The impact of stress on the heart: the story of one pressure

«"I'm 38, my heart is healthy, but something is wrong"»
Alexey, a middle manager. All his life without diagnoses, without sick leave. But a few months ago he began to notice: his heart "accelerates" for no reason, his blood pressure jumps at night, he wakes up with heaviness in his chest. Examinations did not show a heart attack, his blood vessels are clean. The therapist advised him to see a psychotherapist. But Alexey felt: it was not just his head — something is really happening in the body.
Cardiologist: "This is what a stress cardioreaction looks like"«
When a patient complains of chest pain and the angiogram is normal, I think about autonomic dysfunction, transient ischemia, or stress-induced cardiomyopathy. The heart can function without organic disorders, but react to excess cortisol, adrenaline, hypersympathetic activation.
What exactly happens in the heart during stress?
Vasoconstriction → increased blood pressure
Increased heart rate → tachycardia, arrhythmia
Release of glucose and fats into the blood → accelerated aging of blood vessels
Decreased insulin sensitivity → metabolic load
Hypercoagulation → risk of thrombosis
Chronic stress keeps the heart in good condition readiness to "escape"«, even when the body is asleep.
The story continues: "In the third month I had an attack"«
It was a normal trip to work. My heart was pounding, I felt scared, my hands were clammy. «This is a heart attack,» thought Alexey. He was taken to the hospital. Diagnosis: Takotsubo cardiomyopathy, or broken heart syndrome.
Doctor's comment:
This syndrome occurs more often after a strong emotional shock. Physically, there is a transient violation of the contraction of the left ventricle. On the ECG, there are changes similar to a heart attack. But the arteries are clean. The heart seems to be «tired» from the release of hormones.
What did they do for Alexei?
Appointed β-blockers, that reduce the response to adrenaline
Offered psychotherapy with a CBT component
Taught to use breathing techniques
Heart rhythm was monitored for 14 days (Holter)
Moderate physical activity was introduced, caffeine was eliminated
Added magnesium and cortisol control in dynamics
After 3 months, Alexey regained his sleep, his heart rate stabilized. He continued to work, but learned to notice body signals earlier.
What everyone who experiences "emotions in the chest" should know«
Not all heart symptoms are heart attacks. But cannot be ignored
Stress has physiological effect: changes hormones, metabolism, rhythm
If the examination is «normal» but the heart is «screaming» – it’s not imagination
Hormone cortisol, adrenaline, insulin — tests that should be done
Depression and anxiety can have somatic manifestations, including cardio
Lifestyle changes are not an alternative to therapy, but a part of it.

Diagnostic checklist for suspected stress-induced cardiac stress
ECG at rest and under stress
24/48 hour Holter monitoring
Heart ultrasound (echocardiography)
Tests: cortisol (morning and evening), lipid profile, glucose, HOMA-IR
Heart rate variability (HRV) is an indicator of autonomic balance
Cardiologist consultation due to psycho-emotional stress
This experience is not unique. And it is not about a sick heart, but about sensitive heart, which reacts when a person ignores their own needs for too long.
