The role of confirmatory tests in the diagnosis of primary aldosteronism.

Confirmatory tests for diagnosis of primary aldosteronism (PA) play an important role in sparing patients with a false-positive aldosterone-to-renin ratio (ARR) screening test from undergoing invasive subtyping procedures. We recommend that patients with a positive ARR test should undergo at least one confirmatory test to confirm or exclude the diagnosis of PA before directly proceeding to subtype studies, except for patients with significant PA phenotypes, including spontaneous hypokalemia, plasma aldosterone concentration >20 ng/dL plus plasma renin activity below a detectable level. Although a gold standard confirmatory test has not been identified, we recommend that saline infusion test and captopril challenge test, which were widely used in Taiwan. Patients with PA have been reported to have a higher prevalence of concurrent autonomous cortisol secretion (ACS). ACS is a biochemical condition of mild cortisol overproduction from adrenal lesions, but without the typical clinical features of overt Cushing's syndrome. Concurrent ACS may result in incorrect interpretation of adrenal venous sampling (AVS) and may lead to adrenal insufficiency after adrenalectomy. We recommend screening for ACS in patients with PA scheduled for AVS examinations as well as for adrenalectomy. We recommend the 1-mg overnight dexamethasone suppression test as screening method to detect ACS.

Renal Impact of Culprit-Only versus Multi-Vessel Revascularization for Cardiogenic Shock Complicating Acute Myocardial Infarction: Systematic Review and Meta-Analysis.

Background: The optimal strategy of percutaneous coronary intervention (PCI) for acute myocardial infarction (MI) complicated with cardiogenic shock (CS) remains controversial. We aimed to elucidate the renal and cardiovascular impact of culprit-only (C) revascularization versus additional interventions on non-infarct-related arteries. Methods: PubMed, Embase, MEDLINE, and Cochrane Library were searched for relevant literature. A total of 96,812 subjects [C-PCI: 69,986; multi-vessel (MV)-PCI: 26,826] in nine studies (one randomized control trial; eight observational cohort studies) were enrolled. Results: MV-PCI was associated with a higher kidney event rate [relative risk (RR): 1.29, 95% confidence interval (CI): 1.12-1.49; p < 0.001]. However, the all-cause mortality rate was comparable both during admission (RR: 1.07, 95% CI: 0.94-1.22; p = 0.30) and at one year (RR: 0.96, 95% CI: 0.79-1.16; p = 0.65). MV-PCI was associated with a greater risk of stroke (RR: 1.19, 95% CI: 1.08-1.32; p < 0.001) and bleeding events (RR: 1.27, 95% CI: 1.07-1.51; p = 0.006), but reduced risk of recurrent MI (RR: 0.89, 95% CI: 0.82-0.97; p = 0.009) and repeat revascularization (RR: 0.34, 95% CI: 0.16-0.71; p = 0.004). No increased risk of coronary artery bypass grafting was present (RR: 1.09, 95% CI: 0.38-3.17; p = 0.87). Conclusions: C-PCI was associated with a lower rate of renal dysfunction but not all-cause mortality in patients with CS complicating acute MI.

2023 Expert Consensus of the Taiwan Society of Cardiology on the Diagnosis and Treatment of Cardiac Amyloidosis.

Cardiac amyloidosis is one form of systemic amyloidosis caused by abnormal amyloid fibrils deposited in the extracellular space of the myocardium causing heart failure because of restrictive cardiomyopathy and conduction disturbances. The incidence and prevalence of cardiac amyloidosis are higher than previously noted, particularly among special populations. The most common forms of cardiac amyloidosis are light chain and transthyretin amyloid cardiomyopathy. Even though more than 70% of patients with systemic amyloidosis have cardiac amyloidosis, the diagnosis is often delayed, suggesting significant gaps in the knowledge of cardiac amyloidosis and a lack of multidisciplinary teamwork in our daily practice. The Taiwan Society of Cardiology Heart Failure Committee organized experts to draft the "Expert Consensus on the diagnosis and treatment of cardiac amyloidosis." This statement aims to help clinicians and healthcare professionals improve early diagnosis and management of cardiac amyloidosis in Taiwan. The expert panel met virtually to review the data and discuss the consensus statements. Our review provided practical information about diagnostic methods and algorithms, clinical clues and red-flag signs, cardiac amyloidosis per se and its comorbidities treatment modalities, and follow-up plans for asymptomatic transthyretin gene carriers. We especially innovate two acronyms, "HFpEF MUTED CALL" and "HFmrEF MUST COUNT", to help in the early diagnosis and screening of transthyretin amyloid cardiomyopathy as shown in the Central Illustration.

Efficacy of Tafamidis in Patients with Ala97Ser Hereditary Transthyretin Cardiac Amyloidosis: A Six-Month Follow-Up Study.

Background: Hereditary transthyretin amyloid cardiomyopathy (ATTR-CM) is a progressive and fatal disease. A97S (p.Ala117Ser) is the most common transthyretin genetic mutation in Taiwan. Tafamidis is a transthyretin stabilizer, and it has been shown to improve outcomes. However, its effect on A97S ATTR-CM subtypes remains unknown. Objectives: This study aimed to investigate the efficacy of tafamidis in patients with hereditary A97S ATTR-CM after 6 months of treatment. Methods: We retrospectively analyzed ATTR-CM patients who received tafamidis (61 mg/day) treatment at National Taiwan University Hospital. Functional status, biochemistry and echocardiography were measured at baseline and after 6 months of tafamidis treatment. The outcome measure was to compare the N-terminal pro-brain natriuretic peptide (NT-proBNP) level at baseline and after 6 months of tafamidis treatment. Results: Twenty patients were enrolled in this study. Their mean age was 63.0 ± 5.8 years and 75% were men. The baseline left ventricular (LV) mass index was 200.9 ± 63.9 g/m2, and the baseline LV ejection fraction was 58.9 ± 13.5%. After 6 months of treatment, the log NT-proBNP level significantly improved from 2.9 ± 0.6 to 2.7 ± 0.5 (p = 0.036). Subgroup analysis showed that the LV posterior wall thickness and left atrial diameter were significantly higher in the patients with improved NT-proBNP, suggesting the benefits of tafamidis for ATTR-CM patients with severe cardiac involvement. Conclusions: The patients with hereditary A97S ATTR-CM in this study had decreased levels of NT-proBNP after 6 months of tafamidis treatment, and this reduction was especially pronounced in those with more severe cardiac involvement.

The Efficacy and Safety of Short-Term Tolvaptan Usage in Patients with Acute Decompensated Heart Failure.

Background: Patients admitted with acute decompensated heart failure (ADHF) have a poor prognosis and poor quality of life due to dyspnea and edema. Tolvaptan, a vasopressin V2 receptor antagonist, is an effective water diuretic. This study aimed to evaluate the efficacy and safety of a short course of tolvaptan to treat volume overload in patients with ADHF. Methods: We conducted a phase III, multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of a short course of tolvaptan (15 mg/day for 4 days) in hospitalized ADHF patients with volume overload despite the use of conventional diuretics. The primary end-point was the change in body weight after 4 days of treatment. The secondary end-points were the change in intake/output balance, change in serum sodium/potassium concentrations, physician/patient assessed signs and symptoms of heart failure after 4 days of treatment, and all-cause mortality in 1 month. Results: A total of 110 patients were screened, and 91 were randomized to receive 15 mg/day of tolvaptan for 4 days (n = 46) or matching placebo (n = 45). Compared to the placebo-treated patients, tolvaptan significantly reduced body weight (-1.36 ± 2.13 kg in the tolvaptan group vs. -0.59 ± 1.27 kg in the placebo group, p = 0.0394). The tolvaptan group also had a negative intake/urine volume balance compared to the placebo group (-509.3 ± 2788.2 ml vs. 975.5 ± 1903.1 ml, p = 0.0059). The safety profile of tolvaptan was acceptable. Conclusions: Tolvaptan significantly reduced volume overload in hospitalized ADHF patients with volume overload despite the use of conventional diuretics.

Efficacy and safety of balloon pulmonary angioplasty in patients with inoperable chronic thromboembolic pulmonary hypertension.

BACKGROUND: Data on the efficacy and safety of balloon pulmonary angioplasty (BPA) in Taiwanese patients with chronic thromboembolic pulmonary hypertension (CTEPH) are lacking. In this study, we evaluated the effects of BPA on clinical parameters including hemodynamics, echocardiography and functional status in patients with inoperable CTEPH in Taiwan. METHODS: We retrospectively collected the clinical data of inoperable CTEPH patients who underwent ≥3 BPA sessions. Pulmonary hemodynamic parameters of right heart catheterization, echocardiography, 6-min walk distance and World Health Organization (WHO) functional class were collected and analyzed before and after BPA treatment. RESULTS: A total of 59 BPA sessions were performed in 13 inoperable CTEPH patients. No periprocedural deaths or major complications requiring tracheal intubation with mechanical ventilation occurred. WHO functional class significantly improved in all 13 patients (P < 0.001), and 6-min walk distance improved from 344 ± 147 to 450 ± 120 m (P = 0.014). Additionally, the plasma level of N-terminal pro-brain natriuretic peptide significantly decreased (P = 0.007). Hemodynamic data were available in 11 patients after ≥3 BPA sessions. Both mean pulmonary artery pressure and pulmonary vascular resistance significantly decreased from 44.6 ± 11.7 mmHg to 32.6 ± 5.1 mmHg (P = 0.005) and 745 ± 389 dyn·s·cm-5 to 366 ± 120 dyn·s·cm-5 (P = 0.002), respectively. Cardiac output also increased from 3.69 ± 1.12 L/min to 4.33 ± 0.94 L/min (P = 0.021). CONCLUSION: BPA improved both clinical symptoms and hemodynamic data in inoperable CTEPH Taiwanese patients without major periprocedural complications.

The Value of Heart Rhythm Complexity in Identifying High-Risk Pulmonary Hypertension Patients.

Pulmonary hypertension (PH) is a fatal disease-even with state-of-the-art medical treatment. Non-invasive clinical tools for risk stratification are still lacking. The aim of this study was to investigate the clinical utility of heart rhythm complexity in risk stratification for PH patients. We prospectively enrolled 54 PH patients, including 20 high-risk patients (group A; defined as WHO functional class IV or class III with severely compromised hemodynamics), and 34 low-risk patients (group B). Both linear and non-linear heart rate variability (HRV) variables, including detrended fluctuation analysis (DFA) and multiscale entropy (MSE), were analyzed. In linear and non-linear HRV analysis, low frequency and high frequency ratio, DFAα1, MSE slope 5, scale 5, and area 6-20 were significantly lower in group A. Among all HRV variables, MSE scale 5 (AUC: 0.758) had the best predictive power to discriminate the two groups. In multivariable analysis, MSE scale 5 (p = 0.010) was the only significantly predictor of severe PH in all HRV variables. In conclusion, the patients with severe PH had worse heart rhythm complexity. MSE parameters, especially scale 5, can help to identify high-risk PH patients.

Atrial Fibrillation in Primary Aldosteronism.

Primary aldosteronism (PA) is the most common cause of secondary hypertension. Increasing evidence has demonstrated an increased cardiovascular risk in patients with PA compared to those with essential hypertension (EH), including atrial fibrillation (AF), the most prevalent arrhythmia among adults that is associated with an elevated risk of subsequent cerebro-cardiovascular adverse events. The mechanisms of increased prevalence of AF in PA patients are complex. Excessive aldosterone production is regarded to be a key component in the pathogenesis of AF, in addition to arterial hypertension and electrolyte imbalance. In addition, several translational and clinical studies have reported that structural remodeling with atrial fibrosis and electrical remodeling with arrhythmogenicity induced by an excess of aldosterone also play major roles in AF genesis. Clinical studies from several registries and meta-analysis have reported an increased prevalence and risk of AF in PA patients compared to EH patients. Recent trials have further demonstrated a reduction in the risk of new-onset atrial fibrillation (NOAF) after adrenalectomy, while the results of medical treatment with mineralocorticoid receptor antagonists (MRAs) have been inconsistent. This review outlines the current evidence of the relationship between PA and AF, and highlights recent progress in the management of PA with regards to the development of AF.

Riociguat Improves Pulmonary Hemodynamics in Patients with Inoperable Chronic Thromboembolic Pulmonary Hypertension.

BACKGROUND: Few studies have investigated the effects of riociguat on pulmonary hemodynamics in Asian patients with chronic thromboembolic pulmonary hypertension (CTEPH). In this study, we evaluated the effects of riociguat on pulmonary hemodynamics in inoperable CTEPH patients. METHODS: We retrospectively collected the clinical data of 11 inoperable CTEPH patients. Pulmonary hemodynamic parameters of right heart catheterization, echocardiography, 6-minute walk distance and World Health Organization (WHO) functional class were assessed at baseline and after riociguat treatment. RESULTS: The median duration of riociguat treatment was 12 months, and all 11 patients tolerated riociguat 7.5 mg/day well after titration. With regards to pulmonary hemodynamic data, both mean pulmonary artery pressure and pulmonary vascular resistance significantly decreased from 41 ± 8 mmHg to 38 ± 9 mmHg (p = 0.045) and 787 ± 417 dyn·s·cm-5 to 478 ± 267 dyn·s·cm-5 (p = 0.007), respectively. With regards to clinical symptoms, WHO functional class significantly improved in nine of the 11 patients, and there was no change in the other two patients (p = 0.004). In addition, the median level of N-terminal pro-brain natriuretic peptide also significantly decreased from 281 (117-5943) pg/ml to 226 (48-1276) pg/ml (p = 0.021). CONCLUSIONS: Riociguat treatment improved both clinical symptoms and pulmonary hemodynamics in the inoperative CTEPH patients in this study.

Endothelial Dysfunction in Primary Aldosteronism.

Primary aldosteronism (PA) is characterized by excess production of aldosterone from the adrenal glands and is the most common and treatable cause of secondary hypertension. Aldosterone is a mineralocorticoid hormone that participates in the regulation of electrolyte balance, blood pressure, and tissue remodeling. The excess of aldosterone caused by PA results in an increase in cardiovascular and cerebrovascular complications, including coronary artery disease, myocardial infarction, stroke, transient ischemic attack, and even arrhythmia and heart failure. Endothelial dysfunction is a well-established fundamental cause of cardiovascular diseases and also a predictor of worse clinical outcomes. Accumulating evidence indicates that aldosterone plays an important role in the initiation and progression of endothelial dysfunction. Several mechanisms have been shown to contribute to aldosterone-induced endothelial dysfunction, including aldosterone-mediated vascular tone dysfunction, aldosterone- and endothelium-mediated vascular inflammation, aldosterone-related atherosclerosis, and vascular remodeling. These mechanisms are activated by aldosterone through genomic and nongenomic pathways in mineralocorticoid receptor-dependent and independent manners. In addition, other cells have also been shown to participate in these mechanisms. The complex interactions among endothelium, inflammatory cells, vascular smooth muscle cells and fibroblasts are crucial for aldosterone-mediated endothelial dysregulation. In this review, we discuss the association between aldosterone and endothelial function and the complex mechanisms from a molecular aspect. Furthermore, we also review current clinical research of endothelial dysfunction in patients with PA.

Aldosteronism is associated with more severe cerebral small vessel disease in hypertensive intracerebral hemorrhage.

Primary aldosteronism is associated with various types of cardiovascular and cerebrovascular damage independently of hypertension. Although chronic hypertension and related cerebral arteriosclerosis are the main risk factors for intracerebral hemorrhage, the effects of aldosteronism remain poorly understood. We enrolled 90 survivors of hypertensive intracerebral hemorrhage, 21 of them with aldosteronism and 69 with essential hypertension as controls in this study. Clinical parameters and neuroimaging markers of cerebral small vessel disease were recorded, and its correlations with aldosteronism were investigated. Our results showed that the aldosteronism group (55.2 ± 9.7 years, male 47.6%) had similar hypertension severity but exhibited a higher cerebral microbleed count (interquartile range) (8.5 [2.0‒25.8] vs 3 [1.0‒6.0], P = 0.005) and higher severity of dilated perivascular space in the basal ganglia (severe perivascular space [number >20], 52.4% vs. 24.6%, P = 0.029; large perivascular space [>3 mm], 52.4% vs. 20.3%, P = 0.010), compared to those with essential hypertension (53.8 ± 11.7 years, male 73.9%). In multivariate models, aldosteronism remained an independent predictor of a higher (>10) microbleed count (odds ratio = 8.60, P = 0.004), severe perivascular space (odds ratio = 4.00, P = 0.038); the aldosterone-to-renin ratio was associated with dilated perivascular space (P = 0.043) and large perivascular space (P = 0.008). In conclusions, survivors of intracerebral hemorrhage with aldosteronism showed a tendency towards more severe hypertensive arteriopathy than the essential hypertension counterparts independently of blood pressure; aldosteronism may contribute to dilated perivascular space around the deep perforating arteries. Aldosteronism is associated with more severe cerebral small vessel disease in hypertensive intracerebral hemorrhage.

Reversal of arterial stiffness in medically and surgically treated unilateral primary aldosteronism.

OBJECTIVE: Hyperaldosteronism has adverse effects on cardiovascular structure and function. Laparoscopic adrenalectomy is the gold standard for patients with unilateral primary aldosteronism. For unilateral primary aldosteronism patients unable or unwilling to undergo surgery, the effects of mineralocorticoid receptor antagonists (MRAs) on the reversibility of arterial stiffness and other clinical data remain unclear. We aimed to compare the reversibility of arterial stiffness using pulse wave velocity (PWV) and other clinical parameters between surgically and medically treated unilateral primary aldosteronism patients. METHODS: We prospectively enrolled 306 unilateral primary aldosteronism patients, of whom 247 received adrenalectomy and 59 received medical treatment with MRAs. Detailed medical history, basic biochemistry and PWV data were collected in both groups before treatment and 1 year after treatment. After propensity score matching (PSM) for age, sex, SBP and DBPs, 149 patients receiving adrenalectomy and 54 patients receiving MRAs were included for further analysis. RESULTS: After PSM, the patients receiving adrenalectomy had a greater reduction in blood pressure, increase in serum potassium, and change in PWV (ΔPWV, -53 ±â€Š113 vs. -10 ±â€Š140 cm/s, P  = 0.028) than those receiving MRAs 1 year after treatment. Multivariable regression analysis further identified that surgery (compared with MRA treatment), baseline PWV, baseline DBP, the change in DBP and the use of diuretics were independently correlated with ΔPWV. CONCLUSION: Adrenalectomy is superior to MRA treatment with regards to vascular remodeling when treating unilateral primary aldosteronism patients.

Tafamidis improves myocardial longitudinal strain in A97S transthyretin cardiac amyloidosis.

Background: Transthyretin cardiomyopathy (ATTR-CM) is a debilitating disease that has received much attention since the emergence of novel treatments. The Transthyretin Cardiomyopathy Clinical Trial showed that tafamidis, a transthyretin tetramer stabilizer, effectively reduced the declines in functional capacity and quality of life. However, Ala97Ser (A97S) hereditary ATTR-CM is underrepresented in major ATTR-CM tafamidis trials. Objectives: We aim to investigate the change in global longitudinal strain (GLS) of A97S ATTR-CM patients after 12 months of tafamidis treatment. Methods: We retrospectively analysed a prospective cohort of patients with A97S ATTR-CM who received tafamidis meglumine (61 mg/day) at the National Taiwan University Hospital. Echocardiography with speckle tracking strain analysis was performed at baseline and 12 months after treatment. Results: In all, 20 patients were included in the cohort. The baseline left ventricular ejection fraction (LVEF) and interventricular septum (IVS) thickness were 59.20 ± 13.23% and 15.10 ± 3.43 mm, respectively. After 12 months of tafamidis treatment, the LVEF and IVS were 61.83 ± 15.60% (p = 0.244) and 14.59 ± 3.03 mm (p = 0.623), respectively. GLS significantly improved from -12.70 ± 3.31% to -13.72 ± 3.17% (p = 0.048), and longitudinal strain (LS) in apical and middle segments significantly improved from -16.05 ± 4.82% to -17.95 ± 3.48% (p = 0.039) and -11.89 ± 4.38% to -13.58 ± 3.12% (p = 0.039), respectively. Subgroup analysis showed that patients with LVEF < 50% had a better treatment response and improvement in GLS. The patients with an IVS ⩾ 13 mm had an improvement in two-chamber LS from -10.92 ± 4.25% to -13.15 ± 3.87% (p = 0.042) and an improvement in apical left ventricular LS from -15.30 ± 5.35% to -17.82 ± 3.99% (p = 0.031). Conclusion: Tafamidis significantly improved GLS, and particularly apical and middle LS in A97S ATTR-CM patients.

Tafamidis improves myocardial longitudinal strain in A97S transthyretin cardiac amyloidosis Transthyretin cardiomyopathy (ATTR-CM) is a severe heart condition that has gained attention due to recent advancements in treatments. One of these treatments, called tafamidis, has been shown to be effective in maintaining heart function and quality of life. However, there has been limited research on a specific genetic variation of ATTR-CM: A97S. Our aim was to determine whether A97S ATTR-CM patients experienced improved heart function after one year of tafamidis treatment. We conducted this study at the National Taiwan University Hospital, where we enrolled 20 A97S ATTR-CM patients. We used echocardiography to evaluate their heart function, focusing on a parameter called global longitudinal strain. The results showed that after one year of tafamidis treatment, these patients experienced a significant improvement in their global longitudinal strain, particularly in the apical and middle regions of the heart. In conclusion, tafamidis appears to be beneficial for A97S ATTR-CM patients by enhancing their heart's global longitudinal strain, which is a positive sign for their cardiac health.

Recent progress in unraveling cardiovascular complications associated with primary aldosteronism: a succinct review.

This comprehensive review offers a thorough exploration of recent advancements in our understanding of the intricate cardiovascular complications associated with Primary Aldosteronism (PA). PA encompasses a spectrum of conditions characterized by hypertension and excessive production of aldosterone operating independently of the renin-angiotensin system. Given its association with an elevated risk of cardiovascular and cerebrovascular complications, as well as a higher incidence of metabolic syndrome in comparison to individuals with essential hypertension (EH), an accurate diagnosis of PA is of paramount importance. This review delves into the intricate interplay between PA and cardiovascular health and focuses on the key pathophysiological mechanisms contributing to adverse cardiac outcomes. The impact of different treatment modalities on cardiovascular health is also examined, offering insights into potential therapeutic approaches. By highlighting the significance of recognizing PA as a significant contributor to cardiovascular morbidity, this review emphasizes the need for improved screening, early diagnosis, and tailored management strategies to both enhance patient care and mitigate the burden of cardiovascular diseases. The findings presented herein underscore the growing importance of PA in the context of cardiovascular medicine and emphasize the potential for translating these insights into targeted interventions to improve patient outcomes.

Use of Technetium-99m-Pyrophosphate Single-Photon Emission Computed Tomography/Computed Tomography in Monitoring Therapeutic Changes of Eplontersen in Patients With Hereditary Transthyretin Amyloid Cardiomyopathy.

BACKGROUND: Hereditary transthyretin amyloid cardiomyopathy (hATTR-CM) is a progressive and fatal disease. Recent evidence indicates that bone scintigraphy may serve as a tool to monitor the effectiveness of hATTR-CM treatment. The objective of this study was to examine how eplontersen therapy influences the semiquantitative uptake of technetium-99m-pyrophosphate in individuals diagnosed with hATTR-CM. METHODS AND RESULTS: We retrospectively analyzed a prospective cohort from the NEURO-TTRansform trial, including patients with hATTR-CM receiving eplontersen (45 mg/4 weeks). A control group comprised patients with hATTR-CM who had not received eplontersen, inotersen, tafamidis, or patisiran. Technetium-99m-pyrophosphate single-photon emission computed tomography/computed tomography was conducted at baseline and during follow-up. Thirteen patients with hATTR-CM were enrolled, with 6 receiving eplontersen and 7 serving as the control group. The median follow-up time was 544 days. The eplontersen group exhibited a significant decrease in volumetric heart and lung ratio (3.774 to 2.979, P=0.028), whereas the control group showed no significant change (4.079 to 3.915, P=0.237). Patients receiving eplontersen demonstrated a significantly greater reduction in volumetric heart and lung ratio compared with the control group (-20.7% versus -3.4%, P=0.007). CONCLUSIONS: The volumetric heart and lung ratio used to quantify technetium-99m-pyrophosphate uptake showed a significant reduction subsequent to eplontersen treatment in individuals diagnosed with hATTR-CM. These findings suggest the potential efficacy of eplontersen in treating hATTR-CM and highlight the value of technetium-99m-pyrophosphate single-photon emission computed tomography/computed tomography as a tool for monitoring therapeutic effectiveness.

Anatomical and functional remodeling of left ventricle in patients with primary aldosteronism and concomitant albuminuria.

Background: Primary aldosteronism (PA) is the leading cause of secondary hypertension globally and is associated with adverse cardiovascular outcomes. However, the cardiac impact of concomitant albuminuria remains unknown. Objective: To compare anatomical and functional remodeling of left ventricle (LV) in PA patients with or without albuminuria. Design: Prospective cohort study. Methods: The cohort was separated into two arms according to the presence or absence of albuminuria (>30 mg/g of morning spot urine). Propensity score matching with age, sex, systolic blood pressure, and diabetes mellitus was performed. Multivariate analysis was conducted with adjustments for age, sex, body mass index, systolic blood pressure, duration of hypertension, smoking, diabetes mellitus, number of antihypertensive agents, and aldosterone level. A local-linear model with bandwidth of 2.07 was used to study correlations. Results: A total of 519 individuals with PA were enrolled in the study, of whom 152 had albuminuria. After matching, the albuminuria group had a higher creatinine level, at baseline. With regard to LV remodeling, albuminuria was independently associated with a significantly higher interventricular septum (1.22 > 1.17 cm, p = 0.030), LV posterior wall thickness (1.16 > 1.10 cm, p = 0.011), LV mass index (125 > 116 g/m2, p = 0.023), and medial E/e' ratio (13.61 > 12.30, p = 0.032), and a lower medial early diastolic peak velocity (5.70 < 6.36 cm/s, p = 0.016). Multivariate analysis further revealed that albuminuria was an independent risk factor for elevated LV mass index (p < 0.001) and medial E/e' ratio (p = 0.010). Non-parametric kernel regression also demonstrated that the level of albuminuria was positively correlated with LV mass index. The remodeling of LV mass and diastolic function under the presence of albuminuria distinctly improved after PA treatment. Conclusion: The presence of concomitant albuminuria in patients with PA was associated with pronounced LV hypertrophy and compromised LV diastolic function. These alterations were reversible after treatment for PA. Plain language summary: Cardiac Impact of Primary Aldosteronism and Albuminuria Primary aldosteronism and albuminuria has been, respectively, demonstrated to bring about left ventricular remodeling, but the aggregative effect was unknown. We constructed a prospective single-center cohort study in Taiwan. We proposed the presence of concomitant albuminuria was associated with left ventricular hypertrophy and compromised diastolic function. Intriguingly, management of primary aldosteronism was able to restore these alterations. Our study delineated the cardiorenal crosstalk in the setting of secondary hypertension and the role of albuminuria for left ventricular remodeling. Future interrogations toward the underlying pathophysiology as well as therapeutics will facilitate the improvement of holistic care for such population.
