Diabetes, heart disease together cause early death: Study

London: People suffering from both diabetes and heart disease are at a greater early death risk than people with just one condition or no disease, a study said.

After analysing more than 135,000 deaths that occurred during prolonged follow-up of almost 1.2 million participants, researchers from the University of Cambridge found that an individual in his/her 60s having both the conditions has an average reduction in life expectancy of about 15 years.

“A combination of diabetes and heart disease is associated with a substantially lower life expectancy,” said Emanuele Di Angelantonio from the department of public health and primary care in a paper that appeared in the journal of the American Medical Association.

At the age of 60 years, men with any two of the conditions would on average have 12 years of reduced life expectancy.

Men with three conditions – diabetes, stroke and heart attack (cardiometabolic diseases) – would have 14 years of reduced life expectancy. For women at the age of 60 years, the corresponding estimates were 13 years and 16 years of reduced life expectancy.

The figures were even more dramatic for patients at a younger age.

At the age of 40 years, men with all three cardio-metabolic conditions would on average have 23 years of reduced life expectancy and for women, the corresponding estimate was 20 years.

“Our results highlight the importance of preventing heart disease and stroke among patients with diabetes, and likewise averting diabetes amongst heart disease patients,” said professor John Danesh, study co-author.

Measures aimed at reducing diabetes and heart disease among this group could have a dramatic impact on their lives, the study said.

Excess Smoking Can Not Just Cause Cancer But Also Blindness

Heavy smokers also have reduced ability to discriminate contrasts and colours compared with non-smokers.

"Cigarette smoke consists of numerous compounds that are harmful, and it has been linked to a reduction in the thickness of layers in the brain, and to brain lesions, involving areas such as the frontal lobe, which plays a role in voluntary movement and control of thinking, and a decrease in activity in the area of the brain that processes vision," he said.

While excessive smoking has been linked to various health issues, including heart disease and cancer, a new study has warned that smoking over 20 cigarettes a day can cause blindness.

The study from the Rutgers University noted that chronic tobacco smoking can have harmful effects on “spatial and colour vision”.

The findings, published in the journal Psychiatry Research, noted significant changes in the smokers’ red-green and blue-yellow colour vision. This suggests that consuming substances with neurotoxic chemicals, such as those in cigarettes, may cause overall colour vision loss.

Heavy smokers also have reduced ability to discriminate contrasts and colours compared with non-smokers.

“Our results indicate excessive use of cigarettes, or chronic exposure to their compounds, affects visual discrimination, supporting the existence of overall deficits in visual processing with tobacco addiction,” said Steven Silverstein from the Rutgers’s Behavioral Health Care.

For the study, the team looked at 71 healthy people who smoked less than 15 cigarettes in their entire lives and 63 people, who smoked over 20 cigarettes a day. The participants were in the 25-45 year age group.

Previous studies had also pointed to long-term smoking as doubling the risk for age-related macular degeneration and as a factor causing lens yellowing and inflammation. (IANS)
