The investigators compared resting heart rate and heart rate variability – – the beat-to-beat variation in heart rate – – with the ability to perform basic day to day activities such as grooming, using and walking the toilet. They looked at more complicated tasks such as for example doing housework also, shopping and taking medications as prescribed. Over the average follow-up of 3 years, seniors with the best resting heartrate had a nearly 80 % increased risk of decline in their capability to do basic day to day activities, and a 35 % increased threat of decline in their ability to do more difficult daily tasks.The stent platform was the ISAR stent with a tough surface, the value which has been founded by many previous studies. A designed rough surface may raise the drug-storing capacity of stents specifically. All individuals received dual-antiplatelet therapy with ASA and clopidogrel for a minimum of six months, were scheduled for a re-angiography at 6-8 months and were contacted at 30 days and at one year for the assessment of the clinical status. Patients with ST-elevation myocardial infarction , cardiogenic shock or a left main disease had been excluded from the trial.
