Heart attack

A heart attack, medically called a myocardial infarction (MI), happens when blood flow to part of the heart muscle becomes severely reduced or blocked. Without enough blood and oxygen, the affected heart muscle begins to become damaged. A heart attack is a medical emergency. Fast treatment can restore blood flow, limit heart-muscle damage and improve the chances of recovery. The most commonly recognised symptom is chest discomfort, which may feel like pressure, squeezing, tightness, heaviness or aching. However, a heart attack does not always look the same in every person. Some people may mainly experience breathlessness, nausea, sweating, unusual tiredness, dizziness or discomfort in the arm, back, neck or jaw. Never wait for symptoms to become severe before seeking help.

Introduction


   

      Heart health is an important part of overall wellbeing.

      The cardiovascular system continuously supplies oxygen

      and nutrients to different parts of the body.

   


   

      Many cardiovascular conditions can be influenced by

      lifestyle, blood pressure, cholesterol, diabetes,

      smoking, physical activity, diet, and family history.

   


 



 


   

      Why Heart Health Matters

   


   

      Maintaining cardiovascular health may reduce the risk

      of several heart-related conditions and support overall

      physical wellbeing.

   


   

         
  • Maintaining healthy blood pressure
  •      
  • Managing cholesterol levels
  •      
  • Staying physically active
  •      
  • Following a balanced diet
  •      
  • Avoiding tobacco and smoking
  •      
  • Maintaining a healthy body weight
  •      
  • Managing diabetes when applicable
  •    


     



     


       

          Common Heart Health Risk Factors

       


       

          Some cardiovascular risk factors can be modified through

          lifestyle changes, while others may require medical

          monitoring and professional guidance.

       


       

    High Blood Pressure


       

          High blood pressure can place additional strain on the

          heart and blood vessels. Regular monitoring can help

          identify abnormal readings.

       


       

    High Cholesterol


       

          Cholesterol is necessary for several functions in the

          body, but abnormal cholesterol levels can be associated

          with cardiovascular risk.

       


       

    Diabetes


       

          Diabetes can affect blood vessels and cardiovascular

          health. Keeping blood glucose levels within the range

          recommended by a healthcare professional is important.

       


       

    Smoking


       

          Tobacco use can negatively affect blood vessels and

          cardiovascular health. Avoiding tobacco is an important

          part of heart-health prevention.

       


     



     


       

          Healthy Habits for Your Heart

       


       

          Small and consistent lifestyle changes can contribute

          to better cardiovascular health.

       


       

           
    1.         Stay physically active.

              Aim for regular physical activity according to your

              health condition and your healthcare professional's advice.

           


           
    2.         Choose a balanced diet.

              Include vegetables, fruits, whole grains, and other

              nutrient-rich foods as appropriate.

           


           
    3.         Monitor your health.

              Keep track of blood pressure, blood glucose,

              cholesterol, or other measurements when recommended.

           


           
    4.         Avoid tobacco.

              Avoiding smoking and other tobacco products can support

              cardiovascular health.

           


           
    5.         Prioritize sleep.

              Maintain a consistent sleep routine and discuss

              persistent sleep problems with a healthcare professional.

           

         


       



       


         

            Warning Signs That Should Not Be Ignored

         


         

            Some symptoms may require urgent medical attention.

            Seek emergency medical care if you experience symptoms

            such as:

         


         

             
      • Severe or persistent chest discomfort
      •      
      • Shortness of breath
      •      
      • Sudden unexplained sweating
      •      
      • Fainting or severe dizziness
      •      
      • Sudden weakness
      •      
      • Unusual pain spreading to the arm, shoulder, back, neck, or jaw
      •    


           

             

                If you believe you may be experiencing a medical emergency,

                seek immediate medical assistance rather than relying on

                online information.

             

           


         



         


           

              When Should You Talk to a Doctor?

           


           

              Consider discussing your cardiovascular health with a

              qualified healthcare professional if you have persistent

              symptoms, abnormal blood pressure or cholesterol readings,

              diabetes, a family history of heart disease, or other

              concerns about your heart health.

           


           

              Your doctor can assess your individual health history

              and recommend appropriate examinations or tests when needed.

           


         



         


           

              Frequently Asked Questions

           



           

             

                How can I improve my heart health?

             


             

                Regular physical activity, a balanced diet, avoiding

                tobacco, maintaining healthy blood pressure and cholesterol,

                and following appropriate medical advice can support

                cardiovascular health.

             

           



           

             

                How often should I check my blood pressure?

             


             

                The appropriate frequency depends on your individual

                health status. People with hypertension or other

                cardiovascular risk factors may need more frequent

                monitoring as advised by their healthcare professional.

             

           



           

             

                Can lifestyle changes reduce cardiovascular risk?

             


             

                Healthy lifestyle choices can contribute to cardiovascular

                health. The impact varies between individuals and depends

                on existing health conditions and risk factors.
