The body has a remarkable capacity to heal itself
Cada 29 de septiembre, el Día Mundial del Corazón nos recuerda que las enfermedades cardiovasculares —silenciosas y extendidas— no son inevitables. Los factores de riesgo son conocidos: tabaquismo, diabetes, obesidad, hipertensión. Lo que transforma ese conocimiento en destino es la decisión cotidiana de moverse, comer con conciencia y consultar a un médico. El corazón no pide gestos heroicos, sino hábitos sostenidos.
- Las enfermedades cardiovasculares siguen siendo la principal causa de muerte en el mundo, muchas veces sin avisar hasta que el daño ya está hecho.
- El sedentarismo, la mala alimentación y el tabaquismo crean una tormenta silenciosa que el cuerpo acumula durante años antes de manifestarse.
- Expertos proponen seis estrategias concretas —ejercicio aeróbico, entrenamiento de fuerza, HIIT, dieta balanceada, abandono del tabaco y supervisión médica— como escudo preventivo accesible para casi cualquier persona.
- Quienes ya tienen antecedentes cardíacos o factores de riesgo pueden revertir parte del daño: a los quince años de dejar de fumar, el riesgo coronario se iguala al de alguien que nunca fumó.
- Reconocer las señales de alarma —dolor en el pecho, falta de aire, sudor frío, pérdida de conciencia— y actuar de inmediato puede ser la diferencia entre un susto y una tragedia.
Las enfermedades cardiovasculares no son una sola condición sino una familia: presión arterial elevada, arritmias, insuficiencia cardíaca. Llegan con frecuencia sin anunciarse, pero en muchos casos son prevenibles. Esa es la promesa detrás del Día Mundial del Corazón, celebrado cada 29 de septiembre: lo que hacemos hoy moldea lo que nuestro corazón hará mañana.
Israel Tejeda, líder técnico de Smart Fit Perú, propone seis estrategias probadas. La base es el ejercicio aeróbico: caminar, pedalear, bailar, trotar durante treinta a sesenta minutos. El cuerpo responde volviéndose más eficiente y el corazón se fortalece. El entrenamiento de alta intensidad por intervalos complementa ese trabajo, obligando al corazón a adaptarse mediante ráfagas cortas de esfuerzo máximo. El entrenamiento de fuerza, por su parte, mejora la composición corporal, reduce la presión arterial y combate la pérdida muscular que trae la edad.
La alimentación importa tanto como el movimiento. Frutas, verduras, granos integrales y proteínas magras deben ocupar el centro del plato; las grasas saturadas, el sodio y los azúcares añadidos, los márgenes. Quienes ya padecen alguna enfermedad cardíaca necesitan un plan diseñado por un especialista.
Antes de comenzar cualquier rutina de ejercicio, especialmente con antecedentes familiares o condiciones previas, es indispensable consultar a un médico y contar con supervisión profesional en las primeras semanas. Y sobre el tabaco, los números hablan solos: cinco años después de dejarlo, el riesgo de enfermedad coronaria cae un 39%; a los quince años, se iguala al de quien nunca fumó.
Finalmente, hay señales que no admiten espera: dolor en el pecho, dificultad para respirar, debilidad repentina, mareos, sudor frío o pérdida de conciencia. Reconocerlas y pedir ayuda de inmediato convierte una posible catástrofe en una historia de supervivencia.
Cardiovascular disease is not one condition but a family of them—high blood pressure that strains the arteries, irregular heartbeats that throw off the body's rhythm, the slow failure of the heart muscle itself. These diseases kill quietly and widely, often arriving unannounced. But they are also, in many cases, preventable. That is the message behind World Heart Day, observed each year on September 29th, a date set aside to remind people that what they do today shapes what their heart will do tomorrow.
The risk factors are familiar by now: smoking, diabetes, obesity, high blood pressure. They are not mysteries. What matters is what comes next—the decision to move, to eat differently, to see a doctor. Israel Tejeda, a technical leader at Smart Fit Peru, outlines six concrete strategies that work.
Aerobic exercise is the foundation. This means moving the large muscle groups of the body at low to moderate intensity for thirty to sixty minutes at a time. A walk, a bike ride, a jog, a hike, dancing—these are not exotic interventions. They are available to almost anyone. The body responds by becoming more efficient at using oxygen, by strengthening the heart itself.
High-intensity interval training takes a different approach. Short bursts of hard work alternate with recovery periods, pushing the body to use more oxygen than it normally would, forcing the heart to adapt and grow stronger. Strength training—lifting weights, using machines, working against your own body weight—does something different still. It improves how the body is composed, lowers blood pressure, and fights sarcopenia, the progressive weakening of skeletal muscle that comes with age and inactivity.
Diet matters as much as movement. The prescription is straightforward: fruits, vegetables, whole grains, lean proteins, eggs, nuts. The things to avoid are equally clear—saturated and trans fats, high sodium, added sugars. Pizza, ice cream, hamburgers are not forbidden forever, but they belong at the margins, not the center. If someone already has heart disease, a specialist should design their diet specifically.
Before starting any exercise program, especially if there is a family history of heart problems or an existing condition, a person should see a doctor. A trained trainer should supervise the early weeks, ensuring the progression is gradual and safe. This is not caution for its own sake; it is the difference between building strength and causing harm.
Smoking deserves its own category. Five years after quitting, the risk of coronary disease drops by thirty-nine percent. At fifteen years, the risk falls to the level of someone who never smoked at all. The body has a remarkable capacity to heal itself, but only if given the chance.
Finally, there are the warning signs that demand immediate attention: chest pain, shortness of breath, sudden weakness, numbness or tingling in the arms, dizziness, nausea, pain in the jaw or shoulder or back or stomach, cold sweat, loss of consciousness. These are not symptoms to wait out. They are signals to call for help. Recognizing them and acting fast is the difference between a scare and a catastrophe.

Regular exercise is one of the best things a person can do for their heart, but those with preexisting conditions or family history should consult a specialist before beginning— Israel Tejeda, Smart Fit Peru
A Conversa do Hearth Outra perspectiva sobre a história
Why does World Heart Day exist if we already know what causes heart disease?
Because knowing and doing are different things. The day is a reminder, a moment when people stop and think about choices they make every single day without thinking at all.
So it's not about new discoveries.
No. It's about old truths that people forget or ignore. Smoking, exercise, diet—we have known these matter for decades. The point is to say it again, clearly, so that someone reading it might actually change something.
What's the hardest part for most people?
Probably consistency. A person can do aerobic exercise once. They can eat well for a week. The challenge is making it a life, not an event. That is why having a trainer, seeing a doctor, building a routine—these things matter. They create structure.
And if someone already has a family history of heart disease?
Then they should not guess or experiment. They should see a specialist before they start exercising hard, before they change their diet dramatically. A doctor can tell them what their specific risk is and what their specific plan should be.
Is there any point at which it's too late to quit smoking?
No. Even at fifteen years after quitting, the body has recovered almost completely. The risk falls to the level of someone who never smoked. That is remarkable. It means the body is always willing to heal if you stop damaging it.
