Coronary Angiography

Publication Title: 
Herz

A chronic coronary occlusion consists of an atherosclerotic plaque and one or several thrombi. It clinically imitates a tight stenosis but is exempt from the risk of truly unstable angina or myocardial infarction. Hence, quality of life is at stake and not longevity. This holds true for balloon angioplasty as well as for surgery. Indications for angioplasty are based on an estimate of technical difficulties and clinical risks balanced against potential subjective benefit and amount of viable myocardium concerned.

Lipoproteins and the impact of lipid lowering on progression and regression of coronary artery disease are discussed. Angiographically assessed regression studies are reviewed (NHLBI, LIT, LHT, CLAS I and II, FATS, POSCH, Heidelberg, STARS, SCRIP, MAAS, PLAC I, HARP, UC-SF), as are B-mode ultrasound studies (ACAPS, PLAC II) and survival studies (Oslo diet-smoking study, SSSS, Pravastatin, Oxford). Although study populations and the interventions are different in the studies, I have come to the following conclusions.

Previously we discovered that routine periodic fasting was associated with a lower prevalence of coronary artery disease (CAD). Other studies have shown that fasting increases longevity in animals. A hypothesis-generating analysis suggested that fasting may also associate with diabetes. This study prospectively tested whether routine periodic fasting is associated with diabetes mellitus (DM). Patients (n = 200) undergoing coronary angiography were surveyed for routine fasting behavior before their procedure.

OBJECTIVE: To evaluate whether telomerase activity, measured in circulating blood leukocytes, might be associated with prevalent atherosclerosis, or predict future coronary artery disease risk. METHODS AND RESULTS: We examined associations of telomerase activity levels measured at year 15 in the Coronary Artery Risk Development in Young Adults (CARDIA) Study with prevalent coronary artery calcium (CAC), progressive CAC at year 20, and incident CAC between years 15 and 20, in 440 black and white men aged 33-45 years. Telomere length was also measured in a subset of participants (N=129).

The reuse of percutaneous transluminal coronary angioplasty (PTCA) balloon catheters has recently been proposed as a way of containing costs. Our aim was to examine patient acceptability of this strategy. We asked 100 consecutive patients scheduled for potential or definite PTCA whether they would permit the use of sterilized, reused balloon catheters. We collected demographic, clinical, angiographic, and insurance-status data on all patients. Sixty-eight patients responded that they would have allowed reused equipment (group 1). Thirty-two patients would have refused (group 2).

OBJECTIVES: Yoga based lifestyle modifications have been earlier shown to be beneficial in coronary artery disease in a small number of patients. We evaluated the role of lifestyle modification based on Yoga techniques, stress management and dietary modifications in retardation of coronary artery disease. METHODS: This prospective, controlled, open trial included angiographically proven coronary artery disease patients (71 patients in study group and 42 patients in control group).

BACKGROUND: Yoga has potential for benefit for patients with coronary artery disease though objective, angiographic studies are lacking. MATERIAL AND METHODS: We evaluated possible role of lifestyle modification incorporating yoga, on retardation of coronary atherosclerotic disease. In this prospective, randomized, controlled trial, 42 men with angiographically proven coronary artery disease (CAD) were randomized to control (n = 21) and yoga intervention group (n = 21) and were followed for one year.

AIMS: To evaluate the efficacy of a unique healthy and happy lifestyle (HLS) program in regression of coronary atherosclerosis and reduction in cardiac events in an open trial. METHODS: One hundred and twenty three angiographically documented moderate to severe coronary artery disease (CAD) patients were administered HLS comprising of low-fat, high-fiber vegetarian diet, moderate aerobic exercise and stress-management through Rajyoga meditation.

Cardiogenic shock is a very serious complication of acute myocardial infarction because of its prevalence (10-15% of cases) and the associated mortality of 80 to 90 per cent despite the availability of new inotropic drugs and intra-aortic balloon counterpulsation. The aim of this study was to show that revascularisation by percutaneous transluminal coronary angioplasty (PTCA) in acute myocardial infarction complicated by cardiogenic shock completely changes the prognosis.
