This is a good and pragmatic question. Just to give some insight, the benefits of aspirin in high risk patients (with acute or previous vascular disease or some other predisposing condition) are explicitly shown. I recommend reading the freely available meta-analysis published in BMJ in 2002. Naturally, the patients without any disease or predisposing ...

Heart attacks are caused by reduced or blocked blood flow to the heart, but a sphygmonanometer cuts off the blood flow to the arm (or leg) only. It's not possible it could cause a heart attack directly even if it were left on indefinitely. However, leaving a BP cuff on for a very long time could cause injury and eventual tissue death in the arm, or possibly ...

Yes, or at least, that's what this article in a reputable medical journal says and there is no reason to be more skeptical of it than the normal skepticism that any isolated article deserves. The 10 year IRR they find is 0.04 (95% CI 0.01-0.36), after adjusting for age and BMI, which is a pretty strong effect. The article is not claiming this is the best or ...

This connection has been reported by several groups, in credible journals (I left a few references below). The study and news article you are referring to is confirming earlier findings, it is not the first to report this. In the examples I've seen, the studies rely on large datasets, for example, incidences in an entire country, in order to show a ...

The NHS page you linked to does quite a good job of explaining why the study that puts forward the claim that there isn't a link doesn't actually quite say that with any degree of certainty. They are a bit wishy-washy about it and the British Heart Foundation takes a somewhat tougher stance LDL cholesterol (LDL-C), along with other types of cholesterol are ...

The mentioned paper has been published in BMJ Open in 2015: The Association Between Low-Density Lipoprotein Cholesterol and Mortality in the Elderly. A systematic review. The NHS article mentions the limitations of the review: only participants older than 60 years were included, only LDL (but not HDL) cholesterol was investigated, the effect of statins (...

Yes, blood viscosity changes with altitude. This is a study in rats where the control group was kept at normal altitude and the test group at simulated 5500 meters. Besides, RBC counts, hematocrit, whole blood viscosity, erythrocyte aggregation index of hypoxia model rats were all notably higher than those of normal control rats respectively. Changes ...

Limitations of the study:(3) First, the study assessed the association between push-ups and CVD events. The results do not support push-up capacity as an independent predictor of CVD risk.  Second, because the study cohort consisted of middle-aged, occupationally active men, the study results may not be generalizable to women, older or nonactive persons, ...

By definition, cardiac arrest means the heart is not pumping blood; therefore, there is no blood pressure. None at all. So if you were to cut a person in cardiac arrest, they would not bleed. If a heartbeat can be restored, the findings after cardiac arrest will vary. In general, if a normal heartbeat can be restored and the heart is once again pumping ...

Following were independent risk factors found in the large Interheart study (http://www.thelancet.com/journals/lancet/article/PIIS0140-6736%2804%2917018-9/abstract): 1. Smoking 2. Diabetes 3. High blood lipid levels 4. High blood pressure 5. Abdominal obesity 6. Psychosocial stress 7. Lack of regular physical exercise 8. Lack of regular fruits and ...

There are three types of heart attacks: unstable angina pectoris, non-ST-elevation myocardial infarct (NSTEMI) and ST-elevation myocardial infarct (STEMI). Choosing between thrombolysis and angioplasty matters only in the STEMI. Which is better: thrombolysis (treatment with clot busting medication) or primary angioplasty (an invasive procedure for ...

A number of studies have shown that in early period (within 2-3 hours of onset of chest pain), thrombolysis is as good or even better than primary angioplasty: FAST-MI study USIC 2000 registry CAPTIM trial and its 5 year results Vienna registry PRAGUE-2 study STREAM trial DANAMI-2 study Subgroup analysis of this study quoted by arkiaamu also showed clear ...

The Society of Cardiovascular Angiography and Interventions has an excellent summary of the types of heart attacks on their web site. As you can see, the first type, STEMI, is generally due to blockages, but the other types are due only to partial blockages or no blockage at all. He probably suffered one of the types of events other than a STEMI heart ...

According to the literature, risk factors for chronic lymphocytic leukaemia (CLL) are: gender: CLL is more frequent in men than in women age: CLL is considered to be mainly a disease of older adults, with a median age at diagnosis of 70 years. Although younger individuals (in their 30s-40s) can develop CLL, the incidence rises dramatically with age ...

Vascular resistance in the skin is very closely related to temperature of both outside and body core. Vascular resistance in other body organs is not related to outside temp and the body core temp (37C IS correct) does not change much in absence of disease. Studies mentioned above do not imply a cause, only a statistical relationship. Lots of things ...

The common consensus seems to be that in cold weather the heart must work harder to maintain the body temperature, and that the arteries contract to save energy, which leads to an increased rate of heart attacks. 'In discussing the weather-heart attack connection, study leader David Erlinge, a professor of cardiology, said cold and windy weather “leads to a ...

From this article: Scientists from the University of Tokyo are unsure whether it is the napping itself or an underlying condition which makes people more sleepy, that is driving the effect. After examining more than 200 studies involved 261,000 participants, they found that severe daytime fatigue was associated with a 56 per cent increased risk of ...

Occupational therapists primarily use functional activities to assess and treat individuals who have lost independence due to illness or injury. It is uncommon to use craft type activities outside of mental health and paediatrics unless it holds some specific meaning for the individual undergoing treatment. In assessing an individual who has undergone ...

There are many circumstances in which angioplasty would not be performed. First, let's look at when it is performed: Clinical indications for PCI [Percutaneous coronary intervention, or angioplasty] include the following: Acute ST-elevation myocardial infarction (STEMI) Non–ST-elevation acute coronary syndrome (NSTE-ACS) Unstable angina Stable angina ...
