PCSK9 inhibitors
-2341 patients at high risk for cardiovascular events who had LDL >70
-receiving treatment with statins at the maximum tolerated dose
- alirocumab (150 mg) or placebo as a 1-ml subcutaneous injection every 2 weeks
for 78 weeks
-primary efficacy end point was the percentage change in calculated
LDL cholesterol level from baseline to week 24
-enrolled 4465 patients
-randomly assigned in a 2:1 ratio to receive either evolocumab
(140 mg every 2 weeks or 420 mg monthly) plus standard therapy or standard therapy alone
-Patients were followed for a median of 11.1 months
-Data from the two trials were combined
75 mg SC q2 weekly
Max dose 150 mg q2 weekly
140 mg SC every two weeks or
420 mg SC monthly
Approved as an adjunct to
statins • Maximally tolerated statin therapy for treatment of adults
with heterozygous familial hypercholesterolemia (HeFH)
or clinical atherosclerotic cardiovascular disease (CVD),
who require additional lowering of LDL
• Other LDL-lowering therapies (e.g., statins, ezetimibe,
LDL apheresis) in patients with homozygous familial
hypercholesterolemia (HoFH) who require additional
lowering of LDL-C
• The effect on cardiovascular morbidity
and mortality has not been determined
Heart Failure
• TOPCAT
• SHIFT trial
• PARADIGM HF trial
• randomized, double-blind trial
• 3445 patients with symptomatic heart failure and EF>45%
• spironolactone (15 to 45 mg daily) or placebo
• primary outcome was a composite of CV death, aborted cardiac arrest,
or hospitalization for the management of heart failure
• mean follow-up of 3.3 years
Death, HF hospitalization HF hospitalization
• Double blind RCT
• 8442 patients with class II, III, or IV heart failure and an ejection fraction of <40%
• LCZ696 (at a dose of 200 mg twice daily) or enalapril (at a dose of 10 mg twice daily)
• primary outcome was a composite of death from CV causes or hospitalization for HF
Atrial Fibrillation
• Post stroke monitoring
• Novel anticoagulant
Warfarin
Highlights
• A strategy of anatomical testing with the use of CTA, as
compared with use of functional testing, did not reduce
the incidence of events over a median follow-up of 25
months
• CTA was associated with fewer catheterizations showing
no obstructive CAD than was functional testing (3.4% vs.
4.3%)
• More patients in the CTA group underwent
catheterization within 90 days after randomization
(12.2% vs. 8.1%)
• overall exposure was higher in the CTA group (mean,
12.0 mSv vs. 10.1 mSv; P<0.001)
• multicentre, double-blind trial at four general hospitals in northern Italy.
• 240 pts with recurrent pericarditis assigned to Colchine bid vs. placebo
• colchicine (0.5 mg bid x 6 months if >70 kg or 0.5 mg daily if < 70 kg
• primary outcome was recurrent pericarditis in the intention-to-treat
Conclusions
• PCSK9 inhibitors aid in significant lowering of LDL cholesterol in
patients who respond poorly or are intolerant of statins
• Spironolactone failed to have a meaningful clinical impact on
patients with heart failure with preserved ejection fraction
• Ivabradine and Sacubitril offer new hope for patients suffering from
heart failure with reduced ejection fraction
• Long term monitoring may aid in detection of atrial fibrillation in
patients with cryptogenic stroke
• Novel oral anticoagulants offer wider options for prevention of
stroke/systemic thromboembolism in patients with non-valvular atrial
fibrillation
• Anatomical assessment of coronary artery disease is not superior to
functional assessment in patients with suspected coronary artery
disease
• Oral Colchicine is effective in reducing recurrences of pericarditis
