Conclusion
Only one of the symptoms above isn’t sufficient to confirm an impending heart attack. It takes more than one of these symptoms alongside diagnosis by your doctor to confirm an impending heart attack. High blood pressure [9] and high level of cholesterol [10] are one of the warning signs of an impending heart attack. Each of these conditions block the flow of blood to the heart. Bad cholesterol blocks the flow of blood, and a high blood pressure makes the arteries thinner. Thinner arteries make the resistance to blood flow high, and this spells an impending heart attack.
