Adults with varicose veins - gnarled, enlarged veins, most commonly appearing in the legs and feet - may be at increased risk of suffering from blood clot that could lead to vascular diseases, a study has found. The study found people with varicose veins were at a five times increased risk of developing a deep venous thrombosis (DVT) -- a clot in the legs which can lead to amputation or even death, the Daily Mail reported. They were twice as likely to develop a pulmonary embolism -- a clot which travels into the lungs and can be deadly.They also had double the risk of peripheral arterial disease, which reduces blood flow to the arms and legs. The study led by researchers including Pei-Chun Chen, adoctoral student from China Medical University in Taiwan, examined 212,984 patients aged 20 years and older with varicose veins, and a control group of equal patients without varicose veins. The results, published in the journal JAMA, showed that among adults diagnosed with varicose ...

“Vascular dementia ( VaD ) is characteristic of chronic brain ischemia and progressive memory decline, which has a high incidence in the elderly”, states the study. “However, there are no effective treatments for VaD, and the underlying mechanism of its pathogenesis remains unclear.” With that in mind, “This study investigated the effects of a synthetic  cannabinoid  receptor agonist WIN55,212-2 ( WIN ) on VaD, and molecular mechanisms of the effects.” Using a variety of tests conducted on rat models, it was found that  WIN55,212-2  – which is meant to mimic the effects of natural, cannabis-derived cannabinoids – “decreased the expression of Capase-3, and improved the learning and memory impairment of VaD rats.” Researchers state that “These data indicate that WIN exerts a neuroprotective effect on the cognitive deficits of VaD rats, which may be associated with the suppression of excessive  autophagy  and inflammation.”

Over 11 million Americans are at high risk of having a heart attack or  stroke  in the next 10 years — at least, that’s what the numbers say. The equation doctors use to estimate  cardiovascular  risk is prone to miscalculation, according to a new study, meaning patients may be popping daily aspirin or statins at the wrong dosage. The stakes are higher for African-Americans. With the old equation, 1 in 29 African-Americans may be incorrectly labeled very low or very high risk, according to the study. For example, a 46-year-old black man was estimated to have a 40 percent lower chance of having a heart attack or stroke than a white man of the same age and in identical health. In general, African-Americans are at higher risk of cardiovascular conditions than Caucasians, so miscalculations shouldn’t be taken lightly. The heart risk calculator transforms patient information — age, gender, race,  cholesterol  levels, blood pressure, prescriptions, a...

I recently learned that clinicians in the United States typically calculate this risk using a website or smartphone calculator based on equations approved by the federal government. Those numbers are also built into many electronic health records, so a patient’s risk is automatically calculated during an office visit. But the datasets used to come up with those calculations are decades old — some dating as far back as 70 years. That could leave as many as 11 million Americans at risk of taking the wrong dose of aspirin, statins and blood pressure medications, new research in the  Annals of Internal Medicine  suggests. “A lot has changed in terms of diets, environments and medical treatment since the 1940s,” Stanford primary care physician and  epidemiologist  Sanjay Basu, MD, senior author of the study, said in a Stanford Medicine press release. “So, relying on our grandparents’ data to make our treatment choices is probably not th...

By probing the effect that vitamin D-3 has on the cells that make up the lining of blood vessels, scientists at Ohio University in Athens, OH, have identified for the first time the role that the “sunshine vitamin” plays in preserving  cardiovascular  health. In a paper published in the International Journal of  Nanomedicine , they describe how they used nanosensors and a cell model to identify the molecular mechanisms that vitamin D-3 can trigger in the  endothelium , which is the thin layer of tissue that lines blood vessels. It was previously believed that the endothelium served no other purpose than to act as an inert “wrapper” of the vascular system, allowing both water and electrolytes to pass in and out of the bloodstream. However, advances over the past 30 years have revealed that the endothelium acts more like an organ that lines the whole of the circulatory system from the “heart to the smallest capillaries,” and who...

Red blood cell (RBC) transfusions during surgery are associated with double the risk of venous  thromboembolism  (VTE) over the ensuing 30 days, researchers reported in JAMA Surgery. Investigators analyzed more than 750,000 patients undergoing surgery from a registry containing 525 North American hospitals. A total of 6.3 percent of the patients received perioperative RBC transfusions, defined as a transfusion from 72 hours before to 72 hours after surgery. These patients experienced VTE at a rate 2.1 times higher than those who didn’t undergo transfusions, even after adjustment for patient characteristics, surgical complexity and hospital length of stay. However, only 0.8 percent of patients in the study experienced postoperative VTE, a combination of  pulmonary  embolism and deep vein thrombosis. “Transfused RBCs have been proposed to modulate the inflammatory cascade,” wrote lead author Ruchika Goel, MD, MPH, with New York Presbyterian Hospital and We...

Peripheral Vascular Disease is a serious condition that often reveals itself through pain in the legs or other extremities. Often called  Peripheral  Artery Disease or Peripheral  Arterial  Disease (PAD), it is the result of arteriosclerosis or restricted blood flow caused by a buildup of plaque on the inner walls of the  arteries . When the flow of blood is limited, limbs, the heart and brain are  deprived  of the oxygen. Additionally, muscle cells in the wall of the artery overgrow and fat and calcium build up within these irregular spaces. Bleeding into the artery wall can also occur resulting in formation of a clot, which narrows the opening of the blood vessel even further.

A group of Danish scientists- cardiologists  from the University of Copenhagen came to the conclusion that the likelihood of early death from problems with the blood vessels for men is doubled if they lead a solitary existence. The results of their study they presented at the EuroHeartCare Congress in 2018 in Dublin. Many experts believe that loneliness in terms of the risk of such illnesses as coronary heart disease and stroke even more dangerous in its effects than obesity. Danish researchers have added to this conclusion that loneliness can also increase the likelihood of other cardiac disorders such as  ischemia , atrial fibrillation. Preliminary research, incidentally, also showed that loneliness can be a factor of premature death. Data showed: people without relatives, family and loved ones often die several years earlier than their peers, sharing your life with someone else. “Loneliness and at the same time affects the health in itself, and leads to the fact tha...

Blood pressure in midlife that was higher than normal — but below the threshold used to treat  hypertension  in some countries — was linked to increased risk of developing dementia later in life, an analysis of the long-running Whitehall II study found. Men and women who had a systolic blood pressure ≥130 mm Hg at age 50 had a 45% greater risk of developing dementia than people with a lower systolic blood pressure at the same age, reported Archana Singh-Manoux, PhD, of the French National Institute of Health and Medical Research (INSERM) in Paris, and colleagues in  European Heart Journal. This association was not seen at ages 60 or 70. “Our analysis suggests that the importance of midlife hypertension on brain health is due to the duration of exposure,” Singh-Manoux said in a statement. “So we see an increased risk for people with raised blood pressure at age 50, but not 60 or 70, because those with hypertension at age 50 are likely to be exposed to thi...

Buerger’s disease is a condition wherein the blood flow to the arteries is restricted due to the constant use of tobacco. Continuous smoking leads to peripheral vascular disease, loss of tissue and in major cases, amputations of the limbs explains vascular surgeon Dr S. Bala Kumar. Buerger’s disease is chronic, inflammatory, obstructing tobacco-associated vasculopathy found in small and medium-sized arteries. It is largely found in young smokers. The flow of blood supply to the arteries and adjacent nerves is affected due to constant use of tobacco products like cigarettes, cigars and beedis. Acute cases of Buerger’s disease result in tissue loss and major amputations of limbs. The incidence in India is between 77 per cent in males and 11 to 23 per cent in females. The median age of diagnosis is 34 years. This disease is a relatively common cause of peripheral vascular disease in young people and a cause of disability in patients of all ages. It manifests with decreased blood...

Therapies targeting cholesterol and inflammation have both shown the ability to reduce  cardiovascular  events among patients with atherosclerosis, but more evidence is needed before anti-inflammatory drugs gain widespread use similar to statins, according to a consensus statement published May 14 in the European Journal of Preventive Cardiology. The statement—authored by the European Society of Cardiology’s working group on atherosclerosis and  vascular biology —was catalyzed by the results of the recently published CANTOS trial. This study showed the anti-inflammatory drug canakinumab cut the risk of subsequent cardiac events in heart attack survivors, even when LDL cholesterol levels weren’t significantly lowered. “Although the results of the CANTOS trial can be considered a milestone in cardiovascular medicine, canakinumab prescription for patients with cardiovascular risk to improve their prognosis needs to overcome certain hurdles,” wrote t...

researchers have developed an analytical imaging technology based on functional MRI for detecting and monitoring cerebral vascular disorders and injuries that does not require the use of contrast agents. The new imaging method focuses on tracking an intrinsic blood-related MRI signal, which has been shown to travel with the blood. The signal is used as a natural biomarker to assess blood flow in a patient. “We can compare the signal from symmetric arteries and veins in both hemispheres or neck to assess the cerebrovascular integrity or the balance of blood flow,” said Yunjie Tong, an assistant professor in Purdue’s Weldon School of Biomedical Engineering, who developed the technology along with Blaise Frederick, a biophysicist and associate professor at Harvard Medical School. “The blood flow should be symmetric between the two sides in a healthy subject.” The time delay between the intrinsic signals from the internal carotid artery and the internal jugular vein represents the...

DEMENTIA signs and symptoms appear when someone’s mental ability begins to decline. Types of the condition include vascular dementia and dementia with lewy bodies. Trying out a particular exercise could be the best way to reduce your risk of developing the condition. Dementia  signs and symptoms include memory loss, a poor ability to concentrate and getting confused in familiar places. Types of the condition include vascular dementia,  Alzheimer's disease dementia with lewy bodies. Your risk of developing the condition increases as you get older.You may be able to reduce this, however, if you change your lifestyle and diet to start doing certain exercises.Doing some brisk walking for 150 minutes a week could help reduce your risk of developing the condition, according to the Alzheimer’s Society. Doing exercise can reduce your risk of dementia, but may not help if you’re already suffering from the condition. A study recently published in the British Medical Journ...

DEMENTIA is a term used to describe different types of brain degeneration. The most common type of dementia is Alzheimer’s Disease, although vascular dementia and dementia with lewy bodies are also types. Symptoms of dementia include leaving items in the wrong place and memory loss. New research has found that changes in yellow spots under the eye could be a way to monitor dementia progress Dementia types include vascular dementia, and dementia with lewy bodies, although Alzheimer’s disease is the most common. Signs and symptoms of dementia can include memory loss, being unable to follow conversations or getting lost in familiar places. Early warning signs of dementia include asking the same question repeatedly and getting up in the night. Studying over 110 people, the researchers scanned their eyes at the beginning of the test and after two years. They found that the change in the number of hard drusen formations, or yellow spots, on the retina was associated with the stage of d...

A laser technique that uses pulses of infrared light to blast channels into the heart muscle has long been the last hope for patients whose arteries are so clogged and constricted that they cannot benefit from bypass surgery. The technique, called transmyocardial laser revascularization, or TMR, has remained a niche procedure for 20 years, practiced only on patients with no other options. In transmyocardial laser revascularization, lasers vaporize a tube of heart muscle and injure a zone of heart tissue surrounding that tube, causing either new blood vessels to develop or denervation. Courtesy of CryoLife. But recent advances in stem cell research have inspired a new dimension to TMR therapy. Following up on promising research done in Europe, planned studies in the US will combine TMR with stem cells to spur new blood vessel growthat tube, causing either new blood vessels to develop or denervation.
