He died in 2016 from pulmonary embolism (PE), a blood clot in the lung. The hospital claims that post-surgery exercise, which can help prevent PE, was prescribed after surgery. However, CCTV footage shows no exercise being administered, and the caregiver has said that they didn't help him exercise.
He later felt his heart racing and experienced chest pain, so paramedics were called to transfer him to another hospital better suited for his complication. The hospital claims that the paramedics arrived in two minutes, meanwhile actual CCTV footage showed that they arrived in 22 minutes.
The case is being discussed now since there still isn't closure, as the hospital has denied wrongdoing, not having apologized to the family.

Medical historyYou're at higher risk if you or any of your family members have had venous blood clots or pulmonary embolism in the past. This may be due to inherited disorders that affect blood, making it more prone to clot.
In addition, some medical conditions and treatments put you at risk, such as:
- Heart disease. Cardiovascular disease, specifically heart failure, makes clot formation more likely.
- Cancer. Certain cancers — especially pancreatic, ovarian and lung cancers, and many cancers with metastasis — can increase levels of substances that help blood clot, and chemotherapy further increases the risk. Women with a personal or family history of breast cancer who are taking tamoxifen or raloxifene also are at higher risk of blood clots.
- Surgery. Surgery is one of the leading causes of problem blood clots. For this reason, medication to prevent clots may be given before and after major surgery such as joint replacement.
Prolonged immobilityBlood clots are more likely to form during periods of inactivity, such as:
- Bed rest. Being confined to bed for an extended period after surgery, a heart attack, leg fracture, trauma or any serious illness makes you more vulnerable to blood clots. When the lower extremities are horizontal for long periods, the flow of venous blood slows and blood can pool in the legs.
- Long trips. Sitting in a cramped position during lengthy plane or car trips slows blood flow in the legs, which contributes to the formation of clots.
Other risk factors - Smoking. For reasons that aren't well-understood, tobacco use predisposes some people to blood clot formation, especially when combined with other risk factors.
- Being overweight. Excess weight increases the risk of blood clots — particularly in women who smoke or have high blood pressure.
- Supplemental estrogen. The estrogen in birth control pills and in hormone replacement therapy can increase clotting factors in your blood, especially if you smoke or are overweight.
- Pregnancy. The weight of the baby pressing on veins in the pelvis can slow blood return from the legs. Clots are more likely to form when blood slows or pools.
PreventionPreventing clots in the deep veins in your legs (deep vein thrombosis) will help prevent pulmonary embolism. For this reason, most hospitals are aggressive about taking measures to prevent blood clots, including:
- Blood thinners (anticoagulants). These medications are often given to people at risk of clots before and after an operation — as well as to people admitted to the hospital with a heart attack, stroke or complications of cancer.
- Compression stockings. Compression stockings steadily squeeze your legs, helping your veins and leg muscles move blood more efficiently. They offer a safe, simple and inexpensive way to keep blood from stagnating during and after general surgery.
- Leg elevation. Elevating your legs when possible and during the night also can be very effective. Raise the bottom of your bed 4 to 6 inches with blocks or books.
- Physical activity. Moving as soon as possible after surgery can help prevent pulmonary embolism and hasten recovery overall. This is one of the main reasons your nurse may push you to get up, even on your day of surgery, and walk despite pain at the site of your surgical incision.
- Pneumatic compression. This treatment uses thigh-high or calf-high cuffs that automatically inflate with air and deflate every few minutes to massage and squeeze the veins in your legs and improve blood flow.
