Men who live alone run a greater risk of dying prematurely after stroke

20.01.2015

Men who live alone have a considerably greater long-term risk of dying prematurely than other patients. This is shown in a doctoral thesis that followed 1,090 stroke cases in western Sweden.

As part of the Sahlgrenska Academy Study on Ischemic Stroke (SAHLSIS), Petra Redfors examined the long-term prognosis for 1,090 victims of ischemic stroke before the age of 70 and compared the results with 600 controls.

Excess mortality
According to her findings, 36% of patients who were living alone, as opposed to 17% of those with partners, died within 12 years after stroke. Among men, the gap widened to 44% vs. 14%.

Excess mortality associated with living alone was still found after adjusting for physical inactivity, high alcohol consumption, low educational level and other known risk factors.

“Among the conceivable causes are that people who live alone lead less healthy lives, are less prone to take their medication and tend to wait longer before going to the emergency room,” Dr. Redfors says. “For the healthy controls, excess mortality was also greater among men, particularly those living alone.”

Multiple risk
Etiology played a key role as well— having had a stroke due to large vessel disease, a blood clot from the heart or diabetes was an additional risk factor.

The thesis demonstrates that stroke victims faced 10 times as great a risk of recurrence within 12 years as healthy controls. The risk of myocardial infarction was twice as much.

“The pattern of excess mortality among people who live alone showed up here as well,” Dr. Redfors says. “Among the other risk factors for recurrence were the severity of the original event, along with diabetes or coronary artery disease. Physical inactivity increased the risk of cardiac infarction after stroke.”

Long-term cognitive loss
The thesis also found that a large percentage of stroke victims were still experiencing memory, concentration, cognitive and other loss at 7-year follow-up. Because many of them are of working age, the personal and social impact is enormous.

“Our results underscore the importance of intensive, long-term prevention among stroke patients, including medication for hypertension, diabetes and other underlying conditions, along with lifestyle changes,” Dr. Redfors says. “Above all, serious consideration needs to be given to providing greater support and more thorough information for patients who are living alone.”

The thesis Long-term Post-stroke Outcome – the Sahlgrenska Academy Study on Ischemic Stroke was defended on November 28.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
