Effect of Statins on Lipid Levels Following the First Acute Coronary Event (MK-0000-204)

Study Overview
=================
Brief Summary
-----------------
The current study is proposed to investigate the pattern of dyslipidemia and of lipid treatment practices in patients in India experiencing their first acute cardiovascular event and the extent of residual dyslipidemia after 12 weeks of treatment with statins. Dyslipidemia definitions are per the National Cholesterol Education Program - Adult Treatment Panel III (NCEP-ATP III).

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Total Cholesterol (TC) Levels at First Acute Coronary Event | At the time of hospital admission for a first acute coronary event, the TC levels of eligible participants were taken. This level was considered the baseline value. A TC level of >240 mg/dL is considered an abnormal lipid value (dyslipidemia). | At hospital presentation (Day 1) | 
| Low-Density Lipoprotein Cholesterol (LDL-C) Levels at First Acute Coronary Event | At the time of hospital admission for a first acute coronary event, the LDL-C levels of eligible participants were taken. This level was considered the baseline value. A LDL-C level of >70 mg/dL is considered an abnormal lipid value (dyslipidemia). | At hospital presentation (Day 1) | 
| High-Density Lipoprotein Cholesterol (HDL-C) Levels at First Acute Coronary Event | At the time of hospital admission for a first acute coronary event, the HDL-C levels of eligible participants were taken. This level was considered the baseline value. A HDL-C level of <40 mg/dL is considered an abnormal lipid value (dyslipidemia). | At hospital presentation (Day 1) | 
| Triglycerides (TG) Levels at First Acute Coronary Event | At the time of hospital admission for a first acute coronary event, the TG levels of eligible participants were taken. This level was considered the baseline value. A TG level of >150 mg/dL is considered an abnormal lipid value (dyslipidemia). | At hospital presentation (Day 1) | 
| Change From Baseline in TC Levels After Treatment | TC levels were measured after 12 weeks of treatment with a statin. The change from baseline was calculated as the difference between baseline and Week 12 values. | Baseline and at Week 12 | 
| Change From Baseline in LDL-C Levels After 12 Weeks of Treatment With Statins | LDL-C levels were measured after 12 weeks of treatment with a statin. The change from baseline was calculated as the difference between baseline and Week 12 values. | Baseline and at Week 12 | 
| Change From Baseline in HDL-C Levels After 12 Weeks of Treatment With Statins | HDL-C levels were measured after 12 weeks of treatment with a statin. The change from baseline was calculated as the difference between baseline and Week 12 values. | Baseline and at Week 12 | 
| Change From Baseline in TG Levels After 12 Weeks of Treatment With Statins | TG levels were measured after 12 weeks of treatment with a statin. The change from baseline was calculated as the difference between Baseline and Week 12 values. | Baseline and at Week 12 | 
| Percentage of Participants Who Achieved Target Lipid Levels for LDL-C But Did Not Achieve Target Lipid Levels for HDL-C and TG After 12 Weeks of Treatment With Statins | The percentage of participants who achieved predefined lipid target levels after 12 weeks of treatment with statins. Predefined lipid target levels were: LDL-C less than 70 mg/dL, HDL-C greater than 40 mg/dL, and TG less than 150 mg/dL. | Week 12 | 
| Percentage of Participants Who Achieved Target Lipid Levels for TG and LDL-C But Did Not Achieve Target Lipid Levels for HDL-C After 12 Weeks of Treatment With Statins | The percentage of participants who achieved predefined lipid target levels after 12 weeks of treatment with statins. Predefined lipid target levels were: LDL-C less than 70 mg/dL, HDL-C greater than 40 mg/dL, and TG less than 150 mg/dL. | Week 12 | 
| Percentage of Participants Who Achieved Target Lipid Levels of HDL-C and LDL-C But Did Not Achieve Target Lipid Levels for TG After 12 Weeks of Treatment With Statins | The percentage of participants who achieved predefined lipid target levels after 12 weeks of treatment with statins. Predefined lipid target levels were: LDL-C less than 70 mg/dL, HDL-C greater than 40 mg/dL, and TG less than 150 mg/dL. | Week 12 | 
| Percentage of Participants Who Did Not Achieve Target Lipid Levels for LDL-C, HDL-C, and TG After 12 Weeks of Treatment With Statins | The percentage of participants who achieved predefined lipid target levels after 12 weeks of treatment with statins. Predefined lipid target levels were: LDL-C less than 70 mg/dL, HDL-C greater than 40 mg/dL, and TG less than 150 mg/dL. | Week 12 | 
| Percentage of Participants Who Achieved Target Lipid Levels for TG But Did Not Achieve Target Lipid Levels for HDL-C and LDL-C After 12 Weeks of Treatment With Statins | The percentage of participants who achieved predefined lipid target levels after 12 weeks of treatment with statins. Predefined lipid target levels were: LDL-C less than 70 mg/dL, HDL-C greater than 40 mg/dL, and TG less than 150 mg/dL. | Week 12 | 
| Percentage of Participants Who Achieved Target Lipid Levels of HDL-C But Did Not Achieve Target Lipid Levels for TG and LDL-C After 12 Weeks of Treatment With Statins | The percentage of participants who achieved predefined lipid target levels after 12 weeks of treatment with statins. Predefined lipid target levels were: LDL-C less than 70 mg/dL, HDL-C greater than 40 mg/dL, and TG less than 150 mg/dL. | Week 12 |
