Or to an entire substance class. Moreover, it would be equally unacceptable to conclude from improvement of surrogate parameters on clinical events and on cost-effectiveness. Under these circumstances, treatment should proceed strictly from the results of the published studies. Despite all the evidence that lipid lowering with statins under clearly defined conditions is cost-effective, this therapy, similar to revascularisation procedures in patients with CAD, would involve large expenses, which would remarkably strain the health-care budget. According to estimates from the USA, the treatment of a non-fatal myocardial infarction for one year amounts to 14, 682 converted from US$ ; [14]. The prevention of a myocardial infarction by lipid lowering with statins would cost, according to the proposed calculation model, 45, 550, ie, approximately three times as much. Nevertheless, the prevention of one myocardial infarction is most probably more cost-effective than the expenditure for all the health-related and social consequences that result from one infarction, especially within the first year. The recently published AVERT-study addresses the issue of the cost-effectiveness of the drug-induced lipid reduction as opposed to revascularisation procedures in order to prevent ischaemic events as an endpoint of CAD [15]. Again the question arises, whether the prevention of an ischaemic event would be more cost-effective than its treatment. The former is more likely viable in the case of a stable CAD than in acute myocardial infarction. According to the AVERT report, treating a patient with atorvastatin 80 mg day ; for 18 months would cost 4, 605. A PTCA, depending on the number of stents used, in Austria costs approximately 3, 000 to 5, 000. The fact remains that the therapeutic long-term effect of either treatment modality cannot be predicted with certainty for each individual case. Due to the present situation, in terms of classifying the patients concerned as high-risk, it is therefore necessary to combine both treatment strategies. A major limitation with regard to the practical application of the results from AVERT lies in the fact that two treatment methods were compared that do not necessarily share the same goal. The main focus of the PTCA still remains the more symptomatic treatment of a stable angina pectoris, whereas the aim of lowering lipids eg with statins is a reduction in the number of future coronary events ie, the PTCA influences the symptoms and the lipid treatment preferentially affects the prognosis of CAD. Also this perspective allows a synergistic effect of both treatment strategies. Measures that promote a healthy lifestyle for the general population, especially for the high-risk groups, are economical and an integral part of the comprehensive treatment of CAD [16]. However, it remains undisputed that a change in.
Sive treatment regimen in retarding the progression of coronary artery disease.84 Similar enhanced benefits on retarding the anatomic progression of coronary atherosclerosis were shown for a more aggressive lipidlowering treatment strategy in the Reversal of Atherosclerosis with Aggressive Lipid Lowering REVERSAL ; study85 and large randomized trials such as Myocardial Ischemia Reduction with Acute Cholesterol Lowering MIRACL ; , Pravastatin or Atorvastatkn Evaluation and Infection Therapy PROVE-IT ; , Aggrastat to Zocor A to Z ; , and Treating to New Targets TNT ; indicate that early and more aggressive lipid-lowering statin therapy provides more benefit than delayed and less aggressive statin regimens, both in patients with recent acute MI and in those with chronic stable CHD.86-89 Based on results of these trials some guidelines have been recently updated and suggest that more aggressive LDL cholesterol lowering to levels 1.8 mmol L ; should be achieved in secondary prevention.90. Atorvastatin drug reactionsPosted at: suntory successfully isolates diabetic complication preventive component in whisky through joint industry-academia research on june 3, suntory announced the latest achievement in its research on whisky and captopril. Argument of benefit versus risk associated with more aggressive therapy." Noting that data from the PROVE-IT TIMI 22 trial confirm that event rates are lower in patients who achieve LDL-C levels under 40 mg dL, 43 Dr. Davidson said, "I think we could still argue that lower is better." Certain groups are at higher risk of suffering a cardiovascular event while on statin therapy, pointed out Dr. Davidson. In landmark secondary-prevention statin trials, he noted, patients with diabetes and patients with low HDL-C have a higher residual risk. "We recognize that the patient with diabetes and low HDL-C represents high residual risk, even on statin therapy, " remarked Dr. Davidson. In a recent analysis of more than 30, 000 managed-care patients, 44 Charland and associates assessed the cardiovascular risk of those patients achieving optimal goals for LDL-C, HDL-C, and TG [Figure 11]. "Those patients who achieved none of the three goals had a 40% higher risk of sustaining a cardiovascular event, " noted Dr. Davidson. "Those patients achieving all three of the goals had the lowest relative risk." He suggested that future assessments of total risk benefit management of lipid profiles should take into consideration that optimal lipid management further reduces risk in the high-residual-risk statin patient. Dr. Davidson turned his attention toward a new challenge in lipid management. "We know that lower is better, but how do we aggressively lower LDL-C without increasing the risk of adverse events? An analysis of data from landmark trials shows a very slight increase in liver enzyme elevations with more-aggressive lowering of LDL-C. I, personally, have been very impressed by the safety of high-dose atorvastatin in both the TNT3 and the IDEAL4 trials, but there still is a slight increase in liver enzymes that needs to be recognized in these trials." As for muscle symptoms, he continued, there are "very low rates in general, but with simvastatin 80 mg a slight increase in rates of myopathy. 20 using diet and drugs instead of catheters and surgeries? Unfortunately, the answer is usually no. Some patients with blocked coronary arteries causing cardiac chest pain called "angina" ; can improve with diet and drugs, but usually they do not improve very much. The very best diet and drug regimens might improve coronary artery blockage by, on average, 1% to 2% we'll discuss this later ; . This is not a very meaningful percentage improvement when the blockages causing anginal chest pain are 70% to 99% blockages. As research studies were performed to measure the effect of diet and cholesterol drugs on coronary artery blockages, a startling and important discovery was made. Although, as stated above, the degree of blockage changed very little, the number of heart attacks and heart-related deaths in the patients dropped dramatically. In a few studies, the number of heart attacks, heartrelated deaths, and episodes of rapidly worsening chest pain dropped by 70% to 80%. In many studies, these "cardiac events" dropped by 20% to 40%. These results were far out of proportion to the tiny 1% to 2% improvements in the heart blockages. What was going on? The answer seems to be as follows: Diet and cholesterol drugs do not change the overall size of atherosclerotic plaques very much at all, so that the blockages improve very little. However, diet and cholesterol drugs have some kind of effect on plaques to make them much less prone to rupture. As stated at the beginning of this section, the "vulnerable plaques are stabilized." Experiments in animals have helped us to understand what happens when vulnerable, ruptureprone plaques are stabilized. You may recall that macrophages in the fibrous cap of atherosclerotic plaques play an important role in plaque rupture. Macrophages make enzymes that break down the fibrous proteins of the arterial wall. These macrophages also form many large foam cells that can almost totally occupy parts of the fibrous cap. In animal experiments, when LDL levels in the blood are lowered and or when HDL levels are raised, the foam cells lose their cholesterol, and eventually the foam cells and most of the macrophages disappear from the atherosclerotic plaque. What is left behind is strong fibrous tissue that is not prone to rupture. This improvement in the atherosclerotic plaque can be accomplished within one to three months in animal experiments. It is thought that the same things happen in human atherosclerotic plaques, when LDL is lowered, HDL is raised, or both. It is possible to stabilize the vulnerable plaque, even when the overall size of the plaque changes very little. Certainly this is good news, since almost all heart attacks, most strokes, and most cardiovascular deaths appear to happen when vulnerable plaques rupture. The take-home message is this: When a person is experiencing severe anginal chest pain due to coronary artery blockages, that person usually needs a heart catheterization. A balloon procedure to stretch open a blocked artery may then be performed, often with placement of one or more stents, or alternatively, coronary bypass surgery may be performed. These procedures in the catheterization laboratory or in the operating room do a good job of relieving anginal chest pain. However, these procedures usually don't reduce the risk of subsequent heart attacks, strokes, and heart-related or vascular deaths very much. That is a job for diet, lifestyle, and drug treatment, which can drop the risk of sudden atherosclerotic events by half or more. Treatment of atherosclerosis with diet, lifestyle, and drugs changes the risk factors such as LDL, HDL, blood pressure, and smoking. In addition, drugs that partially block blood clotting, such as aspirin, can help to prevent heart attacks, strokes, and cardiovascular deaths. So, getting your arteries opened up with balloons and stents, or getting your arteries bypassed surgically does not and diltiazem. 2.
