Angina and blood pressure

Blood pressure and angina can influence each other, so symptoms and readings should be assessed together rather than separately. High pressure increases the heart's workload, while pressure that is too low may reduce coronary blood flow or cause dizziness, weakness, and faintness.

Angina is discomfort caused when the heart muscle is not receiving enough oxygen-rich blood for its needs. Hypertension can make the heart pump against greater resistance and can contribute to artery damage over time. A blood pressure reading, however, cannot confirm or exclude angina.

Blood pressure may rise temporarily during pain or anxiety. It may fall because of dehydration, illness, or medicines used for angina and hypertension. The meaning of a reading therefore depends on symptoms, your usual range, medication timing, and the clinical setting.

Take blood pressure while seated and rested, using the cuff and technique recommended by your healthcare team. Keep a log of the reading, pulse, time, symptoms, recent activity, and when medicines were taken. Bring the log and medicine list to your appointment.

Continue prescribed treatment unless a clinician advises a change. Do not double a missed dose or adjust angina or blood pressure tablets in response to a single home reading. Contact your clinician if readings repeatedly differ from your personal target or if dizziness, weakness, or chest discomfort follows a dose.

Call UAE emergency services for severe, new, worsening, or resting chest pressure, or discomfort that persists despite following your prescribed angina plan. Breathlessness, fainting, cold sweating, confusion, new weakness, or pain spreading to an arm, the jaw, shoulder, or back also requires emergency assessment.

Seek emergency help for chest symptoms even if the blood pressure monitor shows a reading you consider normal. Likewise, a concerning reading accompanied by collapse, neurological symptoms, or severe chest discomfort should not be managed by taking extra medicine at home.

Ask for your personal home blood pressure target, when to repeat a reading, and which symptoms override the number and require urgent care. Review whether any medicine may be lowering pressure excessively, how to handle missed doses, and whether an ECG or medication adjustment is needed for recurring angina.
