رجل عمره ٧٢ سنة عنده فشل قلب مستقر، يأخذ مدر بول وموصى له بتقييد السوائل ١٫٥ لتر يومياً. يخطط للحج هذا الصيف حيث الحرارة تتجاوز ٤٥ درجة، ويسأل عن الاستعداد. أي نصيحة صحيحة؟

A 72-year-old man with stable heart failure takes a diuretic and has a 1.5 L/day fluid restriction. He plans to perform Hajj this summer with temperatures above 45 °C and asks how to prepare. Which advice is correct?

1. Drink very large amounts of water all day without limits
2. Stop the medicines because the walking will replace them
3. See the doctor first and know his fluid and weight limits
4. Stop the diuretic throughout Hajj because it causes thirst

Answer: C) See the doctor first and know his fluid and weight limits. Heat and exertion can cause dehydration or congestion in cardiac patients. The doctor sets a fluid and medication plan, weight and symptoms are monitored, and extreme heat is avoided.
