Examining Heart Disease and Cholesterol with Fluorescence-Based Cholesterol Efflux Assays

Various studies have found out a negative correlation between cardiovascular disease and cellular cholesterol efflux. Reverse cholesterol transport (RCT) is a process by which the cholesterol efflux from peripheral cells and tissues occurs. RCT permits the extrahepatic cells, including macrophage-derived foam cells in arterial atherosclerotic plaque, to transfer excessive cholesterol back to the liver for bile acid synthesis and excretion, thereby decreasing the peripheral lipid burden.

			Postmenopausal women who suffer tooth loss are at higher risk of hypertension A new study in the American Journal of Hypertension indicates that postmenopausal women who have experienced tooth loss are at higher risk of developing high blood pressure. Multiple studies have suggested an association between periodontal disease and tooth loss with hypertension, but the relationship remains unclear.

			Improving blood vessel growth could help mitigate health problems arising from obesity New research led by York University's Faculty of Health shows that inhibiting a protein within blood vessels stimulates new blood vessel growth, resulting in healthier fat tissue and lower blood sugar levels.

	Green space linked to reduced risk of heart disease and stroke Researchers have shown that people who live in neighborhoods with denser greens paces may be at a lower risk of developing heart disease and stroke.

	Many people at risk of heart disease and stroke have excess abdominal fat Nearly two-thirds of people who are at high risk of cardiovascular disease and stroke have excess fat around the middle of the body (central obesity), according to findings from the European Society of Cardiology (ESC) EUROASPIRE V survey.

	People who eat red meat have high levels of chemical associated with heart disease, study finds Researchers have identified another reason to limit red meat consumption: high levels of a gut-generated chemical called trimethylamine N-oxide, that also is linked to heart disease.

	Women and men with heart attack symptoms receive different care from EMS Women are more likely than men to die of coronary heart disease, and past research has found that they are less likely to receive evidence-based therapies for heart attacks.

	Macrophage cells could help repair the heart following a heart attack, study finds Scientists at the Peter Munk Cardiac Centre have identified the type of cell key to helping the heart repair and potentially regenerate following a heart attack.

	Study: People living near oil and gas wells show early signs of cardiovascular disease Researchers at the Colorado School of Public Health have found a possible connection between the intensity of oil and gas exploration in an area and early indicators of cardiovascular disease among nearby residents.

	Weight history at ages 20 and 40 could help predict patients' future risk of heart failure In a medical records analysis of information gathered on more than 6,000 people, Johns Hopkins Medicine researchers conclude that simply asking older adult patients about their weight history at ages 20 and 40 could provide real value to clinicians in their efforts to predict patients' future risk of heart failure, heart attacks or strokes.

	Women with heart disease report more disparities in care compared with men Using data from a nationwide survey that represents 11 million women with heart and blood vessel diseases, Johns Hopkins Medicine researchers say women continue to report significant disparities in the care they receive compared with men.

	Formula of 80 and precautions can help prevent heart attack during festive season According to a new study, Christmas Eve is one of the most dangerous times of the year for the heart. It has indicated that a person’s risk for heart attack reaches its peak around late night a day before Christmas.
