Understanding angina symptoms at night

An episode that wakes you, appears without exertion, becomes more frequent or differs from your established pattern can signal a change that requires urgent clinical judgment.

Angina may feel like pressure, squeezing, heaviness or tightness, with possible spread to the arm, shoulder, jaw, back or upper abdomen. Breathlessness, sweating or nausea may accompany it. Symptoms at rest are clinically different from a predictable pattern brought on only by exertion.

Reflux, chest-wall pain, anxiety and lung problems can also disturb sleep with chest discomfort. Timing alone cannot distinguish them. Details such as body position, meals, movement, breathing, duration and response to prescribed medicine help the clinician assess the pattern.

Stop any activity, sit upright and follow your personal angina action plan if one has been prescribed. Use rapid-relief medicine only according to its instructions. Do not borrow another person's medicine or take extra doses outside your plan.

After a non-emergency episode, document the time, sensation, duration, possible meal or activity trigger, accompanying symptoms and medicine response. Arrange a prompt review rather than waiting for the next routine visit, particularly if nighttime episodes are new.

Call UAE emergency services for new or severe chest pressure, symptoms that persist or return, or discomfort with marked breathlessness, cold sweating, nausea, faintness, or pain spreading to the arm, jaw, shoulder or back. Follow your prescribed emergency plan while help is coming.

Do not wait until morning when the episode feels different from previous angina or does not improve as expected after prescribed medicine. Avoid driving yourself because symptoms can worsen on the way.

Ask whether the timing suggests a changed angina pattern, whether your medicine schedule needs review, and what testing is appropriate. Confirm the exact action to take if another episode occurs and whether sleep, reflux or breathing symptoms need separate evaluation.
