Warning Signs Before a Heart Attack

Unusual Fatigue

• Tiredness without a specific reason
• Related to ischemia (lack of blood flow)
  • Heart struggles due to insufficient blood supply
  • Leads to less energy production and fatigue
• Different from sleepiness; it's a physical fatigue
• Affects the whole body, persistent and general

Mild Angina

• Chest pain, pressure, or discomfort
• Caused by ischemia and lack of oxygen to the heart
• Early symptoms can progress to a heart attack

Shortness of Breath

• Results from reduced blood flow and oxygen supply
• Breathing becomes more difficult, especially during exertion
• Can lead to fluid buildup in lungs due to increased pressure

Sweating

• Occurs even at rest, due to heart stress
• Activates sympathetic nervous system (fight or flight response)

Unexplained Weakness

• More severe physical weakness, could be localized
• Sudden onset may indicate impending heart attack

Nausea and Vomiting

• Related to vagus nerve (parasympathetic response)
• Heart stress causes mixed signals affecting digestion

Dizziness or Lightheadedness

• Caused by reduced cardiac output affecting blood flow to the brain

Severe Chest Pain or Pressure

• Feels like crushing pressure, significant blockage
• Immediate medical attention needed

Radiating Pain

• Pain spreading to left arm, jaw, neck, or shoulders
• Indicates referred pain due to shared sensory pathways
• Sign of severe heart stress

Severe Shortness of Breath

• Occurs all the time, fluid buildup in lungs worsens
• Weaker heart, less oxygenated blood circulation
• Vicious cycle, seek immediate help

Prevention and Lifestyle Change

• Heart issues linked to metabolic disease
• Importance of early intervention
• Focus on reducing insulin resistance, metabolic disease
• Address chemical stress, exercise, mental stress
• Educational resources available for further learning

Conclusion

• Change lifestyle early to prevent severe heart issues
• Various resources and videos available for guidance
