JACC Associate Editor Theresa McDonagh, MBBCH speaks with author Akshay S. Desai, MD, FACC about this paper on pulse pressure published in JACC and presented at AHA. In a pooled analysis of 16,950 patients with chronic HFmrEF or HFpEF enrolled from 4 global randomized clinical trials, a J-shaped relationship was observed between SBP and the risk of adverse CV events, with the lowest risk occurring at SBP values between 120 and 130 mmHg. A similar pattern was seen with PP, with the lowest risk found between 50 and 60 mmHg. Both higher SBP and higher PP independently predicted adverse CV events. Notably, PP remained a strong predictor of CV risk, independent of baseline SBP.

Join Dr. Harlan Krumholz and Dr. Milton Packer as they discuss the groundbreaking SUMMIT trial, a study poised to redefine treatment for heart failure with preserved ejection fraction (HFpEF) linked to obesity. Dive into the trial's unique methodology, compelling results, and transformative implications for patient care.

Harlan Krumholz, editor-in-chief of JACC, provides a wrap-up of the JACC papers at the AHA Scientific Sessions in Chicago in 2024. JACC's Obesity Revolution page features various trials to provide perspectives on obesity, including SUMMIT, LookAHEAD, and SELECT. Other studies featured include the DANGER trial; REALIZE-K; AMPLATZER; HELIOS-B; a study on sedentary behaviors from the UK Biobank; systolic pressure and blood pressure in patients with HFpEF; rural and urban differences in cardiovascular mortality from 2010-2022; and the association of hospital cardiologist integration with patient outcomes

JACC Associate Editor Michelle M. Kittleson, MD, PhD, FACC, interviews author Mikhail Kosiborod, MD, FACC about his REALIZE-K study published in JACC and presented at AHA. In participants with HFrEF and hyperkalemia, SZC led to large improvements in the percentage of participants with normokalemia while on optimal spironolactone dose, and reduced risk of hyperkalemia and down-titration/discontinuation of spironolactone. More participants had HF events with SZC than placebo; this difference was limited to those with very high NTproBNP levels.

JACC Associate Editor Marc P. Bonaca, MD, FACC, speaks with author Subodh Verma, MD, PhD, and A. Michael A. Lincoff, MD, FACC, about this brief report published in JACC and presented at AHA. Following CABG surgery there remains a markedly high risk of persistent ischemic events, heart failure, and mortality. Semaglutide consistently reduced all cardiovascular outcomes in this population.

JACC Associate Editor Neha J. Pagidipati, MD, FACC, speaks with author Christopher M. Kramer, MD, FACC about this substudy of the SUMMIT trial published in JACC and presented at AHA, demonstrating that tirzepatide therapy in obesity-related HFpEF led to reduced LV mass and paracardiac adipose tissue as compared to placebo and the change in LV mass paralleled weight loss. These physiologic changes may contribute to the reduction in heart failure events seen in the main SUMMIT trial.

JACC: Associate Editor Michelle M. Kittleson, MD, PhD, FACC, talks with authors Scott Solomon, MD, FACC and. Marianna Fontana, MD, about their study published in JACC and presented at AHA. Outpatient worsening heart failure (HF) (oral diuretic intensification or initiation) is simple to assess and has been shown to be prognostic of mortality in patients with ATTR-CM. In this pre-specified analysis of a contemporary ATTR-CM population, patients with outpatient worsening HF had an increased risk of all-cause mortality and CV events and all-cause mortality, as well as greater deterioration in assessments of functional capacity, health status, and quality of life. Vutrisiran significantly reduced the risk of outpatient worsening HF and the composite of outpatient worsening HF, all-cause mortality, and recurrent CV events compared with placebo.

JACC Deputy Editor Erica S. Spatz, MD, FACC, joins author Rishi Wadhera, MD, to discuss his paper on rural and urban differences in cardiovascular mortality in the United States, and the impact of the COVID-19 pandemic.
