Journal ArticleDOI
Continuous positive airway pressure for central sleep apnea and heart failure.
T. Douglas Bradley,Alexander G. Logan,R. John Kimoff,Frédéric Sériès,Debra Morrison,Kathleen A. Ferguson,Israel Belenkie,Michael Pfeifer,John A. Fleetham,Patrick Hanly,Mark Smilovitch,George Tomlinson,John S. Floras +12 more
TL;DR: Although CPAP attenuated central sleep apnea, improved nocturnal oxygenation, increased the ejection fraction, lowered norepinephrine levels, and increased the distance walked in six minutes, it did not affect survival and the data do not support the use of CPAP to extend life in patients who have central sleep Apnea and heart failure.
Journal ArticleDOI
High prevalence of unrecognized sleep apnoea in drug-resistant hypertension.
Alexander G. Logan,Sandra M. Perlikowski,Andrew Mente,András Tislér,Ruzena Tkacova,Mitra Niroumand,Richard S. T. Leung,T. Bradley +7 more
TL;DR: The extraordinarily high prevalence of OSA in adult patients with drug- resistant hypertension supports its potential role in the pathogenesis of drug-resistant hypertension, and justifies the undertaking of a randomized controlled trial to corroborate this hypothesis.
Journal ArticleDOI
Suppression of Central Sleep Apnea by Continuous Positive Airway Pressure and Transplant-Free Survival in Heart Failure A Post Hoc Analysis of the Canadian Continuous Positive Airway Pressure for Patients With Central Sleep Apnea and Heart Failure Trial (CANPAP)
Michael Arzt,John S. Floras,Alexander G. Logan,R. John Kimoff,Frédéric Sériès,Debra Morrison,Kathleen A. Ferguson,Israel Belenkie,Michael Pfeifer,John A. Fleetham,Patrick Hanly,Mark Smilovitch,Clodagh M. Ryan,George Tomlinson,T. Douglas Bradley +14 more
TL;DR: The results suggest that in heart failure patients, CPAP might improve both left ventricular ejection fraction and heart transplant–free survival if CSA is suppressed soon after its initiation.
Journal ArticleDOI
Fall in mean arterial pressure and fetal growth restriction in pregnancy hypertension: a meta-analysis
P. von Dadelszen,Melanie Ornstein,Shelley B. Bull,Alexander G. Logan,Gideon Koren,Laura A. Magee +5 more
TL;DR: Treatment-induced falls in maternal blood pressure may adversely affect fetal growth, and new data are urgently needed to elucidate the relative maternal and fetal benefits and risks of oral antihypertensive drug treatment of mild-to-moderate pregnancy hypertension.

TL;DR: In the diagnosis and assessment of hypertension, automated office blood pressure, taken without patient-health provider interaction, is now recommended as the preferred method of measuring in-office blood pressure as mentioned in this paper.
