4) #Cardiovascular disease in patients with #CKD is more frequent, more severe, & has different manifestations compared w/ the non-CKD population➡️high economic & societal burden.
6) ... sudden cardiac death, cardiac valve disease, arterial calcification, and hemorrhagic stroke. Either ischemic or non-ischemic cardiac diseases present in CKD patients are characterized by evolving to chronic congestive heart failure (HF) (i.e., cardiorenal syndrome type 4).
7) Of note, the⬆️death rates associated with all stages of CKD might reflect accelerated rates of both atherosclerosis & HF . . . but pts w/primary 🫀 disease & #HF can experience secondary ⬇️kidney function. Both can coexist based on shared risk factors or systemic disorders.

Heart failure in chronic kidney disease: conclusions from a Kidney Disease: Improving Global Outcomes (KDIGO) Controversies Conference - PubMed
The incidence and prevalence of heart failure (HF) and chronic kidney disease (CKD) are increasing,...

10) So now let's establish some definitions so that we are all speaking in the same terms. First, #heartfailure, from 🔓escardio.org:
12) The latter markers include albuminuria, urine sediment abnormalities, histological, or structural abnormalities.
And #CKD is graded in stages, allowing us to know that we are comparing 🍎to 🍎:

13) So what do you know? What is the approximate prevalence of moderate to severe kidney impairment (defined as a #GFR < 60 mL/min per 1.73 m2) in patients with #heartfailure?
14) Different databases tell us different numbers, but the best answer is ~ 30-60 percent. In a systematic review of 16 studies of > 80,000 hosp and non-hosp pts with HF, moderate to severe kidney impairment (eGFR < 53 mL/min, serum creat > 1.5 mg/dL+, or ...
15) ...serum cystatin C > 1.56 mg/dL+ ) was present in 29% of pts. In the Acute Decompensated Heart Failure National Registry (ADHERE) database of > 100,000 pts w/HF req'ing hospitalization, ~30% had #CKD (defined as serum creat > 2.0 mg/dL).
17) In different series, ~ 20-30% of patients developed ⬆️serum creat > 0.3 mg/dL. In one report, 24% had⬆️of 0.5 mg/dL+. Risk factors for worsening kidney function during admission for HF include which of the following? ANSWER BEFORE SCROLLING ⬇️!
18) It's d, prior history of HF or diabetes & uncontrolled #hypertension, and also an admission serum creatinine of 1.5 mg/dL or higher. The⬆️in serum creat usually occurs in the first 3-5 days of hospitalization. It is known that 1/2 - 2/3 of pts w/HF present with eGFR < 60, ...
19) ... w/ a greater prevalence in those with more severe symptoms & a stepwise⬆️in mortality risk with ⬇️ eGFR. The epidemiological figures of HF in patients initially identified as having CKD are not so well known. 🤔

22) So we have been drinking from the firehose here . . . let's take a break. PLEASE RETURN TOMORROW for more education on the looming dual epidemics of #CKD and #HF! Nods to @ValleAlfonso @GoggleDocs @mvaduganathan @SantosGallegoMD @gcfmd @BiykemB @kevin_damman @P_Rossing
23) WELCOME BACK! We're talking about the unfortunately parallel⬆️s in incidence #HF & #CKD, while you earn🆓CE/#CME taught by @drahmedmohsen85 🇪🇬. 👏to @AgarwalRajivMD @ErinMichos @ShelleyZieroth @EzequielZaidel @robmentz @edgarvlermamd @nephondemand @VietHeartPA
24) Whereas the worldwide incidence of de novo #HF in the general population does not exceed 1%, the incidence in known #CKD is ~ 17% - 21%. Bad things go together!

25) It gets even worse for pts w/ #ESKD. Evidence ➡️ in pts undergoing #hemodialysis & in pts S/P #kidneytransplant, the vascular access may be a risk factor for HF as high AV fistula flow is assoc'd w/LVH, LV dilatation, &⬇️#LVEF, + #PAH & #RV dysfunction.
26) In addition, through its effect as a left-to-right extracardiac shunt, the arteriovenous fistula can increase cardiac workload substantially, & in some pts ➡️high-output state & resultant HF over time.

27) What about #prognosis? The presence of #HF ⬇️survival among patients both w/ & w/o #CKD, but more so with CKD (p-value for interaction <0.0001). See 🔓pubmed.ncbi.nlm.nih.gov
29) It's HFrEF . . . and the association of CKD with mortality in HFrEF is independent of age, functional class, duration of HF, hemoglobin, or diabetes mellitus. See 🔓pubmed.ncbi.nlm.nih.gov
31) Hence, the ADQI XI Workgroup proposed a new definition of structural cardiac disease in #HF for pts w/ #CKD, namely for patients with #ESRD, according to the presence of at least 1⃣of 8⃣ #echocardiographic alterations (🔓pubmed.ncbi.nlm.nih.gov).
32) So that's #echo. What about lab values? How do we interpret #Natriuretic_Peptide (NP) levels in pts w/ #CKD?
CKD is one among the numerous causes of elevated NPs that may weaken their diagnostic utility in HF. See 🔓pubmed.ncbi.nlm.nih.gov.
CKD is one among the numerous causes of elevated NPs that may weaken their diagnostic utility in HF. See 🔓pubmed.ncbi.nlm.nih.gov.
33) Current data➡️cause of elevated NP concentrations in advanced CKD is multifactorial, representing in part a true counter-regulatory response from the heart to the kidney--not only ⬇️passive renal clearance, as only 25% clearance of NPs is related to renal filtration.
34) Indeed, 2 recent studies➡️pts w/advanced #CKD + #HF w/⬆️#BNP have very low #neprilysin activity & postulated that BNP is a potent endogenous neprilysin inhibitor. See 🔓pubmed.ncbi.nlm.nih.gov & 🔓pubmed.ncbi.nlm.nih.gov.
35) To maintain optimal diagnostic performance, the cut-off concentrations for detecting HF may need to be ⬆️when eGFR is <60. With strong correlation between renal dysfunction & age, no additional adjustment seems necessary for NT-proBNP once using age-adjusted rule-in cut-offs.
36) For BNP, effect of renal dysfunction overall is smaller, & ⬆️the rule-out cut-off to 200 pg/mL rather than 100 pg/mL seems sufficient. Due to incomplete data, NP testing for #HF should be discouraged in pts on dialysis.
