Direct Arterial Pressure and the Electrocardiogram in Unrestricted Patients with Angina Pectoris
Key result
Continuous 24-hour monitoring in 8 males with angina pectoris revealed that 27 of 29 angina episodes were accompanied by a rise in both arterial pressure and heart rate.

Implication
No practice change from this case series; hypothesis-generating for pressure-rate product thresholds in ischemia.

Type
Observational (n=8)
Structured PICO
P
Population
8 males with angina pectoris who underwent 24-hour continuous recording of direct arterial pressure and electrocardiogram.
E
Exposure
24-hour ambulatory monitoring of direct arterial pressure and electrocardiogram
O
Outcome
Changes in arterial pressure, heart rate, and ST-segment during angina episodessurrogate
Angina episodes are consistently preceded or accompanied by increases in arterial pressure and heart rate, suggesting a critical pressure-rate product threshold for ischemia.
Limitations
- A limited number of observations were made on the effect of glyceryl trinitrate and β-adrenergic receptor blocking drugs.
Cite This Study
Littler et al. (1973) conducted an observational in Angina Pectoris (n=8). Continuous monitoring of direct arterial pressure and electrocardiogram was evaluated on Hemodynamic and electrocardiographic changes during angina episodes. Continuous 24-hour monitoring in 8 males with angina pectoris revealed that 27 of 29 angina episodes were accompanied by a rise in both arterial pressure and heart rate.
