Diabetes Doubles Risk of Sudden Cardiac Death

Sudden cardiac death is what it sounds like. It’s often caused by a rhythm disturbance like ventricular tachycardia or ventricular fibrillation but can also be the result of a massive heart attack (acute blockage of blood flow to heart muscle).

I’m hopeful that good control of diabetes will reduce the risk of death.

“Diabetes mellitus was associated with a 2-fold increase in the risk of sudden cardiac death in the general population.”

Level of Fitness May Be More Important Than Number of Hours You Exercise

She can increase intensity by increasing the weight of those dumbbells

You’ve heard that “sitting is the new smoking,” right?

Regular physical activity prevents disease and prolongs life. But if you nevertheless still spend to much time sitting around either at work or home, the sitting tends to counteract the benefits of your exercise.

A new study says that your fitness level is more important for long-term health than the number of hours you exercise. Fitness level in this context was cardiorespiratory fitness, probably measured by a maximal-effort treadmill or bicycle test.

Some of your fitness level is inherited, but you can also improve your fitness with the proper intensity or duration of exercise. Rather than exercise longer, I prefer more intensity. Just strolling around the mall at 2 mph for two hours isn’t going to improve fitness in most folks.

From MNT:

The team conducted a cross-sectional study of 495 women and 379 men from Norway aged between 70-77 years. Sedentary time and physical activity were assessed by accelerometers, while cardiorespiratory fitness was determined by peak oxygen uptake (VO2 peak) – the measurement of the volume of oxygen that the body can utilize during physical exertion.

Researchers compared different levels of activity with fitness levels and cardiovascular risk factor clusters. A cardiovascular risk factor cluster was defined as the presence of three to five risk factors for heart disease.

These risk factors included: elevated waist circumference, elevated blood triglycerides or reduced “good” cholesterol levels, high blood pressure or treatment for hypertension, and elevated fasting blood sugar levels – combined symptoms commonly referred to as metabolic syndrome.

High cardiorespiratory fitness reduced risk of heart diseaseFindings – published in Mayo Clinic Proceedings – showed that when compared with women and men who were the least sedentary, women and men from the most sedentary group were 83 percent and 63 percent more likely to have cardiovascular risk factors from extended time sitting, respectively.

However, when the team took participants’ level of fitness into consideration – measured by having high age-specific cardiorespiratory fitness – they found that the fittest 40 percent had a decreased likelihood of cardiovascular risk factors from prolonged sitting.This finding held true even though the fittest participants spent between 12-13 hours per day sedentary and did not meet current moderate to vigorous physical activity guidelines.

Mediterranean Diet Could Prevent 20,000 Deaths Per Year in Britain

The Telegraph has the details:

“Some 20,000 lives could be saved each year if Britons switched to a Mediterranean diet, according to a new study.

The Medical Research Council (MRC) and Cambridge University followed nearly 24,000 people in the UK for up to 17 years to see how their diet affected the health of their heart.

They discovered that people who followed a diet high in fruits, vegetables, whole grains, nuts, fish and olive oil lowered their risk of cardiovascular disease by up to 16 per cent. The researchers estimate that 12.5 per cent of cardiovascular deaths, such as heart attacks and strokes,  could be prevented if everyone switched to the Mediterranean diet. There are around 160,000 heart deaths each year so 20,000 deaths could be avoided just by eating more healthy foods.”

I’ve been a proponent of the Mediterranean diet for over a decade. I’m not alone.

R.I.P., Mary Tyler Moore

Actress Mary Tyler Moore died today at the age of 80. She is probably the most famous type 1 diabetic of a certain generation, those watching TV in the 1960s and 1970s. According to her NYT obituary, her diabetes started in her 30s.

Average life expectancy in the U.S. is 78.8 years, based on 2014 data. It’s longer for women, shorter for men. That average is reduced by 10–12 years for those with type 1 diabetes.

It still amazes me that one of the very first users of insulin injections, Elizabeth Hughes, lived to be 73, having started insulin around age 22.

New research: Mediterranean diet linked to reduced risk of cardiovascular disease and death

This won’t surprise you if you’ve been reading this blog for a while:

“Heart disease is the leading cause of death for both men and women in the United States, killing around 610,000 people annually. Heart attack affects around 735,000 Americans each year, while around 800,000 people are affected by stroke.

Adopting a healthy diet is considered key for reducing the risk of CVD, and numerous studies have suggested the Mediterranean diet fits the bill.

A study published in the European Heart Journal earlier this year, for example, found older adults who adhered to the Mediterranean diet were at lower risk of heart attack, stroke, and cardiovascular death than those who followed a Western diet.”

Intensive Program Extended Lifespan By Eight Years in Type 2 Diabetes

"I don't mind dying. I just don't want to be there when it happens."  --Woody Allen

“I don’t mind dying. I just don’t want to be there when it happens.” –Woody Allen

MedPageToday has some details:

“Type-2 diabetics lived nearly 8 years longer when treated with an intensive, multifactorial approach that employed behavioral and pharmacological interventions.

The 160 patients with type-2 diabetes mellitus and microalbuminuria, now followed for 21 years, received either conventional or intensified therapy.

Thirty-eight intensive-therapy patients died during the follow-up period compared with 55 conventional-therapy patient deaths during the same time. This translated to a median survival period 7.9 years longer for the intensive-therapy cohort, as well as a median delay of 8.1 years to a first cardiovascular event, the investigators reported in the journal Diabetologia.

“The outcome of our study is very encouraging and emphasizes the need for early and intensified treatment of multiple modifiable risk factors for a poor prognosis of patients with type 2 diabetes,” said lead study author Peter Gaede, MD, of the University of Southern Denmark in Odense, in a statement.”

Study participants were northern Europeans (Danes) who had small amounts of protein (albumin) in their urine and were mostly in their 50s when this long-term study started.

Medical intervention included diet changes, drugs for diabetes/blood pressure/lipids, and exercise. Therapy for the intensive therapy group was “target-driven, with stepwise implementation of both behavioral and pharmacological treatment following a structured approach.”
