Blood sugar crash and cardiovascular health -

This risk might be further confounded by the development of impaired awareness of hypoglycemia, particularly in patients with coexisting CV autonomic neuropathy, a strong risk factor for sudden death. A recent analysis from ACCORD 44 confirmed that patients with baseline cardiac autonomic neuropathy were about twice as likely to die as patients without cardiac autonomic neuropathy.

The contribution of hypoglycemia to the increased mortality in the intensive study arm might be difficult to identify in large studies such as ACCORD. Death from a hypoglycemic event may be mistakenly ascribed to coronary heart disease, since there may not have been a preceding blood glucose measurement and since hypoglycemia cannot be detected postmortem.

In contrast to the ACCORD study, in VADT, a recent severe hypoglycemic event was an important predictor for CV death HR 3. William Duckworth and colleagues at the American Diabetes Association Scientific Sessions in in New Orleans, Louisiana. By contrast, in the ADVANCE study 5 , in which the overall occurrence of severe hypoglycemia was much lower than in ACCORD, no increase in all-cause or CV mortality was observed in patients randomized to the intensive arm.

Nevertheless, severe hypoglycemia was strongly associated with increased risks of various adverse clinical outcomes 45 , and the authors suggested that whereas severe hypoglycemia may contribute to these outcomes, it may alternatively be a marker of vulnerability to these events. Many patients with advanced diabetes and CVD undergo coronary revascularization.

Detailed findings about the impact of glycemic control on the outcome of the patients in that situation have not yet been reported in any of the three studies. Most guidelines recommend HbA 1c targets below 7. Because, according to a recent meta-analysis, the beneficial effect of strict glycemic control on CV events 47 seems to be limited for patients who are free from CVD, a less stringent glycemic target should be recommended for diabetic patients with longer duration of the disease, shorter life expectancy, advanced macrovascular complications, and chronic kidney disease and patients who are prone to hypoglycemia 46 , Accordingly, future diabetes guidelines will have to define a minimum HbA 1c value, especially for patients with longstanding diabetes or who have established CVD Indiscriminate application of intensive glucose-lowering therapy that could provoke dangerous hypoglycemia in frail elderly people with type 2 diabetes, or in patients with overt CVD, should be avoided.

This single-cell barrier between the blood and the rest of your body plays a number of important roles. For instance, this layer helps control what compounds move from the blood into the body, such as hormones. It also helps regulate the immune system.

Importantly, endothelial cells control vasoconstriction and vasodilation — how relaxed or constricted the blood vessels are. In this way, they control how much blood reaches any given part of the body — if the blood vessels constrict, less blood gets through and vice versa. During exercise, for instance, endothelial cells help the blood vessels in muscles to expand dilate , which moves more blood, oxygen, and glucose toward the muscles.

This plaque buildup is called atherosclerosis, and it narrows blood vessels, preventing blood from flowing freely around the body. Eventually, atherosclerosis can result in serious health conditions, including heart disease and stroke.

In this way, exaggerated blood sugar responses over the years may increase the risk of plaque formation and, consequently, the risk of heart disease.

There is also evidence that once plaques start forming, glucose spikes play a part in firming them up — which is a bad thing. The process, which is called glycation , happens when sugars stick to proteins. Over time, glycation produces advanced glycation endproducts AGE.

AGE are associated with diabetes, aging, and blood vessel dysfunction. They most often occur during times of inflammation and oxidative stress — more on both of those later.

So, blood sugar spikes are linked to heart disease, and it seems that plaques might play a part. But how might glucose be interfering with the endothelial cells?

Here, we meet reactive oxygen species ROS. These are reactive chemicals formed from oxygen. ROS are important for the day-to-day running of our cells.

However, as with many things in life, too much of a good thing can soon turn into a bad thing. So, your cells keep them finely balanced by producing antioxidants to counteract them. Now, back to the main story: Glucose spikes cause an increase in ROS. The increase in ROS leads to oxidative stress, which then impacts the endothelial cells.

This increases the risk that plaques will develop, and more plaque means a higher risk of heart disease. It is a healthy, life-saving reaction. As with many things in the body, such as glucose and ROS, it needs to be kept under control — too much inflammation over long periods damages the body.

Inflammation underpins many chronic diseases, including type 2 diabetes, some cancers, and heart disease. Glucose spikes also cause inflammation. In a small study , scientists artificially increased blood glucose levels in healthy participants.

When they analyzed their blood, they found increased levels of compounds associated with inflammation. In other words, ROS may be helping to drive this inflammation, too.

Sophia Antipolis, 07 January New research suggests that people who arrive at hospital emergency departments with acute heart failure should have their blood sugar levels checked on arrival.

This simple and inexpensive measure could identify patients at high risk of early death, further hospitalisations, or the development of more health problems, such as diabetes. Researchers from the Institute for Clinical Evaluative Sciences ICES , the Peter Munk Cardiac Centre at the University Health Network, and the University of Toronto, Canada, analysed the outcomes for 16, people who arrived at hospital emergency departments in Ontario, Canada, with acute heart failure between and The researchers compared the outcomes of the patients against a reference group of patients whose blood glucose levels ranged between 3.
