Dr Carolyn Lam:                Welcome to Circulation on the Run, your weekly podcast summary and backstage pass to the journal and its editors. I'm Dr. Carolyn Lam, associate editor from the National Heart Center and Duke National University of Singapore.                                                 What do salty, Chinese meals, neurotransmitters, cancer, and pulmonary arterial hypertension have in common? Well, you are not going to want to miss this week's feature discussion. It's going to reveal a new therapeutic approach to pulmonary arterial hypertension that may just surprise you, coming up right after these summaries.                                                 Do congenital heart defects signal a familial predisposition to cardiovascular disease? Well, this question was addressed in this week's first original paper from first and corresponding author, Dr. Auger, from University of Montreal Hospital Research Center in Quebec, Canada. Dr. Auger and colleagues aimed to determine whether the risk of cardiovascular disorders later in life was higher in women who had newborns with congenital heart defects. To answer the question, they studied a cohort of more than one million women who had delivered infants between 1989 and 2013 in Quebec. They showed for the first time that congenital heart defects in offspring were associated with increased risk of maternal cardiovascular morbidity later in life, including atherosclerotic disease, cardiac hospitalization, and cardiac transplantation. The association with subsequent cardiovascular morbidity risk was present for both critical and noncritical congenital heart defects. Thus, women who have given birth to offspring with congenital heart defects may benefit from early attention to traditional cardiovascular risk factors and more aggressive primary prevention strategies.                                                 Acute myocardial infarction, or AMI, is a major cardiovascular complication of non-cardiac surgery, but what are the outcomes following perioperative AMI? This question was answered in the next paper from co-corresponding authors, Dr. Smilowitz and Berger, from New York University School of Medicine. The authors identified more than 8,000 patients who were diagnosed with AMI during hospitalization for major non-cardiac surgery using the 2014 US Nationwide Readmission Database. They found that perioperative AMI after non-cardiac surgery was associated with a high in-hospital mortality and a 19% risk of 30-day hospital readmission among survivors. The majority of hospitalizations after perioperative AMI were because of infectious, cardiovascular, or bleeding complications. Recurrent AMI occurred in 11% of patients re-hospitalized after perioperative AMI. At six months after perioperative AMI, more than 36% of patients were re-hospitalized, and the overall risk of in-hospital deaths was almost 18%. Thus, hospital readmissions and mortality among patients with perioperative AMI pose a significant burden to the healthcare system. Strategies to improve outcomes of surgical patients early after perioperative AMI are warranted.                                                 What is the recent status of hypertension in China? Co-corresponding authors, Dr. Wang and Gao, from Fuwai Hospital, Peking Union Medical College, and Chinese Academy of Medical Sciences in China used a stratified, multistage, random sampling method to obtain a nationally representative sample of more than 450,000 residents from 31 provinces in mainland China from 2012 to 2015. The authors found that more than 23% of Chinese aged 18 years or old had hypertension, and that's equivalent to an estimated 284.5 million individuals. The prevalence of hypertension was similar in rural and urban settings, whereas three municipalities, mainly Beijing, Tianjin, and Shanghai had the highest prevalence of hypertension. Almost half the hypertensive population was aware of their hypertension. About 41% wer
