Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

In western societies hypercholesterolemia is one of the major and independent factors that predispose to cardiovascular disease and death from them. According to the clinical study ATTICA, conducted during the years 2001-2002, in which randomized 1514 men and 1528 women, rates of hypercholesterolemia observed in a sample of urban population was 39% for men and 37% women . The prevalence in the corresponding U.S. epidemiological study NIANES was 52% for men and 49% women. The relationship between cholesterol, lipid-lowering therapy and risk of cardiovascular disease appears to be quite clear in the secondary prevention trials, the 4S (Scandinavian Simvastatin Survival Study), CARE (Cholesterol And Recurrent Events) and LIPID (Long-term Intervention with Pravastatin in Ischemic Disease) which showed the benefits of lowering LDL cholesterol in patients with coronary artery disease. Despite these remarkable results, studies were secondary prevention as a major shortcoming, the lack of patients with acute coronary events. This gap came to cover the study MIRACL (Myocardial Ischemia Reduction with Aggressive Cholesterol Lowering). In MIRACL study , atorvastatin 80 mg was evaluated in 3,086 patients (atorvastatin n = 1.538, placebo n = 1.548), acute coronary syndrome (myocardial infarction without Q-wave or unstable angina). Treatment was initiated during the acute phase after hospital admission and lasted for a period of 16 weeks. Treatment with atorvastatin 80 mg / day increased the latency of the combined primary endpoint, defined as death from any cause, nonfatal myocardial infarction, resuscitated cardiac arrest, or angina with objective evidence of myocardial ischemia requiring admission to hospital, indicating a risk reduction of 16% (p = 0,048). This was mainly due to a 26% reduction in re-hospitalization for angina with objective evidence of myocardial ischemia. The other secondary endpoints were not statistically significant by themselves (total: placebo: 22.2%, Atorvastatin: 22.4%).

Statins by reducing coronary syndromes, it appears that contribute to reducing the incidence of cardiovascular diseases. This is exactly what was observed in 4S, in which the incidence of chronic heart failure (CHF) during follow-up was 10.3% for those who received placebo and 8.3% in the simvastatin group, a finding which translates 19% reduction in heart failure (P \<0,015) nationwide with the appearance episode (event) CV.

Detailed Description

Determination of cardiovascular risk

If the assessment of cardiovascular risk remains incomplete, can identify indicators that measure risk:

1. Framingham Risk Score: Includes age, sex, total and HDL-CHOL, and levels of blood pressure (can underestimate the risk in some patients).
2. PROCAM Risk Score: also includes triglycerides, fasting glucose tolerance and family history.
3. Reynolds Risk Score: Includes family history and levels of hsCRP.
4. Greek Score (www.hearts.org / greece). People with low risk The Framingham Risk Score shows \<10% chance of cardiovascular disease over the next 10 years. Dealing mainly with healthy dietary intervention or drugs when the levels of LDL-CHOL\> 190 mg / dL or atherogenic index (T-CHOL/HDL-CHOL)\> 6.

Medication is necessary in individuals with familial hypercholesterolemia to reduce the LDL CHOL \<100 mg / dL. For this reason, a careful family history taking physical examination. The Reynolds Risk Score may reclassify their low-risk patients at higher risk individuals.

Persons moderate risk This group includes mostly middle-aged people. The Framingham Risk Score shows 10-19% chance of cardiovascular disease over the next 10 years. However, a positive family history and high hsCRP (if available) can modify the level of risk. These people need to change my lifestyle for 3 months, but may then be necessary pharmacological lipid-lowering therapy in people with at least two major risk factors and levels of LDL-CHOL\> 130 mg / dL. The administration of lipid-lowering therapy in people with levels of LDL-CHOL 100-129 mg / dL is recommended for people with multiple cardiometabolic risk factors (visceral obesity, prediabetes, hypertension, etc.). The increase of atheromatic index (\> 5) and the presence of high (\> 2 mg / L) levels of CRP (if available) are also indications for lipid lowering regardless of the levels of LDL-CHOL.

Major risk factors: age\> 45 years (men),\> 55 years (women), positive family history of premature cardiovascular disease \[in the presence of major vascular events in first degree relatives \<55 years (men), \<65 years (women)\], hypertension , HDL-CHOL \<40 mg / dL, smoking.

Individuals at high risk The Framingham Risk Score shows\> 20% chance of cardiovascular disease over the next 10 years. At-risk individuals include:

A. Individuals with documented atherosclerotic disease (coronary artery disease, stroke, a significant degree of carotid stenosis, peripheral arterial disease, intermittent claudication, or aneurysm of the abdominal aorta).

B. All type II diabetic patients and patients with type I diabetes individuals older than 40 years.

C. People with chronic kidney disease with glomerular filtration (GFR) \<60 mL/min/1, 73 m2.

In these individuals need intensive lifestyle modification and direct administration lipid lowering medication such as statins.

According to the above that one epidemiological study nature that has the purpose of observing and recording the progress of patients after their exit from a cardiology clinic or hospital unit because the acid after a cardiovascular event has clinical relevance. Compliance with medical instructions, achieving treatment goals for lipids by the addition of atorvastatin and personalized medicine practice are open field study. So this will be the subject of this study in order to highlight the clinical significance of atorvastatin in achieving the objectives of lipids (mainly LDL-CHOL) in blood plasma of "sensitive" of this group of patients in the Greek population, as possible representative (qualitatively and quantitatively)sample.

Dyslipidemia

The lipids of the human body is cholesterol (useful for the synthesis of cell membranes, hormones adrenal and gonads, and is a component of bile, the liver secretes) and triglycerides (serve as fuel and energy storage in adipose tissue ). The dyslipidemias are disorders (quantitative or qualitative) of the metabolism of lipoprotein particles (LDL, chylomicrons, HDL, VLDL) that transport lipids in the body.

Categories dyslipidemias - Primary dyslipidemias

The most significant primary lipid disorders are:

1. Chylomicronemia (congenital or acquired): ↑ TRG → risk of acute pancreatitis.
2. Familial Hypercholesterolemia a Homozygous (1/1.000.000 people): ↑ LDL CHOL b heterozygous (1/500 people): ↑ LDL CHOL.
3. Mixed hyperlipidaemia Familial mixed (1/300 people): ↑ LDL-CHOL, ↑ TRG, ↓ HDL-CHOL.
4. Familial hypertriglyceridemia (1/2.000 people): ↑ TRG.
5. Familial decrease in HDL CHOL: ↓ HDL CHOL. Typically in patients with primary dyslipidemia needed medication. - Secondary dyslipidemias

In patients with abnormal lipid parameters of must exclude secondary dyslipidemias, ie disorders of lipid metabolism caused by diseases or drugs:

1. Diabetes
2. Hypothyroidism
3. Obstructive liver disease
4. Chronic kidney disease nephrotic syndrome-
5. Obesity
6. Alcohol abuse
7. Medications that cause dyslipidemia a progestin b Anabolic Steroids c Corticosteroids D. Diuretics in large doses e b-blockers f Antiretroviral Drugs Interferon g h. Retinoids Estrogen i tamoxifen. In patients with secondary dyslipidemia required treatment of primary disease. Determination cohort for screening (Table 1)

Statins - Atorvastatin

The cornerstone of treatment of dyslipidemia are statins.

Before initiation of lipid lowering requires the identification of lipid parameters {total cholesterol, triglycerides, HDL cholesterol and calculated LDL cholesterol \[from the equation LDL-CHOL = total cholesterol - (triglycerides / 5 + HDL cholesterol)\]} after fasting 12 - 14 hours, while the determination of glucose levels of TSH (to exclude underlying hypothyroidism) and transaminases (AST / ALT) and CPK to control the undesirable effects. Repeat determination of these parameters in patients who achieved their goals of treatment 2 times a year or when changing the therapeutic regimen. Repeat laboratory tests (lipid control effectiveness and liver enzymes and CPK for security control) after 12 weeks: a reason to discontinue treatment if ALT\> 3 times the upper normal range or CPK\> 5 times the upper normal range or in patients with myalgias. It should be noted that not necessitate interruption of treatment with statins or deferral of treatment in individuals with small increases in transaminases or CPK, while in these patients should be seeking other underlying causes of elevated liver and muscle enzymes. The choice of drug and dosage depend on the percentage change in HDL-CHOL necessary to achieve the objectives. Statins are usually the evening before bedtime the night. The lipid-lowering therapy is therapy for life, and most importantly, the patient adherence to treatment. It should be noted that doubling the dose of a statin results in additional reduction of HDL-CHOL (LDL) cholesterol by 6%.

The main goal of treatment is to reduce HDL-CHOL

The non HDL-CHOL (= T-CHOL - HDL-CHOL), proposed as a secondary target of lipid lowering mainly in people with high triglycerides. The target for the non HDL-CHOL is 30 mg / dL higher than the target for the HDL-CHOL. The decrease in triglycerides (\<150 mg / dL) and increased HDL-CHOL (\> 40 mg / dL for men and\> 50 mg / dL for women) is considered desirable targets mainly lipid lowering in diabetic patients and in patients with cardiometabolic risk factors. Has also been suggested as a target of treatment to reduce the atheromatous index (T-CHOL/HDL-CHOL \<4).

Atorvastatin is indicated as an adjunct to diet to reduce elevated total cholesterol, LDL-cholesterol, apolipoprotein B and triglycerides in adults, adolescents and children aged 10 years and older with primary hypercholesterolaemia, including heterozygous familial hypercholesterolaemia combined (mixed) hyperlipidemia (type IIa and IIv by Fredrickson), when response to diet and other nonpharmacological measures is inadequate.

Atorvastatin is also indicated to reduce total cholesterol and LDL - cholesterol in adults with homozygous familial hypercholesterolemia as an adjunct to other lipid-lowering treatments (eg LDL apheresis) or if such treatments are unavailable.

Is also used to prevent cardiovascular events in adult patients who are thought to have a high risk for a first cardiovascular event, as an adjunct to correction of other risk factors.

Atorvastatin is a selective, competitive inhibitor of HMG-CoA reductase, the enzyme responsible for the conversion of 3-hydroxy-3-methyl-glutaryl-coenzyme A to mevalonate, a precursor of sterols, including cholesterol. The triglycerides and cholesterol in the liver are incorporated into very low density lipoproteins (VLDL) and released into the plasma for delivery to peripheral tissues. The low density lipoprotein (LDL) is formed from VLDL and is catabolized primarily through receptor high affinity to LDL (LDL receptor).

Atorvastatin lowers cholesterol levels and lipoprotein plasma inhibiting HMG-CoA reductase and then the biosynthesis of cholesterol in the liver and increase the number of LDL receptors on the surface of liver cells which uptake and catabolism of LDL. Atorvastatin reduces LDL production and the number of particles of LDL. H atorvastatin causes profound and sustained increase of LDL receptor activity, in combination with a beneficial change in the quality of the circulating particles of LDL. Atorvastatin effectively reduces LDL-C in patients with homozygous familial hypercholesterolemia, a group of patients who do not usually respond to lipid-lowering medicines.

Atorvastatin in a dose-response study, was shown to reduce the concentration of T-CHOL (30% - 46%), the LDL-CHOL (41% - 61%), apolipoprotein B (34% - 50%) and triglycerides (14% - 33%) while producing variable increases HDL-CHOL and apolipoprotein A1. These results are so consistent in patients with heterozygous familial hypercholesterolaemia, non-familial forms of hypercholesterolemia and mixed hyperlipidemia, including patients with noninsulin-dependent diabetes mellitus.

It has been found that the decrease of the values of total cholesterol, LDL-CHOL and apolipoprotein B reduces the risk of cardiovascular events and mortality thereof.
