Remember to check your blood Pressure today.

Here are the key signs and symptoms of a heart attack (also called Myocardial Infarction). Recognizing them early can save a life.

⸻

🚨 Common Symptoms (Most Important)

❤️ Chest discomfort

* Pressure, squeezing, fullness, or pain in the center of the chest
* Lasts more than a few minutes or comes and goes

⸻

💪 Pain spreading to other areas

* Arms (especially left arm)
* Back, neck, jaw, or shoulders

⸻

😮‍💨 Shortness of breath

* May happen with or without chest pain

⸻

🤢 Other common signs

* Nausea or vomiting
* Cold sweat
* Lightheadedness or dizziness

⸻

⚠️ Less Obvious Symptoms (Common in women, elderly, diabetics)

* Unusual fatigue
* Indigestion or heartburn-like feeling
* Mild chest discomfort instead of severe pain
* Sudden weakness

👉 These can be mistaken for minor issues but may still be serious.

⸻

⏱️ When to Act

If you or someone has:

* Chest pain/discomfort lasting >5 minutes
* OR multiple symptoms above

👉 Call emergency services immediately (911 in Canada)
👉 Do NOT wait or try to “sleep it off”

⸻

💊 Quick First Aid (While waiting for help)

* Have the person sit and rest
* If not allergic and conscious: chew an Aspirin (helps thin blood)
* Loosen tight clothing

🧠 Important Tip

Not all heart attacks are dramatic. Some are “silent” or mild—but still dangerous.

Preventing heart disease is mostly about consistent daily habits. The good news is that small changes can make a big difference over time.

🫀 Key Ways to Protect Your Heart

1. Eat a heart-healthy diet
• Focus on fruits, vegetables, whole grains, and lean proteins
• Choose healthy fats (like olive oil, nuts, fish)
• Limit salt, sugar, and processed foods

2. Stay physically active
• Aim for at least 150 minutes of moderate exercise per week (walking, cycling, dancing)
• Even simple activities like taking the stairs or walking more help

3. Maintain a healthy weight
• Extra body weight—especially around the waist—raises heart risk
• Balanced eating + regular movement helps manage weight

4. Don’t smoke
• Smoking damages blood vessels and greatly increases heart disease risk
• If you don’t smoke, don’t start; if you do, quitting is one of the best things you can do

5. Manage stress
• Chronic stress can affect your heart
• Try relaxation techniques like deep breathing, meditation, or hobbies you enjoy

6. Get good sleep
• Aim for 7–9 hours per night
• Poor sleep is linked to high blood pressure and heart problems

7. Monitor your health
• Keep track of:
• Blood pressure
• Cholesterol
• Blood sugar
• Regular checkups help catch issues early.

Heart failure is a condition where the heart cannot pump blood effectively to meet the body’s needs. Its signs and symptoms result from fluid buildup (congestion) and reduced cardiac output.

Common Symptoms (what the patient feels)
• Shortness of breath (dyspnea)
• On exertion (early)
• At rest (advanced)
• Orthopnea (breathlessness when lying flat)
• Paroxysmal nocturnal dyspnea (PND) (sudden breathlessness at night)
• Fatigue and weakness
• Reduced exercise tolerance
• Swelling (edema)
• Feet, ankles, legs
• Abdomen (ascites)
• Rapid weight gain (due to fluid retention)
• Persistent cough
• Often worse at night
• May produce frothy sputum (sometimes pink)
• Loss of appetite, nausea
• Increased urination at night (nocturia)

⸻

Common Signs (what a clinician finds)
• Tachycardia (fast heart rate)
• Elevated jugular venous pressure (JVP)
• Peripheral edema (pitting swelling in legs)
• Pulmonary crackles (rales) on auscultation
• S3 gallop (extra heart sound)
• Hepatomegaly (enlarged liver)
• Ascites
• Cyanosis (in severe cases)
• Cold extremities (poor perfusion)

⸻

Left vs Right Heart Failure

Left-sided failure (lung symptoms):
• Dyspnea
• Orthopnea
• PND
• Pulmonary edema (crackles)

Right-sided failure (systemic congestion):
• Peripheral edema
• Hepatomegaly
• Ascites
• Raised

Heart Failure develops when the heart becomes weak or stiff over time. Several conditions can lead to this.

⸻

🔹 Major causes

1. High blood pressure
• High Blood Pressure forces the heart to work harder
• Over time, the heart muscle thickens and weakens

⸻

2. Coronary artery disease
• Coronary Artery Disease reduces blood flow to the heart
• Can damage the heart muscle

⸻

3. Heart attack
• Myocardial Infarction causes permanent damage to heart tissue
• Weakens the heart’s pumping ability

⸻

4. Diabetes
• Diabetes Mellitus damages blood vessels and the heart over time

⸻

5. Heart valve disease
• Faulty valves make the heart work harder
• Leads to enlargement and weakening

⸻

6. Cardiomyopathy
• Disease of the heart muscle itself
• Can be caused by genetics, alcohol, infections

⸻

7. Chronic lung diseases
• Conditions like Chronic Obstructive Pulmonary Disease increase pressure on the heart

⸻

8. Lifestyle factors
• Smoking
• Excess alcohol use
• Poor diet (high salt, high fat)
• Lack of exercise
• Obesity

⸻

🔹 Other contributing causes
• Severe anemia
• Thyroid disorders
• Infections affecting the heart
• Congenital heart defects (present at birth)

⸻

🔹 Simple exam definition

Causes of heart failure: Conditions that damage or overwork the heart, leading to reduced pumping ability.
