800 VALIANTA Healthy Heart Is More Than Just Good Cholesterol
Cholesterol is a type of fat found in your blood that is essential for the proper functioning of your body. It plays an important role in the formation of cell membranes and the production of hormones, vitamin D, and bile acids that help digest food. However, too much cholesterol in your blood can lead to a buildup of plaque in your arteries, which can increase your risk of heart disease and stroke.
Maintaining a healthy heart is crucial for overall health and wellbeing. Your heart is responsible for pumping blood throughout your body and providing vital nutrients and oxygen to your organs and tissues. A healthy heart can reduce the risk of developing various chronic diseases, including cardiovascular disease, diabetes, and high blood pressure.
Unfortunately, there are many misconceptions about what it takes to maintain a healthy heart. For years, the focus has been solely on lowering cholesterol levels to reduce the risk of heart disease. While controlling cholesterol levels is important, it's not the only factor that affects heart health. There are other lifestyle factors that can contribute to a healthy heart, such as exercise, healthy diet, stress management, and getting enough sleep.
In this article, we will explore why a healthy heart is more than just good cholesterol and examine some common misconceptions about heart health. We will also provide practical tips and advice on how to keep your heart healthy and reduce your risk of heart disease. So, let's dive in and discover what it takes to achieve optimal heart health.
The Cholesterol Myth
Cholesterol is a waxy substance found in every cell of our body and is essential for many physiological processes, such as building cell membranes and producing hormones. However, excess cholesterol can accumulate in the walls of arteries, leading to atherosclerosis, a major risk factor for heart disease. For many years, the focus on heart health has been on reducing cholesterol levels, particularly low-density lipoprotein (LDL) or "bad" cholesterol, as it was believed to be the primary cause of heart disease.

Is the "good" vs "bad" cholesterol distinction is misleading?
However, recent research has challenged the idea that LDL cholesterol is the sole contributor to heart disease. In fact, some studies have shown that high-density lipoprotein (HDL) or "good" cholesterol may not be as protective as once thought. For instance, a study published in The Lancet in 2019 found that individuals with genetically high levels of HDL cholesterol did not have a reduced risk of heart disease.
Moreover, the distinction between "good" and "bad" cholesterol is overly simplistic and does not accurately reflect the complexity of cholesterol metabolism. LDL cholesterol, for example, is not inherently bad but serves an essential function in transporting cholesterol to cells throughout the body. Instead, it is the particle size and density of LDL cholesterol that may play a more significant role in heart disease risk.
Alternative measures of heart health beyond cholesterol levels
There are many other factors that contribute to heart disease risk beyond cholesterol levels. For example, inflammation is thought to play a crucial role in the development of atherosclerosis and subsequent heart disease. High levels of C-reactive protein (CRP), a marker of inflammation, have been associated with an increased risk of heart disease.
Other factors that may impact heart health include blood pressure, blood sugar levels, body weight, physical activity levels, and diet. For instance, a diet high in processed foods, added sugars, and saturated fats has been linked to an increased risk of heart disease. On the other hand, diets rich in whole grains, fruits, vegetables, and lean protein sources have been associated with a reduced risk of heart disease.
The Importance of Blood Pressure
Blood pressure is the force of blood against the walls of the arteries as the heart pumps it around the body. It is measured in millimeters of mercury (mmHg) and given as two numbers: systolic pressure, which is the pressure when the heart beats, and diastolic pressure, which is the pressure when the heart rests between beats. Normal blood pressure is considered to be around 120/80 mmHg. However, if blood pressure consistently measures higher than this, it can put a strain on the heart and blood vessels, increasing the risk of heart disease and stroke.
High blood pressure, or hypertension, is a major risk factor for heart disease because it damages the walls of the arteries, making them less elastic and narrowing them. This makes it harder for blood to flow through the vessels, putting a strain on the heart and increasing the risk of heart attack, stroke, and other cardiovascular diseases.
There are several lifestyle changes that can help manage high blood pressure, including:
Eating a healthy diet:
A diet rich in fruits, vegetables, whole grains, lean protein, and low-fat dairy products can help lower blood pressure.
Reducing sodium intake:
Consuming too much sodium can raise blood pressure. It is recommended that adults aim for no more than 2,300 milligrams of sodium per day.
Losing weight:
Being overweight or obese increases the risk of high blood pressure. Losing weight can help lower blood pressure.
Engaging in regular physical activity:
Regular exercise can help lower blood pressure and improve overall cardiovascular health.
The Role of Exercise
As any cardiology clinic in Dubai would be quick to tell you, exercise is an important factor in maintaining a healthy heart. It strengthens the heart muscle, making it more efficient at pumping blood around the body. Exercise can also help reduce inflammation, improve circulation, and lower blood pressure and cholesterol levels. According to the American Heart Association, regular physical activity can reduce the risk of heart disease by up to 35%.
While any type of physical activity can have benefits for heart health, some types of exercise are particularly beneficial. Aerobic exercise, such as brisk walking, running, swimming, or cycling, can help improve cardiovascular fitness and lower the risk of heart disease. Resistance training, such as weightlifting or bodyweight exercises, can also have benefits for heart health by improving muscle strength and endurance.
The American Heart Association recommends that adults engage in at least 150 minutes of moderate-intensity aerobic exercise or 75 minutes of vigorous-intensity aerobic exercise per week, spread out over at least three days. In addition, adults should engage in muscle-strengthening activities at least two days per week. It is important to talk to a healthcare provider before starting a new exercise program, especially if there are any underlying health conditions.
DIET
Diet plays a crucial role in heart health. Certain foods can contribute to the development of heart disease, while others can help prevent it. A heart-healthy diet is one that is low in saturated and trans fats, cholesterol, salt, and added sugars, and high in whole grains, fruits, vegetables, lean proteins, and healthy fats such as omega-3 fatty acids. Speaking to a nutritionist in Dubai can help with understanding your own personal dietary requirements and creating a plan that is tailored to your specific tolerances.

Snack: Greek yogurt with fresh fruit and a drizzle of honey; whole grain crackers with sliced cheese
Dinner: baked salmon with lemon and herbs, served with roasted asparagus and brown rice; side salad with mixed greens, cherry tomatoes, cucumber, and a vinaigrette dressing
How stress affects heart health
Stress can contribute to the development of heart disease by causing inflammation, raising blood pressure, and increasing the risk of unhealthy behaviors such as overeating, smoking, and excessive alcohol consumption. Chronic stress can also lead to an overactive sympathetic nervous system, which can increase heart rate and blood pressure over time.
To manage stress and promote relaxation, it is important to find techniques that work for you. This can include practicing deep breathing exercises, yoga, meditation, progressive muscle relaxation, or other relaxation techniques. Regular exercise can also help to reduce stress levels and improve overall heart health.
Meditation, yoga, and other relaxation techniques have been shown to have a positive impact on heart health. A study published in the Journal of the American College of Cardiology found that regular meditation practice was associated with a reduction in blood pressure, which can lower the risk of heart disease. Yoga has also been shown to improve heart health by reducing stress and inflammation.
The Role of Sleep
Sleep plays a crucial role in heart health. Poor sleep quality and quantity have been linked to an increased risk of heart disease, high blood pressure, and other cardiovascular problems. Sleep deprivation can also increase inflammation in the body, which can contribute to the development of heart disease.
For adults, the recommended amount of sleep is 7-9 hours per night. Children and teenagers require more sleep, with infants needing up to 14 hours per day and teenagers needing up to 10 hours per night.
To improve sleep quality and quantity, it is important to establish a regular sleep schedule, avoid caffeine and alcohol before bedtime, create a relaxing sleep environment, and limit screen time before bed. Regular exercise can also help to improve sleep quality and overall heart health.
