronary artery disease risk factors might potentially explain at least 90% of the attributable risk of coronary artery disease. To better understand the association between the pre-industrial lifestyle and low prevalence of coronary artery disease risk factors, we examined the Tsimane, a Bolivian population living a subsistence lifestyle of hunting, gathering, fishing, and farming with few cardiovascular risk factors, but high infectious inflammatory burden.

Methods: We did a cross-sectional cohort study including all individuals who self-identified as Tsimane and who were aged 40 years or older.

To evaluate the effects of achieved systolic blood pressure (SBP) during treatment on cardiovascular (CV) outcomes, the authors measured event rates of a composite primary endpoint (CV death or nonfatal myocardial infarction or stroke) at on-treatment SBPs of ≥140 mm Hg and the 10 mm Hg intervals of <140 mm Hg, <130 mm Hg, and <120 mm Hg in 6459 patients with diabetes (mean age, 67) and 4246 patients without diabetes (mean age, 69) from the Avoiding Cardiovascular Events in Combination Therapy in Patients Living With Systolic Hypertension (ACCOMPLISH) trial. In the diabetic cohort, the primary endpoint was 49% lower (P<.001) at <140 mm Hg than at ≥140 mm Hg, and the separate components of this endpoint were also significantly reduced.
