It is generally believed that heart attack occurs only in those people whose cholesterol level is very high or who have severe blockage in their coronary arteries. But medical science and famous cardiologists believe that this notion is not completely correct. In today's time, many such cases are coming to light where all the reports of the person are normal, no blockage is visible in Angiography and cholesterol is also completely controlled, yet the person suddenly becomes a victim of silent heart attack or cardiac arrest. According to cardiologists, apart from blockage, there are many invisible reasons which directly affect the health of your arteries and heart.
According to doctors, in angiography or routine tests, only those blockages are detected which have become quite large and hard. But sometimes very fine and soft plaque gets deposited in the walls of the arteries, which is not easily visible in any normal test. When a person undergoes extreme physical stress, sudden mental pressure or inflammation, this small soft plaque suddenly bursts. When the plaque bursts, the body's defense system immediately forms a blood clot there, due to which the blood flow to the heart stops completely within a moment and the person suffers a serious heart attack.
The other main reasons for heart attack without blockage are 'Coronary Vasospasm' and 'Endothelial dysfunction'. Endothelium is the inner layer of our blood vessels. When there is a malfunction, the arteries suddenly start narrowing excessively. This is called spasm. When there is a sudden sharp spasm or contraction in the main artery of the heart, blood flow stops completely for a few moments. This condition can directly lead to cardiac arrest or heart attack even without any permanent blockage or high cholesterol. This risk increases further due to excessive smoking, stress and cold weather.
In modern times, increased mental stress, chronic depression and lack of sleep rapidly increase the level of stress hormones like 'cortisol' and 'adrenaline' in the body. These hormones cause the heartbeat and blood pressure to spike suddenly. Along with this, the silent inflammation going on inside the body weakens the inner walls of the blood vessels. Excessive consumption of processed food, sedentary lifestyle and excessive smoking are also increasing the number of heart attacks without causing any major blockage.
If you want to always keep your heart safe and healthy, then do not be worried just if the lipid profile or ECG test comes normal. Doctors recommend that every person should get a high-sensitivity C-reactive protein (hs-CRP) test done at least once a year, which accurately detects hidden internal inflammation in the body. Apart from this, take a 30 to 45 minute walk or exercise daily, include natural anti-oxidants in your diet, stay away from smoking and alcohol and try yoga and meditation to manage your stress levels. If you feel heaviness in the chest, unusual sweating, shortness of breath or pain in the jaw and left arm, contact a doctor immediately even if the report is normal.
