Intraoperative cone beam computed tomography-guided endovascular recanalization of an interrupted aorta
We report a case of real-time image-guided endovascular repair to highlight the value of preprocedural planning and intraprocedural cone beam computed tomography. Two-dimensional fluoroscopy enhanced with three-dimensional landmarks from cone beam computed tomography was used to direct a Nykanen radiofrequency wire (Baylis Medical, Montreal, Quebec, Canada) through the interruption, avoiding critical adjacent structures.

Mesenteric arteries from spontaneously hypertensive stroke prone rats exhibit an increase in NO-dependent vasorelaxation.
Abstract The endothelium is crucial for the maintenance of vascular tone by releasing several vasoactive substances, including nitric oxide (NO). Systemic mean arterial pressure (MAP) is primarily regulated by the resistance vasculature, which has been shown to exhibit increased vascular reactivity, and decreased vasorelaxation during hypertension. Here, we aimed to determine the mechanism for mesenteric artery vasorelaxation of the spontaneously hypertensive stroke-prone rat (SHRSP). We hypothesized that eNOS is up-regulated in SHRSP vessels, increasing NO production to compensate for the endothelial dysfunction....

The Divergent Cardiovascular Effects of ACE Inhibitors and ARBs in Patient With Type 2 Diabetes Mellitus
Publication date: Available online 22 December 2017 Source:Canadian Journal of Diabetes Author(s): Martin H. Strauss, Alistair S. Hall The renin angiotensin aldosterone system (RAAS) plays a central role in the pathophysiology of hypertension and vascular disease. Angiotensin-converting enzyme inhibitors (ACEi's) suppress angiotensin II (ANG II) concentrations, whereas angiotensin II type 1 (AT1) receptor blockers (ARBs) block the binding of ANG II to AT1 receptors. ACEi's and ARBs are both effective antihypertensive agents and produce similar risk reductions for stroke, a blood pressure-dependent phenomenon. ACEi's also ...

Mechanisms, Clinical Significance, and Prevention of Cognitive Impairment in Patients With Atrial Fibrillation
Publication date: December 2017 Source:Canadian Journal of Cardiology, Volume 33, Issue 12 Author(s): Lena Rivard, Paul Khairy Atrial fibrillation (AF) and dementia are major health issues, with growing evidence suggesting a consistent association between AF and all forms of dementia. Although dementia and AF share several risk factors, the association appears to be independent of a history of clinical stroke and other comorbidities such as hypertension, heart failure, and diabetes. Proposed mechanisms linking AF to cognitive decline include altered hemodynamics resulting in cerebral hypoperfusion, inflammation, genetic f...

Ambient Ozone Pollution and Daily Mortality: A Nationwide Study in 272 Chinese Cities
Conclusions: Our findings provide robust evidence of higher nonaccidental and cardiovascular mortality in association with short-term exposure to ambient ozone in China. https://doi.org/10.1289/EHP1849 Received: 4 March 2017 Revised: 3 October 2017 Accepted: 20 October 2017 Published: 21 November 2017 Address correspondence to H.

Long-term Fine Particulate Matter Exposure and Nonaccidental and Cause-specific Mortality in a Large National Cohort of Chinese Men
Conclusions: Long-term exposure to PM2.5 was associated with nonaccidental, CVD, lung cancer, and COPD mortality in China. The IER estimator may underestimate the excess relative risk of cause-specific mortality due to long-term exposure to PM2.5 over the exposure range experienced in China and other low- and middle-income countries. https://doi.org/10.1289/EHP1673 Received: 24 February 2017 Revised: 01 September 2017 Accepted: 05 September 2017 Published: 07 November 2017 Address correspondence to M.

Blood Pressure Lowering Targets in Patients with Diabetes Mellitus
Publication date: Available online 3 November 2017 Source:Canadian Journal of Cardiology Author(s): Alexander A. Leung, Raj S. Padwal Diabetes is a highly prevalent medical condition that commonly coexists with hypertension. The presence of diabetes and hypertension significantly increases the risk of adverse cardiovascular events. Although compelling evidence exists from randomized controlled trials demonstrating that blood pressure reduction effectively prevents cardiovascular complications, optimal blood pressure targets remain uncertain and continue to be the subject of ongoing controversy. Until recently, most major ...

Long-term Risk of a Seizure Disorder After Eclampsia.
CONCLUSION: Women with eclampsia should be reassured that, although the relative risk of a seizure disorder is higher than unaffected women, the absolute risk is extremely low (approximately one seizure/2,200 person-years). PMID: 29112665 [PubMed - as supplied by publisher]

Any type of physical exercise is good for the heart
Conclusion This study shows that all physical activity, in any form, is good for us. This includes both recreational and non-recreational activities. Don't be misled by some of the media: non-recreational activities like housework are not "better" than recreational activities like playing sports or going to the gym. The fact that reduced risk was seen with non-recreational activity across all countries, but only seen with recreational activity in high-income countries was probably just because fewer people in lower-income countries play sports or go to the gym. The researchers estimate that 8% of all deaths and...

Device used to close small hole in heart may protect against recurrent stroke
A device used to close a small hole in the heart may benefit certain stroke patients by providing an extra layer of protection for those facing years of ongoing stroke risk, according to the results of a large clinical trial led by UCLA researchers.“It is a major new treatment option for some people,” said Dr. Jeffrey Saver, director of theUCLA Comprehensive Stroke Center and lead author of the study. However, he added, “Using the device is going to have to be a considered clinical decision between the doctor and the patient about who’s the right person to get it.”Thefindings appear in the Sept. 14 New England Jo...

Atopic dermatitis and risk of hypertension, type 2 diabetes, myocardial infarction and stroke in a cross ‐sectional analysis from the Canadian Partnership for Tomorrow Project
ConclusionsWe did not find evidence of a positive association between AD and subsequent hypertension, T2D, MI or stroke; AD was inversely associated with these outcomes in our study. Given our findings and the conflicting literature, AD is likely not a major risk factor for cardiovascular disease.

Association of Long-Term Exposure to Transportation Noise and Traffic-Related Air Pollution with the Incidence of Diabetes: A Prospective Cohort Study
Conclusion: We found a positive association between residential transportation noise and diabetes, adding to the growing body of evidence that noise pollution exposure may be independently linked to metabolic health and should be considered when developing public health interventions. https://doi.org/10.1289/EHP1279 Received: 26 October 2016 Revised: 07 May 2017 Accepted: 09 May 2017 Published: 31 August 2017 Address correspondence to C.
