What to Know About Diabetes and the Risk of Silent Heart Attacks
At first it seemed like a routine call—something the paramedics had dealt with countless times before. A man in his mid-50s was having a heart attack, and his physician had called for emergency support. But when the paramedics arrived, the physician pulled them aside and told them something peculiar: the man had no cardiovascular symptoms whatsoever. The man had come to his doctor’s office because he’d woken early the previous morning sweating and with a sharp pain in his left wrist. These symptoms had quickly subsided and he’d gone back to sleep. Later, after going about his day, he’d visited...

Johnson & Johnson Launches Heartline ™, the First-of-its-Kind, Virtual Study Designed to Explore if a New iPhone App and Apple Watch Can Help Reduce the Risk of Stroke
New Brunswick, NJ, February 25, 2020 — Johnson & Johnson (NYSE: JNJ) today announced that the Janssen Pharmaceutical Companies of Johnson & Johnson, in collaboration with Apple, opened enrollment for the Heartline™ Study. The study is designed to explore if the Heartline™ Study app on iPhone and heart health features on Apple Watch can improve health outcomes, including reducing the risk of stroke, with earlier detection of atrial fibrillation (AFib). AFib, a common form of irregular heart rhythm, is a leading cause of stroke in the U.S. To enroll in the Heartline™ Study, individuals must be age 65 or older...

Combination of Dexmedetomidine and Ketamine for Magnetic Resonance Imaging Sedation
Conclusions: The efficacy of DEX–KET sedation was comparable to that of midazolam for MRI examination. DEX–KET was related to shorter scan time and lower occurrence of complications compared to midazolam. Introduction Neurocritically ill patients often require brain magnetic resonance imaging (MRI) in addition to conventional neurological evaluations. Brain MRI can reveal structural lesions with a high sensitivity due to its excellent spatial resolution and enhanced soft tissue contrast (1–3). To acquire MRI images, patients' cooperation is imperative. However, keeping patients with ...

Asymptomatic Carotid Stenosis Is Associated With Circadian and Other Variability in Embolus Detection
Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this t...

Sickle Cell Disease Subjects Have a Distinct Abnormal Autonomic Phenotype Characterized by Peripheral Vasoconstriction With Blunted Cardiac Response to Head-Up Tilt
Conclusion We have shown that SCD subjects are much more likely than non-SCD subjects to have impaired cardiac, but intact peripheral responses to orthostatic stress induced by HUT. These abnormal responses are associated with low baseline cardiac parasympathetic activity, independent of hemoglobin level. The classification of autonomic phenotypes based on HUT response may have potential use for predicting disease severity, guiding and targeting treatments/interventions to alleviate the risk of adverse outcomes in SCD. Ethics Statement All experiments were conducted at Children’s Hospital Los Angeles (CHLA). The ...

YiQiFuMai Powder Injection Attenuates Coronary Artery Ligation-Induced Heart Failure Through Improving Mitochondrial Function via Regulating ROS Generation and CaMKII Signaling Pathways
This study was carried out in accordance with the recommendations of “Guide for the Care and Use of Laboratory Animals, National Institutes of Health.” The protocol was approved by the “China Pharmaceutical University.” Surgical Preparation The mice were anesthetized with chloral hydrate (4% chloral hydrate, ip). The HF model was induced by CAL as previously reported (Gao et al., 2010). Successful ligation of the coronary artery was confirmed by the occurrence of ST-segment elevation in electrocardiogram. Sham operated mice were performed the same process except left CAL. After ligation, the h...

Cardiovascular Programming During and After Diabetic Pregnancy: Role of Placental Dysfunction and IUGR
This study demonstrated that the incidence of ischemic heart disease and death were three times higher among men with low birth weight compared to men with high birth weight (5). Epidemiological investigations of adults born at the time of the Dutch famine between 1944 and 1945 revealed an association between maternal starvation and a low infant birth weight with a high incidence of hypertension and coronary heart disease in these adults (23). Furthermore, Painter et al. reported the incidence of early onset coronary heart disease among persons conceived during the Dutch famine (24). In that regard, Barker's findin...

Not Just Acid Reflux: The Need to Think Worst First
Discussion Heart disease is the leading cause of death in the United States.1 This year, 720,000 Americans will have a new coronary event—defined as first hospitalized myocardial infarction (MI) or coronary heart disease death—and around 335,000 will have a recurrent event. Approximately 35% of people who experience a coronary event in a given year and around 14% of patients who have an acute coronary syndrome will die from it.1 Roughly 60% of patients with an acute coronary syndrome are transported to the emergency department via ambulance.2–4. Up to one-third of patients experiencing an MI may not complain of chest...
