  2. RACE II
    Lenient ( resting <110) vs. strict (resting < 80 ) HR control in pts with AFib - lenient rate control was as effective as strict and required fewer office visits; 2010
  3. RE-LY
    In pts with Afib, Both doses of Dabigatran are non-inferior to warfarin in preventing stroke and systemic embolism with lower major bleeding profile; slight increase in GI bleeding; 2009
    Aggrenox BID is more effective for secondary prevention of stroke in pts with ischemic stroke/TIAs; 1996, 2006
    Warfarin > ASA > placebo in reducing stroke events in AFib. For high risk patients with Afib, Warfarin INR 2-3 is more effective than low intensity warfarin (INR 1.2-1.5) dosing plus ASA 325 (1.9% vs. 7.9% stroke rates respectively). For low risk patients, ASA 325 has acceptable low risk of stroke < 3%. Sub-study of SPAF III established high risk factors of the CHADS2 risk score; 1991, 1994, 1996
    apixaban was superior to warfarin in preventing stroke or systemic embolism, caused less bleeding, and resulted in lower mortality.; 2011
    use of plavix in pts with ACS, DES placed, on PPI who have risk of GI bleeding related to NSAID use or positive for H. pylori - When used with plavix, PPI reduces rate of GI outcomes without change in cardiovascular events. Weak recommendation in pts without risk of GI bleed; Important to note that the study didnot have adequate power, didnot include patients with high risk bleeding; 2010
    Used universal definition of MI. In pts with moderate-severe unstable angina, NSTEMI, and STEMI, Prasugrel (loading 60 then 10 daily) reduced CV death, nonfatal MI, nonfatal stroke compared to clopidogrel (loading 300 then 75 daily) at 1, 6, and 15 months; additionally, there's reduced stent thrombosis in prasugrel group. Similar bleeding profiles; 2007 - 19% reduction in CV death, MI or stroke compared with clopidogrel in patients undergoing PCI for ACS.
  9. PLATO
    Pts with ACS, with or without ST elevation, ticagrelor reduces death from vascular, MI, and CVAs; slight increase non-procedural related, i.e. fatal intracranial bleeding, but fewer other types of fatal bleeding; 2009
  10. GUSTO-I

    Plavix plus ASA reduces 30 day mortality (0.6% ARR), BB good after MI if pts do not have heart failure/cardiogenic shock; 2005
    Bivalirudin reduced bleeding and death compared to Heparin plus Glycoprotein IIb/IIIa inhibitor in 30 days; increased <24 hr in stent thrombosis with bivalirudin but offsetted between 24 hrs to 30 days; 2009
  16. TACTICS - TIMI 18
    GpIIb/IIIa inhibitor plus invasive strategy in pts with moderate-high risk UA/NSTEMI is better than conservative management; 2001

    plavix in addition to aspirin in patients with non-STEMI ACS reduces risk of CV death, MI, and CVAs by 20%; 2002
  18. CLARITY - TIMI 28
    In STEMI patients, plavix in addition to aspirin plus thrombolysis reduced CV death, occlusion of infarct-related artery, re-MI and by 20% at 30 days; 2005
  19. ISIS-4
    In pts with suspected or acute MI, Captopril reduced all cause mortality at 5 wks and long term follow up; increased rate of hypotension and/or renal dysfunction in pts with captopril warranting termination; no benefit conferred by magnesium sulfate or isordil; 1995
  20. GISSI 3
    Lisinopril, when given < 24 hrs in pts with acute MI, reduced mortality and severe LV diastolic dysfunction (EF < 35%); 1994

  26. SAVE (captopril, 1992), TRACE (trandolapril, 1995), SOLVD (enalapril, 1991)
    ACEI reduces all cause mortality (~ 20%), remodeling, and decreased risk of worsening heart failure (37%) when started 2-10 days after MI, and in pts with CHF (EF < 35%)
  27. VALIENT (valsartan, 22)
    ARBs have mortality equivalent to ACEI; side note: Angiotensin type 1 receptor blockers ( ARBs) have increased stimulation of angiotensin type 2 receptors, which have protective effect of decreased remodeling
    enalapril plus candesartan combination was more beneficial in preventing LV dysfunction (reduced ESV and EDV), compared to either drug alone ; 1999

    Irbesartan did not improve mortality or CV outcomes in pts with HF symptoms (Class II-IV) and preserved EF > 45%; Most pts (63%) had HF due to hypertensive heart disease; 2008
    Pts with severe HF (EF < 25%) and Class III-IV, Coreg in addition to diuretic plus ACE/ARB reduces all cause mortality and hospitalization; 2001

TAVI was just as good as surgery in surgery-eligible patients for the primary end point of mortality. More stroke/TIA, vascular complications seen in TAVI group but more major bleeds in surgery group. Better symtomatic improvement in TAVI. 2011
    Early invasive strategy in pts with STEMI has significant reductions in primary outcomes (death, stroke, reinfarction) at 30 days, but at 12 months, reductions were nonsignificant, but trended towards significance as invasive group had less incidence of death, strokes, reinfarction at 12 months; 2010

  68. VALUE
    Valsartan vs. Amlodipine in HTN control: Amlodipine has better HTN control in first few months, but equal efficacy at 6 years; Valsartan group had greater incidence of MI and Amlodipine group had greater incidence of new onset diabetes; 2004
  69. UKPDS (HTN in Diabetes study)
    BP control < 150/85 in pts with HTN and Diabetes with ACEI or BB, plus additional meds if needed, reduces risk of diabetic related complications and death related to diabetes (MI, PV0D, renal disease, CVA, sudden death) along with decrease in progression of neuropathy and retinopathy; 1998

  73. ALLHAT
    thiazide vs. CCB vs. ACEI - No significant difference in all cause mortality, fatal or nonfatal coronary heart disease (CHF). Thiazide type diuretics (chlorthalidone) are superior at preventing 1 or more forms of CVD and should be first line of therapy; amlodipine higher 6 yr rate of HF and lisinopril had higher 6 yr rates of CHD, stroke, and HF; 2002
