Title: Action to Control Cardiovascular Risk in Diabetes (ACCORD)
Brief Summary: The purpose of this study is to prevent major cardiovascular events (heart attack, stroke, or cardiovascular death) in adults with type 2 diabetes mellitus using intensive glycemic control, intensive blood pressure control, and multiple lipid management.


Options:
A: Inclusion Criteria:

* Diagnosed with type 2 diabetes mellitus, as determined by the new American Diabetes Association guidelines, which include a fasting plasma glucose level greater than 126 mg/dl (7.0 mmol/l), or a 2-hour postload value in the oral glucose tolerance test of greater than 200 mg/dl, with confirmation by a retest
* For participants aged 40 years or older, history of CVD (heart attack, stroke, history of coronary revascularization, history of peripheral or carotid revascularization, or demonstrated angina)
* For participants aged 55 years or older, a history of CVD is not required, but participant must be considered to be at high risk for experiencing a CVD event due to existing CVD, subclinical disease, or 2+ CVD risk factors
* HbA1c 7.5%-9% (if on more drugs) or 7.5%-11% (if on fewer drugs)
B: Inclusion Criteria:

* Male or female
* Age 50 to no upper limit
* Hypertension documented according to the 6th report of the Joint National Committee on Detection and Evaluation of the treatment of high BP (JNC VI) and the need for drug therapy (previously documented hypertension in patients currently taking antihypertensive agents is acceptable)
* Documented CAD (e.g., classic angina pectoris (stable angina pectoris; Heberden angina pectoris), myocardial infarction three or more months ago, abnormal coronary angiography, or concordant abnormalities on two different types of stress tests)
* Willingness to sign informed consent

Exclusion Criteria:

* Unstable angina, angioplasty, coronary artery bypass graft surgery (CABG) or stroke within one month. Patients taking beta blockers after myocardial infarction are excluded if study enrollment is planned within 12 months of myocardial infarction. No time limitation if not taking beta-blocker.
* Use of a ß-blocker within past two weeks
* Patients without a pacemaker and any of the following:

  * Sinus bradycardia (\< 50 beats/min.)
  * Sick sinus syndrome
  * Atrioventricular (AV)-block of more than 1st degree
* Documented contraindication to verapamil; documented contraindication to both atenolol and hydrochlorothiazide
* Atrial fibrillation/flutter with Wolff-Parkinson-White (WPW)-Syndrome
* Severe heart failure (New York Heart Association \[NYHA\] IV).
* Concomitant illnesses (e.g., severe renal failure \[Serum creatinine ≥4.0 mg/dl\], severe hepatic failure or known cirrhosis, etc.) which may affect outcome variables or where life expectancy is two years or less or which are likely to require frequent hospitalizations and/or treatment adjustments.
* Patients with psychiatric, cognitive, or social (e.g., alcoholism, etc.) conditions that would interfere with giving consent or cooperating or remaining available for follow-up for two years.
C: 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
D: Inclusion Criteria:

* written informed consent to the study
* age \>= 55 years at randomization. There is no upper age limit
* systolic blood pressure \>= 150 mmHg in 2 visits at distance of 7-14 days, irrespective of diastolic pressure. Duration of treatment before visit 1 must be at least 12 weeks
* at least one additional risk factor including the following:
* current cigarette smoking
* total cholesterol \>= 20 mmg/dl, or High Density Lipoproteins (HDL) \< 40 mg/dl, or Low Density Lipoproteins (LDL) cholesterol \>= 130 mg/dl
* family history of cardiovascular disease in male first degree relative \< 55 years or female first degree relative \< 65 years
* previous TIA or stroke
* previous coronary artery disease
* history of peripheral occlusive arterial disease (claudication intermittens associated with angiographic or echographic evidence of \> 60% stenosis)

Exclusion Criteria:

* diabetes (fasting glucose \> 125 mg/dl in two samples or ongoing diabetic treatment)
* renal failure, defined by a serum creatinine \> 2.0 mg/dl
* chronic atrial fibrillation or flutter
* clinically significant hepatic or hematological disorders, alcoholism, drug addiction
* causes precluding ECG interpretation for LVH: complete right or left bundle block, Wolff-Parkinson-White syndrome, previous Q-wave myocardial infarction
* any disease causing reduced life expectancy
* unwilling to participate
* significant (more than traces of) valvular heart disease
