Methods and ResultsPlasma levels of aldosterone, BNP, and angiotensin-converting enzyme were measured in anterior interventricular vein (AIV), coronary sinus (CS), and aortic root (Ao), respectively, in 20 patients with left ventricular systolic dysfunction (LVSD), 25 patients with LV diastolic dysfunction (LVDD), and 23 control subjects. Aldosterone levels were significantly higher in AIV and CS than Ao in LVSD (98±10 versus 72±9 pg/mL, P<0.001, and 97±11 versus 72±9 pg/mL, P<0.001, respectively) and LVDD (87±10 versus 71±9 pg/mL, P<0.01, and 84±10 versus 71±9 pg/mL, P<0.01, respectively) groups, but no differences were observed in levels for these sites in the control group. Levels of ACE activity and BNP also were higher in AIV than Ao in both LV dysfunction groups. The difference in aldosterone levels between AIV and Ao and those in BNP and angiotensin-converting enzyme had a significant positive correlation with LVEDP and a significant negative correlation with LV ejection fraction in the LVSD group.
ConclusionsProduction of aldosterone, angiotensin-converting enzyme, and BNP are activated in failing human ventricle in proportion to severity.

Recently, some workers reported that aldosterone is produced also in extra-adrenal tissues, including heart and blood vessels, in animals.6 7 8 9 10 However, whether aldosterone is produced in human heart, particularly in failing heart, is unknown.
Coronary sinus drains blood from the heart as a whole, and the anterior interventricular vein (AIV), which lies in the anterior interventricular groove, drains blood from the anterior left ventricle (LV).11 Therefore, the difference in hormone level between AIV and aortic root reflects the level of hormone from the LV, and that between the coronary sinus and aortic root reflects hormone level from the whole heart. By the use of this method, we showed that production of A-type (ANP), and B-type (BNP) natriuretic peptides was activated in the LV in patients with heart failure.12 13 14 15 We also showed by use of this method that angiotensin-converting enzyme (ACE) activity from LV is increased in patients with LV dysfunction (LVD).15
The present study was designed to examine whether aldosterone is produced in addition to ACE and BNP in hearts of patients with LVD. We measured plasma levels of aldosterone together with those of BNP and serum ACE.

4 days before study. The control group comprised 23 patients (15 men and 8 women; mean age, 60.0±3.0 years; age range, 23 to 78 years) in whom diagnostic cardiac catheterization, including coronary angiography and left ventriculography, was performed. Twenty control patients had atypical chest pain with normal coronary angiograms, and 3 patients had stable angina pectoris. None had myocardial infarction, cardiac hypertrophy, other heart muscle diseases, electrolyte disturbance, renal impairment (serum creatinine >2.0 mg/mL), or hypertension.
The study protocol was in agreement with the guidelines of the ethics committee at our institution, and written informed consent was obtained from each patient before study, including consent for withholding of medication.
Cardiac Catheterization Study
Cardiac catheterization was performed in the morning,
with patients in a fasting state. Hemodynamic measurements, including
pulmonary artery pressure, pulmonary capillary wedge pressure, right
atrial pressure, and cardiac output, were performed with a Swan-Ganz
catheter inserted into the femoral or subclavian vein. Cardiac output
was determined by use of the thermodilution technique in triplicate.
After right heart catheterization was completed, a 6F Goodale-Lubin
catheter was placed in the coronary sinus through a brachial
vein.
The catheter was then advanced into the AIV fluoroscopically by use of a guidewire.12 13 14 15 Position of catheter tip in AIV was confirmed by injection of contrast dye medium. Patients in whom at least the proximal half of the AIV was not visualized were excluded from study. A Judkins catheter was placed at the root of the aorta by way of the femoral artery. Blood was sampled within 2 minutes at the aortic root, AIV, and coronary sinus. Care was taken to draw blood samples slowly from the AIV. Initial parts of the sample, including those forcibly drawn, were discarded, because forcible drawing of blood from the AIV resulted in spurious levels of hormone, probably because backflow from the coronary sinus occurred and contaminated the AIV.11 12
Systemic arterial pressure, heart rate, and LVEDP were measured, and coronary arteriography and left ventriculography were performed. LVEF was determined by left ventriculograms.
Hormonal Analysis
Plasma levels of aldosterone were measured in
duplicate by commercially available radioimmunoassay kits (SPAC-S
aldosterone kit; Dainabot
Inc).16 The minimal
detectable quantity of aldosterone was 25 pg/mL. Intra-assay and
interassay coefficients of variation were 4.7% and 4.5%,
respectively. Serum ACE activity was measured in duplicate by
colorimetry using commercially available kits (ACE color; Fujirebio
Inc).17 Intra-assay and
interassay coefficients of variation by this method were 6.7% and
8.3%, respectively. Plasma levels of BNP were measured with a specific
immunoradiometric assay for human BNP (Shionoria BNP kit; Shionogi) as
reported previously.18
Minimal detectable quantity of human BNP is 4 pg/mL. Intra-assay and
interassay coefficients of variation were 5.3% and 5.9%,
respectively.
Statistical Analysis
All values are expressed as mean±SE. Statistical
significance was defined as a probability value <0.05. Unpaired
t test or 1-way ANOVA was used
to analyze results of hemodynamic or hormonal
measurements.19 Hormonal
levels at the aortic root, AIV, and coronary sinus within each group
were compared with 2-way ANOVA with repeated measurements followed by
Scheffés test. Correlation of plasma levels of aldosterone and BNP
as well as serum levels of ACE activity with hemodynamic parameters
were examined by use of linear regression
analysis.

|
In the LVSD group, plasma levels of aldosterone were significantly higher in AIV and coronary sinus than aortic root (98±10 versus 72±9 pg/mL, P<0.001, and 97±11 versus 72±9 pg/mL, P<0.001, respectively), whereas no difference existed in levels between AIV and coronary sinus. Plasma aldosterone levels in the LVSD group were significantly higher in AIV (98±10 versus 58±6 pg/mL; P<0.001) and coronary sinus (97±11 versus 62±7 pg/mL; P<0.01) than in the control group.
In the LVDD group, plasma levels of aldosterone were significantly higher in AIV and coronary sinus than aortic root (87±10 versus 71±9 pg/mL, P<0.01, and 84±10 versus 71±9 pg/mL, P<0.01, respectively), whereas levels were not different between AIV and coronary sinus. Plasma levels of aldosterone in the LVDD group were significantly higher in AIV (87±10 versus 58±6 pg/mL; P<0.01) and coronary sinus (84±10 versus 62±7 pg/mL; P<0.01) than in controls. On the other hand, no significant differences were seen in plasma aldosterone levels among aortic root, AIV, and coronary sinus (61±7, 58±6, and 62±7 pg/mL, respectively) in the control group.
In the LVSD group, serum ACE activity was significantly higher in AIV and coronary sinus than in aortic root (13.2±0.7 versus 11.9±0.6 pg/mL, P<0.001, and 13.1±0.7 versus 11.9±0.6 pg/mL, P<0.001, respectively), whereas levels were not significantly different between AIV and coronary sinus. ACE activity levels were significantly higher in AIV (13.2±0.7 versus 10.6±0.7 pg/mL; P<0.01) and coronary sinus (13.1±0.7 versus 10.8±0.8 pg/mL; P<0.01) compared with controls. In the LVDD group, serum ACE activities were not significantly different for every sampling point, and levels were not different from those of the control group. No significant difference existed in ACE activity among the aortic root, AIV, and coronary sinus (10.7±0.7, 10.6±0.7, and 10.8±0.8 pg/mL, respectively) in the control group.
In the LVSD group, plasma BNP levels were significantly higher in AIV and coronary sinus than aortic root (673±121 versus 232±58 pg/mL, P<0.001, and 694±127 versus 232±58 pg/mL, P<0.001), whereas levels were not different between AIV and the coronary sinus. Plasma BNP levels in the LVSD group were significantly higher in aortic root (232±58 versus 20±2 pg/mL, P<0.001), AIV (673±121 versus 74±13 pg/mL, P<0.001), and coronary sinus (694±127 versus 79±15 pg/mL, P<0.001) versus the control group. In the LVDD group, plasma levels of BNP were significantly higher in AIV and coronary sinus than aortic root (215±72 versus 78±9 pg/mL, P<0.001, and 200±65 versus 78±9 pg/mL, P<0.001, respectively), with levels not different between AIV and coronary sinus. Plasma levels of BNP in the LVDD group tended to be higher at every sampling point compared with those of the control group. In the control group, plasma levels of BNP were significantly higher in AIV and coronary sinus than aortic root (74±13 versus 20±2 pg/mL, P<0.001, and 79±15 versus 20±2 pg/mL, P<0.001), whereas levels were not different between AIV and coronary sinus.
Correlation of Cardiac Hormones With
Hemodynamic Parameters
The difference in plasma aldosterone levels between the
AIV and the aortic root (
Aldo [AIV-Ao], where Ao indicates aortic
root) had a significant negative correlation with LVEF and a
significant positive correlation with LVEDP in the LVSD group
(Figure 2
, left). On the other hand, the
Aldo (AIV-Ao) had
no significant correlation with either LVEF or LVEDP in the LVDD group
(Figure 3
, left).
|

The difference in serum ACE activity (
ACE [AIV-Ao]) had
a significant negative correlation with LVEF and a significant positive
correlation with LVEDP in the LVSD group
(Figure 2
, center) but no correlation with either LVEF or
LVEDP in the LVDD group
(Figure 3
, center).
The difference in plasma BNP levels (
BNP [AIV-Ao]) had
a significant negative correlation with LVEF and a significant positive
correlation with LVEDP in the LVSD group
(Figure 2
, right). In the LVDD group,
BNP (AIV-Ao) had
only a weakly significant correlation with LVEDP
(Figure 3
, right).
Correlations Among Cardiac Aldosterone, ACE
Activity, and BNP
In the LVSD group,
Aldo (AIV-Ao) had a significant
positive correlation with
ACE (AIV-Ao) but no correlation with
BNP (AIV-Ao)
(Figure 4A
). A significant positive correlation occurred
between
ACE (AIV-Ao) and
BNP (AIV-Ao)
(Figure 4A
).
|
In the LVDD group,
Aldo (AIV-Ao) had a significant
positive correlation with
ACE (AIV-Ao), whereas it had no
correlation with
BNP (AIV-Ao)
(Figure 4B
) as in the LVSD group. A significant positive
correlation occurred between
ACE (AIV-Ao) and
BNP (AIV-Ao)
(Figure 4B
).

The present study also showed that levels of serum ACE activity were increased significantly between AIV and aortic root in failing hearts with systolic dysfunction but not significantly in failing hearts with diastolic dysfunction or control hearts. These results are in agreement with those of our previous studies15 and indicate that ACE production also was activated in failing ventricles of humans with systolic dysfunction. However, the absolute differences in ACE activity between AIV and aortic root were small, which indicates that the biological function of cardiac ACE is mainly autocrine, paracrine, or both.
On the other hand, differences in BNP levels between AIV and aortic root were highly significant in failing ventricles with systolic dysfunction as well as failing ventricles with diastolic dysfunction and control hearts. This indicates that the heart is the main source of BNP production and the endocrine organ for circulating BNP. These results are in agreement with those of our previous studies.13 14 15 22
The exact mechanism for induction of aldosterone into the failing heart is not clear. Aldosterone synthesis is mainly stimulated by angiotensin II, the active peptide of renin-angiotensin system, but its production is also controlled by potassium, adrenocorticotropic hormone, and natriuretic peptides, including ANP and BNP.23 24 25 26 27 28 In the present study, levels of aldosterone had a highly significant positive correlation with levels of ACE activity in failing ventricles. This result suggests that increased activity of local ACE, causing conversion of angiotensin I to angiotensin II, may stimulate production of aldosterone in failing hearts in a paracrine or autocrine manner. Indeed, Silvestre and coworkers10 recently showed that cardiac aldosterone is activated in rat heart with myocardial infarction and that this is mediated primarily by cardiac angiotensin II. They further showed that aldosterone synthase mRNA was elevated in infarcted rat ventricles.10
Cardiac aldosterone, ACE, and BNP had significant positive correlations with LVEDP and significant negative correlations with LVEF in patients with LVSD. These results are in agreement with those of our previous studies13 14 15 22 and suggest that increased wall tension or stretch in the dilated ventricles may be a main stimulus for activation of cardiac aldosterone as well as ACE and BNP production in ventricles with systolic dysfunction. On the other hand, no significant correlation was found between cardiac hormones and LVEDP except cardiac BNP, which had a weak correlation with LVEDP in patients with isolated LVDD. The results indicate that systolic dysfunction is more important than diastolic dysfunction for activation of cardiac aldosterone as well as ACE and BNP in failing hearts.
No significant correlation existed between levels of aldosterone and BNP in failing ventricles. This result probably is due to the fact that aldosterone production is stimulated by angiotensin II but suppressed by natriuretic peptides (ANP and BNP) in failing hearts.23 24 25 26 27 28 We and others have shown that ANP and BNP directly suppress aldosterone production.25 26 27 28
Clinical Implications
Aldosterone was originally thought to be important in
the pathophysiology of heart failure only because of its ability to
increase sodium retention and potassium loss. However, Weber et
al4 and Young et
al5 have shown that
aldosterone promotes myocardial and vascular fibrosis independent of
the hemodynamic effects. Aldosterone also causes direct vascular damage
and baroreceptor dysfunction and prevents uptake of norepinephrine by
the
myocardium.4 29 30
Recently, Pitt and
coworkers31 showed that
blocking aldosterone with a low dose of spironolactone substantially
reduced the risks of morbidity and mortality among patients with severe
heart failure (RALES trial). Efficacy of an aldosterone blockade in
their trial does not appear to be due entirely to prevention of
sodium retention or potassium loss.
The present study shows that aldosterone production is activated in failing ventricles of humans. Concentration of aldosterone within the heart is reported to greatly exceed circulating concentrations.9 Thus, cardiac aldosterone may play an important role in the pathophysiology of heart failure, and aldosterone receptor antagonists may ameliorate heart failure by blocking the action of locally produced aldosterone in failing heart.
Conclusions
We conclude that the production of aldosterone, in
addition to ACE and BNP, is activated in failing human ventricles in
proportion to severity, particularly of systolic
dysfunction.
