Heart Attack Causes Head-Ache – Cardiac Cephalalgia Acta Cardiol Sin 2016;32:239-242 Case Report doi: 10.6515/ACS20150628A Heart Attack Causes Head-Ache – Cardiac Cephalalgia Chi-Cheng Huang and Pen-Chih Liao Chest pain is the typical symptom of myocardial infarction (MI), and there are many atypical manifestations such as stomachache or dyspnea. Headache is a rare presentation of MI, which has specifically been termed “cardiac cephalalgia” or “cardiac cephalgia”. In this article, we have reported a case of sudden onset headache and neck pain, of whom MI was confirmed by electrocardiography, cardiac markers, and coronary angiogram. The patient’s headache subsided dramatically after coronary angioplasty, and it had not recurred in the following one year. Additionally, diagnostic clues and possible mechanisms of cardiac cephalalgia are discussed as well.

  • Evaluation of Abdominal Pain in the Emergency Department Hartmut Gross, M.D., FACEP
    Evaluation of Abdominal Pain in the Emergency Department Hartmut Gross, M.D., FACEP Abdominal pain complaints comprise about 5% of all Emergency Department visits. The etiology of the pain may be any of a large number of processes. Many of these causes will be benign and self-limited, while others are medical urgencies or even surgical emergencies. As with any complaint in the ED, the worst diagnosis is always entertained first. Therefore, there is one thought, which the ED practitioner must maintain in the foreground of his mind: “Is there a life threatening process?” Etiology A breakdown of the most common diagnoses of abdominal pain presentations is listed below. Note that nearly half of the time, “unknown origin” is the diagnosis made. This is a perfectly acceptable conclusion, after a proper work-up has ruled out any life threatening illness. Common Diagnoses of Non-traumatic Abdominal Pain in the ED 1 Abdominal pain of unknown origin 41.3% 2 Gastroenteritis 6.9% 3 Pelvic Inflammatory Disease 6.7% 4 Urinary Tract Infection 5.2% 5 Ureteral Stone 4.3% 6 Appendicitis 4.3% 7 Acute Cholecystitis 2.5% 8 Intestinal Obstruction 2.5% 9 Constipation 2.3% 10 Duodenal Ulcer 2.0% 11 Dysmenorrhea 1.8% 12 Simple Pregnancy 1.8% 13 Pyelonephritis 1.7% 14 Gastritis 1.4% 15 Other 12.8% From Brewer, RJ., et al, Am J Surg 131: 219, 1976. Two important factors modify the differential diagnosis in patients who present with abdominal pain: sex and age. Other common diagnoses of abdominal pain in men and women are as follows.

  • Costochondritis
    Department of Rehabilitation Services Physical Therapy Standard of Care: Costochondritis Case Type / Diagnosis: Costochondritis ICD-9: 756.3 (rib-sternum anomaly) 727.2 (unspecified disorder of synovium) Costochondritis (CC) is a benign inflammatory condition of the costochondral or costosternal joints that causes localized pain. 1 The onset is insidious, though patient may note particular activity that exacerbates it. The etiology is not clear, but it is most likely related to repetitive trauma. Symptoms include intermittent pain at costosternal joints and tenderness to palpation. It most frequently occurs unilaterally at ribs 2-5, but can occur at other levels as well. Symptoms can be exacerbated by trunk movement and deep breathing, but will decrease with quiet breathing and rest. 2 CC usually responds to conservative treatment, including non-steroidal anti-inflammatory medication. A review of the relevant anatomy may be helpful in understanding the pathology. The chest wall is made up of the ribs, which connect the vertebrae posteriorly with the sternum anteriorly. Posteriorly, the twelve ribs articulate with the spine through both the costovertebral and costotransverse joints forming the most hypomobile region of the spine. Anteriorly, ribs 1-7 articulate with the costocartilages at the costochondral joints, which are synchondroses without ligamentous support. The costocartilage then attaches directly to the sternum as the costosternal joints, which are synovial joints having a capsule and ligamentous support. Ribs 8-10 attach to the sternum via the cartilage at the rib above, while ribs 11 and 12 are floating ribs, without an anterior articulation. 3 There are many causes of musculo-skeletal chest pain arising from the ribs and their articulations, including rib trauma, slipping rib syndrome, costovertebral arthritis and Tietze’s syndrome.

  • Pseudoanginal Chest Pain Associated with Vagal Nerve Stimulation: a Case Report James B
    Nichols et al. BMC Neurology (2020) 20:144 https://doi.org/10.1186/s12883-020-01693-5 CASE REPORT Open Access Pseudoanginal chest pain associated with vagal nerve stimulation: a case report James B. Nichols1, Abigail P. McCallum1, Nicolas K. Khattar1, George Z. Wei1, Rakesh Gopinathannair2, Haring J. W. Nauta1 and Joseph S. Neimat1* Abstract Background: Vagal nerve stimulation (VNS) can be an effective therapy for patients with epilepsy refractory to anti- epileptic drugs or intracranial surgery. While generally well tolerated, it has been associated with laryngospasm, hoarseness, coughing, dyspnea, throat and atypical chest pain, cardiac symptoms such as bradycardia and occasionally asystole. We report on a patient receiving vagal nerve stimulation who experienced severe typical anginal chest pain during VNS firing without any evidence of cardiac ischemia or dysfunction. Thus, the pain appeared to be neuropathic from the stimulation itself rather than nociceptive secondary to an effect on heart function. Case presentation: A 29-year-old man, with a history of intractable frontal lobe epilepsy refractory to seven anti- epileptic medications and subsequent intracranial surgery, underwent VNS implantation without complications. On beginning stimulation, he began to have intermittent chest pain that corresponded temporally to his intermittent VNS firing. The description of his pain was pathognomonic of ischemic cardiac chest pain. On initial evaluation, he displayed Levine’s sign and reported crushing substernal chest pain radiating to the left arm, as well as shortness of breath walking upstairs that improved with rest. He underwent an extensive cardiac workup, including 12-lead ECG, cardiac stress test, echocardiogram, 12-day ambulatory cardiac monitoring, and continuous ECG monitoring each with and without stimulation of his device.

  • Surgical Treatment of Angina Pectoris He Extensive
    SURGICAL TREATMENT OF ANGINA PECTORIS INGA LINDGREN, M.D., AND HERBERT OLIVECRONA, M.D. Neurosurgical Clinic, Serafimerlasarettet, (Director: Professor H. Olivecrona) and IVth Medical Service, St. Erik's Hospital (Director: Professor H. Berglund), Stockholm, Sweden (Received for publication October ~3, 1946) HE EXTENSIVE researches of Blumgart I have shown that the structural basis for coronary pain is an arteriosclerotic process with obstruction T or obliteration of one or more coronary arteries before an adequate collateral circulation has been developed. On the other hand, if the develop- ment of the collateral circulation has kept pace with the progressive arterial narrowing, myocardial damage and pain are absent even if one or more of the coronary arteries are obstructed. If the increased blood supply to the myocardium demanded by muscu- lar exercise cannot be delivered through the ordinary or collateral channels, coronary pain results. A short rest is usually sufficient to restore the circula- tory balance and the pain subsides. Dilatation of the coronary arteries by nitroglycerine hastens the process and may, if the drug is taken before muscular exertion, prevent an anticipated attack. Vasoconstriction, on the other hand, is an important factor in anginal pain. Practically every sufferer from angina pectoris is worse in the winter; his capacity for muscular work is much less in cold weather. Sudden cooling from any cause is frequently sufficient to bring on an attack. Freedberg, 7 in a series of experiments, has been able to show the effect of cooling upon the exercise tolerance in angina pectoris. He found by testing the same patient's capacity for exercise at different temperatures that the tolerance was much less at temperatures of 7-13~ (45-55~ than at ~4~ (75~ His in- vestigations thus lend experimental support to clinical experience that cold weather has a bad effect on sufferers from angina pectoris.

In her work on the study of trigger points, Janet Travel, MD1 spoke of her observations that trigger points in the Pectoralis Major seemed to generate reflexive reaction in the heart resulting in irregular heart beats. Sometimes the pain originating in the tight tender areas of this muscle were perceived by the patient as coming from their heart. Pectoralis Major Muscle and the Cardiac Trigger Point Phenomena A) overlapping referred pain patterns of two parasternal trigger points (x’s), located in the medial sternal section of the muscle B) location of the “cardiac arrhythmia” trigger point (x) below the lower border of the fifth rib in the vertical line that lies midway between the sternal margin and the nipple line. On this line the sixth rib is found at the level of the tip of the xiphoid process (arrow) This vertical line corresponds to the pathway of the Kidney Meridian and the trigger points are found at K21, 22 Other authors have spoken of the relationships between dysfunction of the Pectoralis Major and associations with cardiac dysfunction Schwartz and Bourassa2 state that in the Coronary Artery Surgery Study Registry of the 1970s, normal angiograms were found in 19% of patients, and suggest that the statistics today are not much different .
