Heart Disease

Heart disease is often pictured as a disease afflicting middle-aged to older adults who already have a long history with health problems. However, the truth is that heart disease is increasingly affecting younger people. Hospitalizations and deaths due to heart disease for adults under 40 are increasing at an astonishing rate. 

Key Factors

One of the biggest reasons for this increase in heart disease rates is lifestyle. Many young people are living sedentary lifestyles, often spending much of the day sitting in a chair. This lack of cardio activity can cause blood pressure to rise, putting more strain on the heart and increasing the chance of developing a heart condition. Poor diet, especially diets consisting mostly of fast food or processed food, also contribute to heart disease due to causing early-onset type 2 diabetes, high cholesterol levels, and obesity, all of which are big risk factors for heart disease. According to the CDC, 1 in 5 adolescents in the US are obese, and approximately 1 in 6 have high blood pressure. Both of these conditions damage the heart and its arteries over time, culminating in heart disease. 

In addition to lifestyle, stress is also a major factor in heart disease. Young people today are reporting higher levels of stress due to academic, financial, and social pressures compared to past generations. Chronic stress eventually leads to inflammation and high cortisol levels, which left unchecked harms the heart and cardiovascular health.  

Substance abuse also is a big-time contributor to the elevated levels of heart disease among youth today. Stimulants such as vaping and cocaine cause elevated heart rates, which over time can cause the heart muscle to become too thick, and impair heart function. Even excessive caffeine consumption at an extreme level will cause damage to the heart. Genetic conditions such as congenital heart disease or familial hypercholesterolemia (high cholesterol levels) also greatly increase the risk of getting heart disease.

How to Prevent Heart Disease

Young people can prevent heart disease by making healthy choices early on. Regular exercise is important to maintain proper cardiovascular health. In addition, try to limit processed and fast food consumption, and avoid smoking or vaping. Stress management is important to ensure cortisol levels are in check, and getting enough sleep is also helpful. It is important to go to annual checkups with your physician to make sure that everything is alright; this step is especially important if you have a family history of heart conditions. These simple habits can help protect the heart for life. 

Raising awareness for heart disease for all ages is crucial. Being empowered with knowledge about heart disease now is crucial so that heart disease can be prevented before it even begins.
