Optimal Blood Pressure and Cholesterol Targets for Preventing Recurrent Stroke in Hypertensives "ESH-CHL-SHOT"


Phase 4 Results N/A

Eligibility Criteria

Inclusion Criteria

- Qualifying event: stroke or TIA 1 to 6 months previous to randomization.
- All patients should have a CT scan or MRI (preferably MRI) at screening. The CT scan or MRI carried out at the time of the qualifying event, if available, is acceptable. Stroke will be defined as imaging evidence of a recent brain infarction (or haemorrhage) independently of duration of clinical symptoms, or as duration of clinical symptoms > 24 h even in absence of imaging evidence of lesion
- TIA as clinical symptoms (involving limbs or speech) lasting < 24 h without imaging evidence of infarction. Enrolling units should avoid enrolling patients with TIA in a proportion greater than 25% of enrolled patients. The general coordinators in Milan and Beijing may decide stopping enrolment of TIA patients if their proportion is becoming greater than expected.
- A haemorrhagic stroke (1 to 6 months previously) is also a qualifying event, but only for the BP-lowering component of the trial (see Exclusion criteria).
- Age: 65 years and above. No fixed upper age limit is introduced, but frail patients aged above 80 years should not be enrolled.
- Gender: either gender.
- BP: Only hypertensive patients: untreated patients with SBP ≥140 mmHg; patients on antihypertensive treatment with any BP (but see exclusion criteria)
- LDL-C: Patients without statin treatment with LDL-C > 2.8 mmol/l; patients on statin treatment with any LDL-C value (but see exclusion criteria)
- Antiplatelet therapy: All patients should be under antiplatelet therapy (agents and doses chosen by the investigator according to accepted guidelines), unless contraindicated. Anticoagulant (instead of antiplatelet) therapy whenever indicated (e.g. atrial fibrillation).

Exclusion Criteria

- Qualifying event:
1. Patients in unstable clinical conditions
2. Clinical disturbances caused by non-stroke pathology
3. patients with haemodynamically significant carotid stenosis or requiring carotid revascularization
4. haemorrhagic stroke is an exclusion criterion for the lipid lowering component of the trial; however, these patients should be randomized to the BP component, but considered in addition to the number of patients requested to each enrolling unit, in order not to decrease the power of the lipid-lowering component.
- BP: - known secondary hypertension;
- SBP >140 mmHg under three antihypertensive drugs at full doses (these patients are unlikely to achieve SBP < 125 mmHg, if so randomized);
- orthostatic hypotension (SBP fall > 25 mmHg on standing);
- LDL-C: - LDL-C >2.8 mmol/l under full dose of a statin (these patients are unlikely to achieve LDL-C targets).
- LDL-C > 4.5 mmol/l under low dose of a statin or untreated (these patients are unlikely to achieve the lower LDL-C target).
- Others: - Patients with a myocardial infarction (preceding or subsequent to the qualifying stroke or TIA) if their baseline LDL-C is < 1.8 mmol/l
- Dementia
- Severe disability (modified Rankin scale > 4)
- Severe chronic renal failure defined as serum creatinine > 250 micromol/l
- Hepatic disease as determined by either AST or ALT values > 2 times the upper limit of normal
- History of hepatic encephalopathy, esophageal varices or portocaval shunt
- History of gastrointestinal surgery or disorders which could interfere with drug absorption
- Known allergy or contraindications to one of the drugs to be administered in the study
- History of malignancy including leukaemia and lymphoma (but not basal cell skin cancer) within the last 5 years
- History of clinically significant autoimmune disorders such as systemic lupus erythematosus
- History of drug or alcohol abuse within the last 5 years
- History of non-compliance to medical regimens and/or patients who are considered potentially unreliable
- Inability or unwillingness to give free informed consent
