5 Subtle Warning Signs of Heart Disease You Should Never Ignore
At Harlem Cardiology on Madison Avenue in New York City, we know that heart issues do not always start with dramatic chest pain. Dr. Henock Saint-Jacques and our team help patients in East Harlem recognize the subtle, easily missed signs of cardiovascular trouble.
Many people expect a heart attack to feel like a sudden, crushing pressure. However, early heart disease often presents with quiet, atypical symptoms that are easy to ignore.
These symptoms are not truly silent, but they are frequently mistaken for everyday issues like aging or indigestion. Understanding how your body signals distress can help you seek care before an emergency occurs. Here are five warning signs you should discuss with a cardiologist.
1. Shortness of breath during daily activities
Feeling unusually winded during simple tasks like climbing stairs can be an early sign of heart disease.
A 2021 guideline from the American Heart Association notes that shortness of breath is a common "anginal equivalent." This means it can indicate reduced blood flow to your heart. This symptom is especially common in women, older adults, and people with diabetes.
At our New York City office, we offer a stress test to evaluate how your heart handles physical exertion.
2. Unexplained, profound fatigue
Feeling completely exhausted after normal daily activities can point to an underlying heart condition.
A 2025 systematic review in the Journal of Advanced Nursing studied women experiencing heart issues. The researchers found they often report profound fatigue and sleep disturbances well before an acute cardiac event.
If you are constantly tired, Dr. Saint-Jacques can perform an EKG to check your heart's electrical activity.
3. Sudden nausea or abdominal discomfort
Unexplained nausea, indigestion, or vague stomach discomfort can actually stem from poor blood flow to the heart.
A 2024 systematic review in Cureus evaluated patients with diabetes. These patients often experience atypical symptoms like nausea or abdominal pain rather than classic chest pressure. This occurs because diabetic neuropathy can damage the nerves that transmit pain signals, masking typical chest pain.
We evaluate these symptoms using noninvasive imaging, such as an echocardiogram.
4. Dizziness or lightheadedness
Feeling dizzy or lightheaded when you stand up or exert yourself can mean your heart is not pumping enough blood to your brain.
Our team routinely evaluates these symptoms to rule out conditions like heart failure.
The American Heart Association also notes that lightheadedness is a key atypical symptom that warrants professional evaluation.
5. Pain in the jaw, neck, back, or arm
Heart-related discomfort does not always stay in the chest; it can radiate to your upper body, including your jaw, neck, back, or arms.
The American Heart Association guidelines explain that myocardial ischemia is a lack of blood flow to the heart muscle. This condition can manifest as discomfort across any of these upper body zones.
If you experience recurring discomfort in these areas during physical activity, we can help you identify the cause and create a personalized prevention plan.
Do not wait for a cardiovascular emergency to take action. If you notice any of these subtle warning signs, schedule a visit with Dr. Saint-Jacques today. Our team at Harlem Cardiology on Madison Avenue is here to protect your heart health.
