AIMS: Heart failure (HF) is associated with tissue hypoperfusion and congestion leading to organ dysfunction. Although cerebral blood flow (CBF) is preserved over a wide range of perfusion pressures in healthy subjects, it is impaired in end-stage HF. We aimed to compare CBF, autoregulation, and cognitive function in patients with mild non-ischaemic HF with healthy controls. METHODS AND RESULTS: Fifteen patients with mild idiopathic dilated cardiomyopathy and 15 matched healthy controls were studied...

Cardiac arrest is associated with high morbidity and mortality. Better-quality bystander cardiopulmonary resuscitation training, cardiocerebral resuscitation principles, and intensive post-resuscitation hospital care have improved survival. However, cognitive and functional impairment after cardiac arrest remain areas of concern. Research focus has shifted beyond prognostication in the immediate post-arrest period to identification of mechanisms for long-term brain injury and implementation of promising protocols to reduce neuronal injury...

Tanshinones are major bioactive diterpenoids of Salvia miltiorrhiza roots used for the treatment of cardiocerebral diseases. To develop effective elicitation and bioprocess strategies for the enhanced production of tanshinones, ultraviolet-B (UV-B) irradiation and methyl jasmonate (MeJA) elicitation were applied alone or in combination respectively in S. miltiorrhiza hairy root cultures. Our results showed 40-min UV-B irradiation at 40μW/cm(2) stimulated tanshinone production without any suppression of root growth, suggesting a new effective elicitor to S...

Sudden unexpected death in epilepsy (SUDEP) is defined as the abrupt, no traumatic, witnessed or unwitnessed death, occurring in benign circumstances, in an individual with epilepsy, with or without evidence for a seizure and excluding documented status epilepticus (seizure duration ≥ 30 min or seizures without recovery), and in which postmortem examination does not reveal a cause of death. Although the physiopathological mechanisms that underlie SUDEP remain to be clarified, the genetic background has been described to play a role in this disorder...

BACKGROUND AND OBJECTIVE: Isocorynoxeine (IC), a major alkaloid found in Uncaria rhynchophylla, exhibits wide beneficial effects on the cardiovascular and cardiocerebral vascular systems. Its metabolic pathway, however, has not been well studied yet. In this study, an ultra-high-performance liquid chromatography/quadrupole time-of-flight mass spectrometry (U-HPLC/Q-TOFMS) method was developed to investigate IC metabolism in plasma, urine and bile in rats given IC orally at 40 mg/kg. METHODS: Nine male Wistar rats were given IC 40 mg/kg orally...

BACKGROUND: Preoperative aspirin use within 5 days of cardiac operations is controversial. Aspirin could reduce cardiovascular complications and yet might increase risk of bleeding. Recent reports showed conflicting results, and whether aspirin has variable effects for different cardiac surgical procedures is unclear. METHODS: A single-center retrospective cohort analysis was performed. After propensity score matching (PSM) for identified confounders, the relationship between preoperative aspirin use and 30-day all-cause mortality, postoperative renal failure, major adverse cardiocerebral events (MACE), blood transfusion, reoperation for bleeding, and postoperative infection were estimated with separate logistic regression models...

Although improvement in cardiopulmonary resuscitation (CPR) performance and the increasing success at achieving return of spontaneous circulation (ROSC) have been possible in recent years, the survival and discharge rates of post-cardiac arrest (CA) patients remain disappointing. The high mortality rate is attributed to whole-body ischemia/reperfusion (I/R) induced multi-organ dysfunction that is well known as post-cardiac arrest syndrome. Post-cardiac arrest myocardial dysfunction and brain injury are the main clinical features of this complex pathophysiological process...

Out-of-hospital cardiac arrest (OHCA) is a major public health problem. In the United States, OHCA accounts for more premature deaths than any other cause. For over a half-century, the national "Guidelines" for resuscitation have recommended the same initial treatment of primary and secondary cardiac arrests. Using this approach, the overall survival of patients with OHCA, while quite variable, was generally very poor. One reason is that the etiologies of cardiac arrests are not all the same. The vast majority of nontraumatic OHCA in adults are due to a "primary" cardiac arrest, rather than secondary to respiratory arrest...

The previously published randomized trials of mechanical versus manual resuscitation of patients with cardiac arrest are inconclusive, but a recent systematic review concluded: "There is no evidence that mechanical cardiopulmonary resuscitation devices improve survival; to the contrary they may worsen neurological outcome." However, in our view, none of the randomized trials to date are definitive as the manual groups with primary cardiac arrest have not been treated optimally; that is, with minimally interrupted manual chest compressions, as advocated with cardiocerebral resuscitation...

Increasing evidence suggests that IL-1 β (C-511T) and IL-1 α (C-889T) genes polymorphisms are associated with the susceptibility to cardiocerebral vascular disease. In this paper, we investigated the relationships between these polymorphisms and the risk of ischemic stroke (IS) classified by TOAST criteria in the north Chinese Han population. 440 cases of IS and 486 age- and gender-matched controls of Chinese Han population were enrolled. Association study showed that the TT genotype and T allele of IL-1 α -889 C/T were significantly associated with IS of a large artery atherosclerosis (LAA) (TT: OR = 2...

Cardiac arrhythmias are associated with abnormal channel function due to mutations in ion channel genes. Epilepsy is a disorder of neuronal function also involving abnormal channel function. It is increasingly demonstrated that the etiologies of long QT syndrome and epilepsy may partly overlap. However, only a few genetic studies have addressed a possible link between cardiac and neural channelopathies. We describe a family showing the association between Brugada syndrome and epilepsy in which a known mutation in the SCN5A gene (p...

Out-of-hospital cardiac arrest (OHCA) is a common cause of death. In spite of recurring updates of guidelines, the survival of patients with OHCA was essentially unchanged from the mid 1970s to the mid 2000s, averaging 7.6% for all OHCA and 17.7% for OHCA due to ventricular fibrillation. In the past, changes in one's approach to resuscitation had to await the semi-decennial publications of guidelines. Following approved guidelines (at times based on consensus), survival rates of patients with OHCA were extremely variable, with only a few areas having good results...
