Plasma N-terminal pro-brain natriuretic peptide and adrenomedullin: new neurohormonal predictors of left ventricular function and prognosis after myocardial infarction.

Arthur Mark Richards, M. G. Nicholls, +9 authors David W Smyth
Circulation
1998

BACKGROUND Newly discovered circulating peptides, N-terminal pro-brain natriuretic peptide (N-BNP) and adrenomedullin (ADM), were examined for prediction of cardiac function and prognosis and… (More)

Neurohumoral changes during onset and offset of ovine heart failure: role of ANP.

MargaretM. Fitzpatrick, M. G. Nicholls, E A Espiner, Hamid Ikram, Philip F. Bagshaw, Timothy G. Yandle
The American journal of physiology
1989

The temporal relationship of changes in atrial natriuretic peptide (ANP) secretion to other pathophysiological changes in heart failure has not been investigated. We studied the hemodynamic,… (More)

Neurohormonal response to head-up tilt and its role in vasovagal syncope.

David Lewis Jardine, Ian C Melton, Ian George Crozier, Sinclair I Bennett, Richard A. Donald, Hamid Ikram
The American journal of cardiology
1997

In a controlled study, 26 patients with a history of recurrent syncope were found to have increased arginine vasopressin, corticotrophin, and atrial natriuretic factor levels after 5 minutes of 60… (More)

The clinical, cardiac, renal, arterial and neurohormonal effects of omapatrilat, a vasopeptidase inhibitor, in patients with chronic heart failure.

Dougal Mcclean, Hamid Ikram, A H Garlick, Arthur Mark Richards, M. G. Nicholls, Ian George Crozier
Journal of the American College of Cardiology
2000

OBJECTIVES We sought to examine the effects of long-term vasopeptidase inhibition in patients with heart failure. BACKGROUND The long-term effects of omapatrilat, an agent that inhibits both… (More)

Specificity of the direct solid-phase radioimmunoassay for detection of hepatitis-B antigen.

Alfred M. Prince, Betsy Brotman, D Jass, Hamid Ikram
Lancet
1973

Haemodynamic effects of beta-adrenergic blockade in hyperthyroid patients with and without heart failure.

Hamid Ikram
British medical journal
1977

Haemodynamic studies were performed in 10 patients with uncomplicated thyrotoxicosis and seven with thyrotoxic cardiac failure. The cardiac output of those with uncomplicated hyperthyroidism was… (More)

RENAL, HAEMODYNAMIC, AND HORMONAL EFFECTS OF HUMAN ALPHA ATRIAL NATRIURETIC PEPTIDE IN HEALTHY VOLUNTEERS

Arthur Mark Richards, M. G. Nicholls, Hamid Ikram, Mark Wi Webster, Timothy G. Yandle, E A Espiner
The Lancet
1985

The effects of atrial natriuretic peptide (ANP) were investigated in six healthy male volunteers taking a constant diet (120 mmol sodium and 60 mmol potassium daily). They were given an intravenous… (More)

Decrease in cardiac output and muscle sympathetic activity during vasovagal syncope.

David Lewis Jardine, Ian C Melton, +4 authors Hamid Ikram
American journal of physiology. Heart and…
2002

The importance of cardiac output (CO) to blood pressure level during vasovagal syncope is unknown. We measured thermodilution CO, mean blood pressure (MBP), and leg muscle mean sympathetic nerve… (More)

Autonomic control of vasovagal syncope.

David Lewis Jardine, Hamid Ikram, Christopher Miles Frampton, Rachell Frethey, Sinclair I Bennett, Ian George Crozier
The American journal of physiology
1998

In the pathophysiological study of vasovagal syncope, the nature of the interaction between baroreceptor sensitivity (BS), sympathetic withdrawal, and parasympathetic activity has yet to be… (More)

Neurohormonal changes after acute myocardial infarction. Relationships with haemodynamic indices and effects of ACE inhibition.

Stephan Foy, Ian George Crozier, +4 authors Hamid Ikram
European heart journal
1995

To determine the neurohormonal response to angiotensin-converting enzyme (ACE) inhibition after acute myocardial infarction, 36 patients presenting within 6 h of the onset of chest pain were studied… (More)
