Big study casts doubt on need for many heart procedures

A large study finds that people with stable heart disease from clogged arteries may have less chest pain if they get a stent or bypass procedure, but it won't cut their risk of having a heart attack or dying over the next few years

This study suggests that for most, managing CAD with medications alone (the conservative approach) is as safe and effective as the more invasive strategy of cardiac catheterization and opening of the blocked artery. Findings of the ISCHEMIA trial ISCHEMIA followed over 5,000 patients with significant narrowing in one or more coronary arteries. Half of the patients were randomly selected to receive conservative treatment with optimal medical therapy (OMT) and lifestyle changes to treat risk factors such as high blood pressure and high cholesterol. The other half were given OMT and also sent for cardiac catheterization (thre...

The headline in a main Finnish newspaper on 16 November announced: “Trust and interest for published science has increased in Finland”. I would have hypothesized that evidence-based knowledge was losing the game against the rush of non-scientific and commercial information – but I was wrong. A 3-year follow-up survey among the Finland population was clear on this. Could the growth in electronic and social media information actually be causing people to search for knowledge based on scientific facts? Forty-five years have passed since the publication of the first issue of the Scandinavian Journal of Work...

New research could slash the number of people getting stents or bypass surgery for coronary artery disease. A study looks at a more than 5,000 people with blocked arteries, but without severe symptoms like extreme pain or heart attack. It found that regularly taking medications along with lifestyle changes was just as effective at preventing heart attacks as the more invasive procedures. Cardiologist Dr. Tara Narula joins "CBS This Morning" to discuss the findings.

This study clearly goes against what has been the common wisdom for the last 30, 40 years” and may lead to less testing and invasive treatment for such patients in the future, said Dr. Glenn Levine, a Baylor College of Medicine cardiologist with no role in the research. Some doctors still may quibble with the study, but it was very well done “and I think the results are extremely believable,” he said. About 17 million Americans have clogged arteries that crimp the heart’s blood supply, which can cause periodic chest pain. Cheap and generic aspirin, cholesterol-lowering drugs and blood pressure medic...

Acute coronary syndrome (ACS) leads to clinical symptoms such as chest pain, dyspnea, and arrhythmia. The occurrence of ACS is mainly related to the vulnerable plaques in the coronary arteries. MicroRNA-21 (miR-21) is widely expressed in cardiovascular disease and considered as a marker of myocardial infarction, but its role in vulnerable atherosclerotic plaque of ACS is poorly studied. The cases of ACS and control group were selected in 2 years. Our results revealed that miR-21 was highly positively correlated with the maximum lipid core area, the number of diseased vessels, the number of macrophages, the number of vulner...

Rationale: Coronary angiography (CAG) findings of acute myocardial infarction (AMI) in pregnant women are characterized by a high incidence of normal coronary arteries. This is the first report of AMI with normal coronary arteries during pregnancy, showing coronary spasm and pregnancy-related acquired protein S (PS) deficiency. Patient concerns: A 30-year-old Japanese woman was admitted to an emergency department. One hour before admission, she developed sudden onset of precordial discomfort, back pain, and dyspnea. She was a primigravida at 39 weeks’ gestation and had no abnormality in the pregnancy thus far. S...

A 50-something woman with history of CHF of unknown etiology, and of HTN, presented for evaluation of chest pressure.Her BP was 223/125, Sp02 98% on RA. HR 106, RR 18. Here was her ED ECG:There is sinus rhythm with Left Bundle Branch Block (LBBB)There is a large amount of ST Elevation in V2 and V3 (more than 5 mm)Thus, this meets the unweighted Sgarbossa Criteria of 5 mm of discordant ST ElevationBut it does NOT meet the Smith Modified Sgarbossa Criteria, which depend on the ST/S ratio.This ratio is critical because LBBB with very large depolarization voltage (QRS) also has very large repolarization voltage (ST/T).Her...

We examined 9293 individuals from the Copenhagen General Population Study using nuclear magnetic resonance spectroscopy measurements of total cholesterol, free- and esterified cholesterol, triglycerides, phospholipids, and particle concentration. Fourteen subclasses of decreasing size and their lipid constituents were analysed: six subclasses were very low-density lipoprotein (VLDL), one intermediate-density lipoprotein (IDL), three low-density lipoprotein (LDL), and four subclasses were high-density lipoprotein (HDL). Remnant lipoproteins were VLDL and IDL combined. Mean nonfasting cholesterol concentration was 72...

(Natural News) Heart disease is caused by problems related to the arteries. The narrowing or blockage of these blood vessels, which deliver blood to and from the heart, can cause significant damage and result in heart attack, chest pain, or stroke. Because the cholesterol that builds up along the walls of the arteries comes mostly from...
