3. PIONEER-HF results:
likely a “game-changer”
Dr. Eric Velazquez
presented the PIONEER-HF study, which compared initiation of
sacubitril-valsartan, an angiotensin receptor-neprilysin inhibitor (ARNI), to
that of enalapril in patients who were hospitalized with decompensated heart
failure and had a left ventricular ejection fraction ≤40 percent. Those treated
with ARNI had a significant reduction in time-averaged NT-proBNP levels when
compared to subjects treated with enalapril (see below). Provocatively, while
the trial was not powered for hard clinical endpoints, ARNI use also led to a
significant reduction in heart failure rehospitalization. UT Southwestern was a
clinical trial site in PIONEER-HF. These data add to the observations from the
landmark PARADIGM-HF trial by: 1) extending the use of sacubitril-valsartan to
the inpatient setting; 2) suggesting that a run-in phase to demonstrate
tolerability of full-dose ACE-inhibitors is not necessary before administration
of ARNI therapy; and 3) providing confirmatory evidence to the results seen in
PARADIGM-HF. It is my suspicion that PIONEER-HF, though not a large phase 3
trial, might very well change clinical practice.
4. Dr. Eugene Braunwald
recounts an early experience that influenced his decision to study aortic
stenosis
The legendary Dr.
Eugene Braunwald recounted an experience that contributed to his decision to
investigate the natural history of aortic stenosis. Specifically, more than 50
years ago he was asked what would happen to a patient who had severe aortic
stenosis yet was free of symptoms. He recognized that neither he, nor anyone
else in the world, knew the answer to this fundamentally critical question, so
he set out to answer it. This line of investigation culminated in his landmark
1968 publication in Circulation in which he demonstrated that
symptom-onset marks a downward inflection point in survival; this manuscript
includes arguably one of the most recognizable Figures in all of cardiovascular
medicine. Dr. Braunwald advised those in the room to keep our eyes open for
such important clinical questions that arise about our patients. He noted that
if physicians don’t stay alert for such observations they will “just float by.”
Powerful advice from a giant in the field, and relevant to all who care for any
patient in any discipline.
5. Impressive presence
of UT Southwestern Internal Medicine residents
Shown are eight of the 10 UT Southwestern
Internal Medicine (IM) residents who presented their work at the AHA Scientific
Sessions. This large complement of IM residents presenting at one of the
premier cardiovascular meetings – if not the premier CV meeting – in the world
is truly amazing. Further, it speaks to the high caliber of the trainees we
are fortunate to work with at UT Southwestern. The future of cardiovascular
medicine is bright!
