Abstract

Background— Sympathetic activation has been implicated in the development of left ventricular hypertrophy (LVH). However, the relationship between sympathetic activation and LV mass (LVM) has not been clearly defined across a range of arterial pressure measurements. The present study was planned to determine that relationship, using cardiac magnetic resonance imaging to accurately quantify LVM, in hypertensive patients with and without LVH and in normal subjects. Methods and Results— Twenty-four patients with uncomplicated and untreated essential hypertension (LVH[−]) were compared with 25 patients with essential hypertension and left ventricular hypertrophy (LVH[+]) and 24 normal control subjects. Resting muscle sympathetic nerve activity was quantified as multiunit bursts and single units. Cardiac magnetic resonance imaging–determined LVM was indexed to body surface area (LVM index); in the LVH[−] group, LVM index was 67±2.1 g/m 2 , a value between those of the LVH[+] (91±3.4 g/m 2 ) and normal control (57±2.2 g/m 2 ) groups, respectively. The sympathetic activity in the LVH[−] group (53±1.3 bursts per 100 cardiac beats and 63±1.6 impulses per 100 cardiac beats) was between (at least P <0.001) those of the LVH[+] (66±1.7 bursts per 100 cardiac beats and 77±2.2 impulses per 100 cardiac beats) and normal control (39±3.0 bursts per 100 cardiac beats and 45±3.4 impulses per 100 cardiac beats) groups. Significant positive correlation existed between sympathetic activity and LVM index in the LVH[−] and LVH[+] groups (at least r =0.76, P <0.0001) but not in the normal control group. However, no consistent relationship existed between arterial blood pressure and sympathetic activity or LVM index. Conclusions— These findings further support the hypothesis that central sympathetic activation is associated with the development of LVH in human hypertension.

  • Microneurographic studies almost universally show that sympathetic nerve traffic is potentiated in established hypertension in middle age and in elderly as well as young patients.

    “As far as the second issue is concerned, microneurographic studies almost universally shown that sympathetic nerve traffic is potentiated in established hypertension in middle age and in elderly as well as young patients38–46.”
  • Adrenergic neural factors may contribute to the development and progression of target organ damage, as documented by pronounced increases in sympathetic nerve traffic and cardiac norepinephrine spillover rate in patients with hypertension complicated by left ventricular hypertrophy or left ventricular diastolic dysfunction.

    “Adrenergic neural factors may also contribute to the development and progression of target organ damage, as documented by the pronounced increase in sympathetic nerve traffic and cardiac norepinephrine spillover rate in patients in which hypertension is complicated by left ventricular hypertrophy or left ventricular diastolic dysfunction40,42,44,45.”
  • The sympathetic neural outflow is commonly activated also to the heart and skeletal muscle vasculature, but renal sympathetic activation is central to hypertension pathogenesis.

    “The sympathetic neural outflow is commonly activated also to the heart, shown with selective cardiac norepinephrine spillover measurements28, and to the skeletal muscle vasculature, demonstrated with microneurographic nerve traffic recording32,33,38–46, but it is the renal sympathetic activation which is central to hypertension pathogenesis96–97.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
