The Heart - The Most Powerful Organ in Our Body? | DW Documentary

Why It Matters

The documentary highlights hidden cardiovascular risks and gender gaps, urging individuals and policymakers to prioritize early detection and lifestyle interventions to reduce heart disease mortality.

Key Takeaways

• Heart disease risk differs markedly between men and women.
• Silent heart attacks often lack obvious symptoms, delaying treatment.
• LDL cholesterol and triglycerides drive plaque, while HDL protects.
• Genetic Lp(a) levels cannot be lowered by diet or exercise.
• Regular cardiac imaging and stress tests reveal hidden cardiovascular issues.

Summary

The DW documentary “The heart – The most powerful organ in our body?” uses personal stories, medical commentary, and visual exams to illustrate how the heart drives both emotion and survival, while exposing common misconceptions about cardiovascular health.

Dr. Konita Ruiz Monet explains that the heart begins beating within weeks of conception and works tirelessly, yet risk factors such as smoking, poor diet, high LDL cholesterol, triglycerides, and especially genetically‑determined lipoprotein (a) can silently erode arterial walls. The film contrasts classic male heart‑attack symptoms—severe chest pain radiating to the arm—with the subtler signs women often experience, like nausea, fatigue, or shortness of breath, which lead to delayed emergency care.

Real‑life cases bring the data to life: twins Naomi and Joelle undergo cardiac ultrasounds and stress tests that reveal normal function but differing lipid profiles; cyclist Faruchio recounts a silent heart attack at age 38 and the subsequent stenting of 80 % blocked arteries; paramedic Selen Kian demonstrates first‑aid steps, emphasizing rapid compression and airway management.

The film’s takeaway is clear: proactive screening—including cholesterol panels, Lp(a) testing, and exercise stress tests—combined with lifestyle changes and mental‑health support can prevent catastrophic events. Recognizing gender‑specific symptom patterns and the limits of diet on genetic risk factors pushes both clinicians and the public toward more personalized, preventive cardiac care.

Original Description

The heart is the most unusual muscle in our body. It works tirelessly, begins beating in the womb and can even continue functioning when the brain fails. Yet, when we’re young, we barely pay any attention to it.

29-year-old twins Naomi and Joëlle Karfich are active, have healthy diets and feel fit. But when it comes to their hearts, they don’t have much to go on. They’re unaware of any potential genetic risks or how their heart health has been measured up to now. That’s why they’ve come to see Conchita Ruiz-Mohné, in Cologne.

The cardiologist is an expert in female cardiovascular medicine, a field that has long been neglected. Women's hearts differ from men's, and often present subtler heart attack symptoms. This can lead to dangerously late diagnoses. Every minute counts in a heart attack: as soon as the blood supply stops, heart tissue begins to die, irretrievably.

Paramedic Celine Kilian shows how to respond quickly and correctly in the event of a heart attack. This is knowledge that may very well come in handy one day: Heart attacks are the most common cause of death in Germany. Younger people are increasingly affected - especially younger men, under 40.

Ferruccio Labita, who had a heart attack at the age of 38, is one of them. Today, he trusts his heart again - and is a passionate competitive cyclist. But he’s learned never to exceed his own physical limits.

One major risk factor is stress. Chronic interpersonal stress can cause heart disease - even leading to what’s known as "broken heart syndrome". Christiane Waller explains why the hormone oxytocin can play a protective role here.

Freediver Anna Karina Schmitt shows how to combat stress with breathing. She uses specific exercises to prepare her heart for dives to depths of up to 80 meters - using just one breath.
