4a) So let's ✅what u know!
— cardio-met (@cardiomet_CE) November 3, 2025
1⃣ Which statement best reflects the global impact of poorly controlled #HTN?
A. It affects < 100 million adults worldwide
B. It is the leading preventable cause of #CV death
C. It mainly affects high-income countries
D. Global control rates > 60%
4c) 3⃣ In the #BaxHTN trial, how did #baxdrostat’s blood pressure #BP-lowering effect in pts with #CKD compare to those without CKD?
— cardio-met (@cardiomet_CE) November 3, 2025
A. Significantly less benefit in CKD
B. Similar benefit in both groups
C. Only effective in non-CKD
D. Increased adverse events, no benefit
6a) There are differences in terminology amongst the various guidelines around terms such as #resistant, #refractory, or #uncontrolled #HTN pic.twitter.com/yTyA1Otj8T
— cardio-met (@cardiomet_CE) November 3, 2025
6c) This term is broader than #resistant HTN; includes pts where control is possible but requires intensive management due to factors like suboptimal adherence, lifestyle challenges, frequent med changes, or exacerbating conditions (eg #obesity, sleep apnea, high salt intake).
— cardio-met (@cardiomet_CE) November 3, 2025
7) This matters in #nephrology, as
— cardio-met (@cardiomet_CE) November 3, 2025
👉#CKD pts have ⤵️BP targets & ⬆️complications w/uncontrolled BP
👉 Resistant/uncontrolled HTN accelerates kidney function loss
👉Definitions guide when to escalate tx, involve multidisciplinary teams, or look for treatable secondary causes.
8b) So still uncontrolled despite those PLUS often an #MRA = trouble, no matter what definition is used, as long as optimal or maximally tolerated doses and at the appropriate dosing frequency are in use
— cardio-met (@cardiomet_CE) November 3, 2025
9a) Using the definition of #resistant #HTN (let's call it #RH) in 6a ⤴️, in a cohort study of 205,750 pts with incident HTN, it was reported that the risk of CV outcomes was higher in patients with RH, with a hazard ratio of 1.47 (95% CI 1.33 to 1.62).

10a) Pts with #RH have up to 50% increased risk of #CV events, 46% increased risk of #HF, 24% increased risk of ischemic cardiac events, 32% increased risk of #ESRD, 14% increased risk of #stroke, and 6% increased risk of premature death.
— cardio-met (@cardiomet_CE) November 3, 2025
10c) Pts with RH do have a higher prevalence of comorbid conditions, including #diabetes, #OSA, #CKD, ischemic heart disease, & stroke, which can themselves also greatly ⬆️CV morbidity and mortality
— cardio-met (@cardiomet_CE) November 3, 2025
10e) #RH is a complex pathophysiologic state with contributions from (1) sodium retention, (2) #aldosterone excess, (3) low #renin states, and (4) activation of the #RAAS. See https://t.co/RavEU42H19 pic.twitter.com/K70V8HVh8D
— cardio-met (@cardiomet_CE) November 3, 2025
11b) #Aldosterone excess is related to being overweight or obese, as adipocytes can directly secrete aldosterone or indirectly stimulate the release of aldosterone secretagogues.
— cardio-met (@cardiomet_CE) November 3, 2025
This can lead to further sodium & fluid retention.https://t.co/3YS2vlkpqw
11d) The combination of low renin and #aldosterone #dysregulation is common, resulting in resistant HTN:

12b) #Spironolactone has been shown to be the best 4th line agent at reducing #BP in pts with #RH, as shown in the Prevention & Treatment of Hypertension With Algorithm based therapY-2 (PATHWAY-2) trial.

Laboratory monitoring (K+, Na+, renal function) is warranted for pts taking #spironolactone.

In an attempt to bypass the aldosterone escape effect, aldosterone synthase became a target of interest
