People in there 80s and 90s are more likely to develop acute coronary syndrome than their younger counterparts. Despite this, they receive less therapy and diagnostic procedures. A doctoral thesis at Sahlgrenska Academy has explored the topic.
Previous studies have shown that older patients are less likely to receive the most evidence-based, recommended treatment for acute coronary syndrome. Regarding the elderly, quality and quantity of the underlying scientific evidence is limited.

A number of recent studies by researchers at Sahlgrenska Academy have included more than 45,000 elderly cardiac patients. Presented in Dr. Berglind Libungan's doctoral thesis, the studies found that treatment of patients with symptoms of acute coronary syndrome, to some extent, is age-related.
• Although patients with chest pain in their 80s and 90s are more likely to have a final diagnosis of acute coronary syndrome, they do less angiograms, echocardiograms and receive less medical therapy compared with their younger counterparts. However, there was not a delay to hospitalization or therapy when compared to younger patients.
"I presume that older patients receive less evidence-based treatment because the treating physician feels that the risks outweigh the benefits," Dr. Libungan says.
• The risk for death, among older patients with myocardial infarction who are treated with medical therapy, is higher than among patients who do an intervention, coronary angioplasty.
"Given the major differences between various patient groups, this finding does not mean that interventions are automatically better," Dr. Libungan says. “Patients who are treated with medication alone are usually older and in poorer health. Additional clinical research is needed to determine the strategy that works best for older patients.”
• The number of elderly Swedes with myocardial infarction treated with balloon angioplasty has increased over the past decade. Even though they are generally older and sicker, the risk for complications has not increased.
"The evidence suggests that more elderly patients could be offered balloon angioplasty," Dr. Libungan says.
Higher mortality rate
The new studies have also found that elderly patients who suffer cardiac arrest have a higher mortality rate which increases with age. The survival rate is 6.6% among 70-80 year-olds, 4.4% among 80-90 year-olds and 2.3% among those older than 90.
Mr. Libungan will defend his thesis, "Acute coronary syndrome and cardiac arrest in the elderly" on May 28.

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.
Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...
In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
