Nerves are required to repair the injured heart
Cardiovascular diseases (CVD), such as heart attack, are responsible for approximately 18 million deaths each year, which accounts for more than 30% of all deaths worldwide. CVD is the single greatest cause of death in humans killing
在cli评价心率测量nical studies – Which way to do it right?
100.000 times a day – this is the daily number of heart beats in human beings. This huge workload normally will pass by unobserved in a healthy being, but in a patient with heart disease any alteration
Lymphatic drainage of the heart
Someone once said that each man is his own island. I would make the analogy that our body is a country, where each organ is a city, each cell a building or factory in the city, and
Jurassic siphon
The sauropod dinosaurs were the tallest animals to ever stalk the earth. The fossilised remains of sauropods indicate that some had necks as long as 12 m. Sauropods are often depicted with their heads held high –
Infections in right-sided heart valves often leave doctors with no right answer
A normal human heart has four chambers and four valves. When these valves are working well, they stop blood from flowing backwards and are essential to good heart function. Two valves are in the right side of
Coronary ostoplasty for congenital atresia of the left main coronary artery ostium in a teenage boy
Coronary artery abnormalities are reported as the third largest cause of sudden death in young athletes. Because patients usually do not have any apparent abnormality on medical examination, it is difficult to detect this before some events.
心defects before birth: Why are most cases still being missed (and what can we do about it)
心defects occur in roughly 1 in 100 live births—far more than any other kind of birth defect. Over the past decade, it has become increasingly clear that babies with major forms of heart disease have must
Obesity enhances the risk of arrhythmia
The heart consists of 4 chambers in mammals. The upper two chambers are atria, and the lower ones are ventricles. Ventricles work as pump to eject blood to whole body. Atria have 2 important roles: 1) to
A better way to measure heart disease risk for an overweight society
Low density lipoprotein (LDL) cholesterol or the “bad cholesterol” is an established measure of cardiovascular risk. LDL particles interact with the lining of the blood vessel and contribute to cholesterol loading in the arterial wall. Continued buildup
Fighting chronic rejection of transplanted organs
In many diseases the only available cure is organ transplantation. However, if the transplanted organ does not derive from an identical twin (which is genetically identical to the recipient) it becomes rejected by the immune system of
The heart’s own acetylcholine important in health and disease
Tissues and organs of our body are under the control of active chemical compounds. Hormons are released from endocrine glands and reach the targets with blood. Transmitters are released from the endings of nerve fibers. If the
Melatonin reduces blood pressure and tunes up disrupted circadian rhythms in the seniors
The older we get the more likely our circadian rhythms are disrupted. For example, blood pressure not only tends to increase but as well become more irregular. Luckily, as we show here, melatonin helps to ameliorate both
A transcriptomic approach for cardiac (heart) safety assessment
New drug discovery relies on several phases of safety assessment. One such prominent in vitro safety assessment assay is the “hERG potassium channel assay” for cardiac safety. If a compound blocks the hERG potassium channel in a
心and blood pressure adverse effects of phenytoin
Phenytoin is an effective antiepileptic drug which is used for many years in the treatment of epileptic seizures. Whereas its oral form is used for the long-term treatment of epilepsy, the intravenous form – the injection into
New MRI method for patients with fast and irregular heartbeats
Magnetic resonance imaging (MRI) takes very detailed pictures of the heart. MRI is very safe because it does not give patients harmful x-rays and is one of the best hospital tests used by doctors to check how
Prognostic value of trans-thoracic echocardiography in patients with acute stroke and atrial fibrillation
Currently, ischemic stroke (which occurs when a blood vessel carrying blood to the brain is blocked) in patients with atrial fibrillation (AF), an abnormal heart rhythm characterized by rapid and irregular beating, can be successfully prevented with
The use of multisite ultrasound in cardiac arrest – the SESAME-protocol
Cardiac arrest is the most critical emergency. The sudden interruption of oxygen supply damages the brain after some minutes. Finding a cause for efficiently fixing the problem is the main target of the frontline physician. Ultrasound is
HDL cholesterol: sometimes more is not necessarily better
Lipoproteins are complex particles that are responsible for transporting the water insoluble molecule, cholesterol, through the blood stream. Cholesterol is transported from the liver to peripheral tissues. Excess cholesterol in low-density lipoprotein (LDL) is deposited in the
心disease in cancer patients (onco-cardiology / cardio-oncology)
In the United States, heart disease and cancer have been the 2 leading causes of death from 1935 through 2013. In 2010, both diseases accounted for almost half of all deaths in the U.S. Notwithstanding, much success
Secret of cardiovascular diseases (CVDs) hidden in small molecules
Diagnosis and treatment of cardiovascular diseases (CVDs) are a great challenge for today’s medicine. It also results from not fully explained pathomechanisms underlying their development and progression. The group of CVDs is a very complex mixture of
